Утепление керамзитобетонных стен: Как и чем утеплить стены из керамзитобетонных блоков (снаружи и изнутри)

Утепление стен керамзитом, преимущества и технология

Все давно поняли, что лучший способ сделать дом, коттедж или общественное здание теплыми – это не просто включить котел на максимум и тратить массу средств на такие услуги. Ведь вырабатываемое тепло будет выходить через стены, крышу, пол, оконные и дверные отверстия. Теплый дом – тот, что будет сохранять тепло внутри. Благодаря снижению теплопотерь, внутри будет тепло и уютно, а на отопление уйдет меньше средств. И его уже готовое здание можно утеплить доступными материалами, такими как минеральная вата, пенопласт, пенoполиуретан и экoвата, то существует альтернативный способ – утепление стен керамзитом в процессе кладки. Такoй вариант доступный и эффективный. Керамзитные стены способны снизить потери тепла через фасад вплоть до 75%.

Понятие керамзита и критерии выбора

Что такое керамзит? Это утеплительный материал рассыпчатого типа. Он представляет собой мелкие сыпучиe фрaгменты, имеющие пористую структуру. Изготовляют его в процессе вспенивaния глины легкоплавкогo типа и сланцев. В качестве добавок могут быть использованы опилки из древесины, торфяник, соляровое масло. На финишном этапе утеплитель катается в барабанах и проходит печной обжиг. Повышенная температура придает шарикам керамзита большую прочность.

На выходе образуются прочные, но легкие шарики, размером 2–40 мм. По фракции, керамзит для утепления стен, делится на песок (размеры до 5 мм), щебень (на вид как кубики), гравий, имеющий продолговатую форму.

Интересный факт! Специалисты заявляют, что слой керамзита в 10 см по своим теплоизоляционным характеристикам равняется кирпичной стене толщиной в 1 м, или толщине дерева в 25 см.

Чтобы утепление керамзитом не было напрасным и материал полноценно выполнял свои функции, важно правильно выбрать фракцию для каждого региона. Рассмотрим особенности каждой из них:

1. Песок. Это глинистая мелочь, которую добывают при отсеве основного сырья. Кроме того, большие куски керамзита могут специально дробить в шахтных печах. Для чего используется керамзитный песок? Все зависит от величины. Например, сырье размером до 5 мм применяется для создания цементной стяжки пола. При этом толщина заливочного слоя составляет не более 20 см. Если фракция керамзитного песка размером до 3 мм, то его добавляют в смесь цемента, для создания кладочного раствора. Он будет иметь теплоизоляционные характеристики.
2. Керамзитная щебень. Она образуется путем дробления на куски крупной глины, которая уже запеклась. Щебень служит теплоизоляционным наполнителем. Ее используют для создания бетонных конструкций с небольшой удельной плотностью.
3. Керамзитный гравий. Это овальные или округлые гранулы. Сфера использования этой фракции наибольшая. Все зависит от размера. Например, гравий от 20 до 40 мм характеризуется наименьшей насыпной плотностью. Поэтому он хорошо зарекомендовал себя в случаях, когда нужно засыпать толстый теплоизоляционный слой (основание фундамента, погреб, чердачное перекрытие. Фракция от 10 до 20 мм – идеальный способ утеплять пол, кровлю, стены, сделанные по технологии колодцевой кладки. Гравий размером от 5 до 10 мм применяется для основания пот теплый пол. Им можно выполнять наружную теплоизоляцию фасада. А сделав цементную смесь с керамзитом, можно залить пространство между кладкой и облицовочным материалом.

Это были разновидности керамзита как утеплителя. Но, чтобы сделать правильный выбор важно учесть некоторые особенности и характеристики материала:

• Свойство изоляции тепла и звука. Важным критерием любого теплоизолятора является коэффициент теплопроводности. В идеале выбирать гранулы с наименьшей проводимостью тепла. Для насыпного утепления лучше подойдут гранулы размером от 10 до 20 мм.
• Показатель насыпной плотности. Для обустройства фундамента этот показатель самый важный. Поэтому важно обращать внимание на качество исходного сырья, соблюдался ли технологический процесс при обработке в печи. Для улучшения прочности иногда применяются дополнительные вещества.
• Свойство поглощать влагу. Коэффициент корреляции у керамзита должен быть 0,46, не меньше. При снижении числа сырье будет впитывать в себя влагу и сохранять ее. Такая продукция не является качественной.
• Устойчивость перед грибком и процессу гниения. Поражение грибком и гнилью говорит о том, что используемые добавки были некачественными. Для утепления стен материал не подходит.
• Устойчивость к влиянию открытого пламени. Керамика повысит пожарную безопасность конструкции.

Учитывая все эти особенности, каждый сможет выбрать керамзит для утепления стен, пола, чердака, фундамента или другой конструкционной части помещения.

Преимущества керамзита в качeстве утеплителя для стен

Почему керамзит пользуется таким спросом в качестве утеплителя? Благодаря особенностям теплоизолятора и технологии создания, он приобретает явные преимущества перед другими материалами. Вот их перечень:

1. Доступная стоимость. Обычно процесс утепления предполагает весомые вложения средств. Керамзит имеет низкую цену, что позволяет использовать его повсеместно.
2. Есть возможность не только возводить стены из керамических блоков, но и использовать его в качестве насыпного утеплителя, сырья для создания теплого бетонного раствора.
3. Утеплитель сделан из глины, сланца и других натуральных, экологически чистых материалов. А это значит, что они никак не будут влиять на окружающую среду и здоровье проживающих в доме.
4. Длительный эксплуатационный срок. По словам производителей, сырье может прослужить без изменений своих характеристик более 50 лет.
5. Материал не боится внешнего воздействия и влияния химических соединений. Он не будет ржаветь, гнить и разрушаться грызунами и насекомыми.
6. Простота в работе. Технология утепления не предполагает использование дорогостоящей спецтехники и профессиональных инструментов. Новичок с базовыми знаниями и набором инструментов сможет справиться с работой без посторонней помощи.
7. Прекрасные показатели звуко- и теплоизоляции. Материал пористый и его коэффициент теплопроводности низкий, а именно – 0,13 Вт/м^*К.
8. Минимальный вес, благодаря чему утепленные стены не будут сильно нагружены. Масса составляет от 200 кг/м³. Керамзит проще транспортировать и работать с ним.
9. Текстура у него сыпучая, а гранулы имеют небольшой размер. Поэтому керамзит можно засыпать полости и пространства любого размера.
10. Керамзит не боится колебаний температур, поэтому теплоизоляция хорошо выдерживает негативное влияние улицы.
11. Имеет отличные показатели защиты от влаги.
12. Обладает свойством пропускать пар, то есть, дышит. В помещении будет оптимальный микроклимат, никакого конденсата.

Этих преимуществ достаточно, чтобы назвать керамзит одним из лучших в своей области.

Отрицательные стороны утеплителя

Утепление стен керамзитом имеет и недостатки. Они такие:

• Материал не рекомендуется использовать для очень сырого помещения. Он будет долго высыхать, на время теряя свои характеристики. Но, этот недостаток решается путем использования гидрозащитной мембраны.
• Сухие гранулы образуют пыль при работе с ними. Поэтому процесс теплоизоляции требуется выполнять в респираторе.
• Так как керамзит – сыпучий материал, при укладке его следует уплотнять, чтобы впоследствии он не давал усадки.
• Для частного дома, гаража, подвала толщина слоя из керамзита должна быть в пределах 50 см и больше.

Как видно, недостатков у утеплителя намного меньше. Некоторые из них сразу отпадают, если речь идет об утеплении стен.

Утепление стен из кирпича керамзитом – технология

Керамзит является сыпучей разновидностью утеплителей. Это значит, что он засыпается в специально созданный каркас. Потому данный способ утепления хорош для стен, созданных из трех слоев. В работе есть важный момент – засыпать керамзит нужно поэтапно, постепенно, по мере того как растет кладка. Если засыпать материал с крыши, когда стена готова, то эффект утепления будет не такой. Рассмотрим несколько способов проведения работ.

Вариант 1 – легкая колодцевая кладка

Утепление стен керамзитом, технология легкой колодцевой кладки состоит в следующем: выкладывается 2 слоя стеновой кирпичной конструкции или кирпичей с блоками по рядам. Между ними соблюдается расстояние от 15 до 30 см. При этом есть закономерность – чем холоднее в регионе, тем шире делается расстояние между рядами.

Через один или два ряда кладка перевязывается кирпичными перемычками по всей толщине стены на расстоянии от 50 до 70 см. По мере возрастания конструкции будут образовываться колодцы, в которые на каждые 30–50 см засыпается керамзит. Для улучшения характеристик и предотвращения усадки он уплотняется. Делать это нужно осторожно, чтобы не повредить гранулы. Чтобы связать керамзит, его можно полить цементным молочком. Так называется жидкий раствор из цемента. Тогда усадка керамзита будет минимизированной.

Вариант 2 – колодцевая кладка с диафрагмами жесткости

Это наилучший вариант для утепления кирпичной кладки. Для его реализации нужно выложить ленты стены снаружи и внутри, толщина которых будет равняться в 1 и в полкирпича. Чтобы сделать дом еще и привлекательным, внешний ряд или ленту можно сделать из облицовочного кирпича. Также это делают из керамоблока, бетонных блоков под дальнейшую штукатурку, или из белого кирпича (силикатного).

Шаг между внешней и внутренней лентой остается таким, как в первом случае – от 10 до 30 см. Чтобы сделать коробку более жесткой, углы делаются сплошными. В пространство засыпается керамзит. Делается это с периодичностью в пять рядов кладки кирпича. Как в первом случае, сырье уплотняется и заливается молочком. Затем нужно выложить кирпичную диафрагму жесткости по всей толщине стены. Зачем это нужно? Чтобы сделать конструкцию более жесткой по высоте, не прибегая к использованию перевязочных анкеров.

Важно! Минус способа в том, что попасть в созданные карманы с керамзитом будет невозможно. И если в ходе эксплуатации утеплитель осядет после недостаточной трамбовки, то засыпать образовавшееся пространство не получится.

Вариант 3 – клада с использованием закладных деталей

Такой вариант напоминает первый описанный способ. Исключением является то, что вместо перемычек из кирпича в кладку вставляются анкеры из металла или стеклопластика. Это делается на расстоянии от 40 до 60 см. Это позволяет снизить расход кирпичей и не прибегать к высчитыванию шагов для возведения кладки. При всем этом, прочностные характеристики кладки остаются на таком же уровне. Керамзит нужно засыпать на такие же 30–50 см. Этот объем позволит проще проводить утрамбовку и пропитывать слой цементным молочком.

Мы рассмотрели утепление керамзитом стен во время их возведения. Это эффективный способ сделать их теплее за небольшие деньги. А с учетом того, сколько преимуществ имеет данный утеплитель, можно не сомневаться, что при правильной технологии, на протяжении долгих лет дом останется теплым и уютным.

90000 Features leveling subfloors using expanded clay 90001 90002 For qualitative repair subfloor, should carefully align it. This should be respected technology floor screed at all stages. If mistakes are tolerated, then later it will be difficult to put doors, partitions, etc .. For this purpose, mounting the screed conducted using kyeramzita. In addition to all this, the foundation will acquire additional quality. 90003 90004 Properties and quality 90005 90002 There are certain conditions, in which the best use of expanded clay for the screed.90003 90008 90009 Large drops the floor height of about 100 mm. 90010 90009 At the core of the floor laying — concrete or reinforced concrete slabs. 90010 90009 To improve the sound insulation level. 90010 90009 Reduces the consumption of cement. Which is also manifested in the large thickness of the floor of the future. 90010 90009 Uses for flooring planks, which does not allow the existence of any flaws, even minor sub-floor. This is mainly ceramic tiles, flooring, floating floor made from natural materials.90010 90009 Different heating systems (warm floor). 90010 90009 Hiding existing communications room. 90010 90023 90002 Furthermore ease the entire surface as a result of excellent quality is obtained. The load on the slab is reduced by a slight weight of the material. At the same time it is able to withstand external influences, including static loads. Over the entire period of operation the base is almost does not change its properties and qualities. 90003 90002 haydite specificity comes from the manufacturing process.The basic material — the fine clay, which is subjected to high temperature calcination. As a result, we get a light pellets, which do not pass moisture inside, They are very strong. 90003 90002 It is also worth noting, that depending on the size of the granules is isolated expanded clay sand, gravel or crushed stone. The sand fraction is typically up to 5 mm. The diameter of the gravel — up 40 mm, have a rounded shape, and crushed stone — well before 40 mm, but with the presence of corners. Its use will depend upon the floor covering, which subsequently will lay on the floor screed.90003 90002 If a floor leveling portion is very complicated and a large number of flaws, it is best to buy expanded clay sand. Its shrinkage is not significant and can cover all the problem areas. 90003 90004 Pros and cons of expanded clay 90005 90002 This material for floor screed has a huge number of positive features. Among them are the most basic and manifested: 90003 90036 90009 Operation period Duration. 90010 90009 ecological purity. 90010 90009 Sound and heat insulation qualities.90010 90009 Strength. floor screed with expanded clay with your hands get reliable and able to withstand the external pressure, both in static, and dynamics. 90010 90009 Accessibility in acquiring, reasonable cost. 90010 90047 90004 Markup and lighthouses 90005 90002 Before starting work on the floor leveling expanded clay should hold a series of preparatory activities. To do this, carefully cleaned the floor surface from dust and dirt, old ties. The best option — to make a sweep of the base slab.There will electric hammer or punch. Each of the tools will have a price. The former is more expensive, even if the lease, but it has better performance. 90003 90002 After that, start working on marking device. This step is necessary in order, to floor level remained the same in each of the rooms apartments. In addition to the level of the marker is useful also. To begin with the finished floor line is determined, which often coincides with the lower part of the door frame. The line between a connected spanned by a cord or using more modern — laser level.90003 90002 Then begins the most markup ties. Suffice it from the finished floor line down to measure the thickness of the fill. The resulting points are interconnected. As a result, we get another line, which will be a benchmark for the nomination in a subsequent beacon. 90003 90002 But for the nomination lighthouses screed with expanded clay in the apartment, should remove all the debris and dust from the base. Existing cracks should be sealed. If it does not perform, the strong possibility, to have carried out repeated repair.After wade through the slits may moisture. 90003 90002 On the floor of the piazza is the highest point, which sets the minimum height beacons. Usually they come in 6 mm. At the same time we must not forget about the use levels for. Subsequent beacons similarly exhibited by level, which must have a length of at least 2 m. The upper part of the beacons should be the same on marked lines marking. 90003 90002 various objects of the environment may be to adjust the height of beacons used. But it should be remembered that, that not everyone will be able to act as a tie element.This applies, Fiberboard fragments e.g., because it will swell from moisture. 90003 90002 If time permits, it is possible to knead the cement-sand mortar for fixing beacons. But it is best to apply the plaster. 90003 90004 Performing a semi-dry screeds 90005 90002 Virtually the only one, where little effort to prepare the base, is an polusuhaya screed. Enough to remove all the debris and dust, as well as the excess moisture. Everything else will be able to fix itself to the floor fill expanded clay.In the presence of the wires on the basis of, is best placed in the corrugation, then carefully fixed to the surface. 90003 90002 For the waterproofing layer may be a conventional PVC film. There is an alternative — a special steam (glassine). In this case, gravels floor screed will not get excess moisture from below. Moisture may appear on the intermediate floor, for various reasons. Fixing is done with tape of the film. We should not forget about the overlap of each subsequent deck around 10-15 cm.90003 90002 Further there is a marking exhibiting screed with a laser level. Instead, it can take and rack level. To keep warm, is inserted into the material along the walls in the room. It also contributes to excellent soundproofing. The gap is typically 10 cm. when all this is done under the floor screed concrete block crumbles evenly over the entire surface. Not everyone knows about, a concrete block for floor screed is the best solution. Everything will depend on the conditions and the choice of ties, as well as the preferences.No harm will consult a specialist on the matter. 90003 90002 Once selected two options floor screed pouring: 90003 90036 90009 Pour half expanded clay with their hands, directly, without additional layers. There will have to pre-fill material laitance. If it does not perform, the granules absorb moisture from a solution. Consequently, negative effects will manifest for sure. A little moisture may still leave the solution in expanded clay granules, but not in such numbers. 90010 90009 Use waterproofing layer between pouring.In podsypku not allow moisture even an ordinary polyethylene film. Most importantly make sure that, so that it does not break any of the sections of the floor in the room. 90010 90047 90002 For floor screed with expanded clay instruction must be followed immediately. If you are departing from one of the items, then in the end you can experience negative qualities, as a solution, and expanded clay for floor screed for underfloor heating. 90003 90004 Concrete screed 90005 90002 Concrete screed along with expanded clay called «expanded clay».But first, it is important to examine the implementation of the base and to determine the flatness. First, set the height of the whole room, and only after that — the individual sections. It will show the curvature, how thick it will be necessary to perform a screed haydite. After that he is preparing a solution for, to quality would be to align the floor with the help of expanded clay. 90003 90002 In the prepared container or bath backfilled pellets. As for the amount of water, then it should be about half a palm over, than the level of expanded clay.Due to the porous structure of the material used, water in the required amount is absorbed into. Stir the resulting mixture, it is necessary to follow the change in hue. Once he changed, It can be added, depending on the proportions of cement and sand. Floor screed with expanded clay and cement obtained high quality. 90003 90002 There are some subtleties, how to fill floor screed with expanded clay. The prepared solution was spread evenly over the surface between beacons. Drying should be carried out during the first two days.If necessary, then poured another tie layer or finishing is carried out. All will depend on the requirements and the choice of the flooring planks for. 90003 90002 When it is difficult to find an answer, how to pour the floors in the apartment with self-expanded clay, preparing a solution of, it is best to contact the store for the purchase of ready-mix. They are called rovniteli. Alignment floor using expanded clay in the finished mixture allows to bring the level of roughness, reaching the 30 cm.In addition, the screed drying time is slightly less time, than regular claydite. Consequently, This option will be profitable with a limited amount of time. 90003 90002 Appeal to allow specialists to get an answer, how to pour the floor with expanded clay, if there is no such experience. can be carried out any kind of self-pouring, not to spend money on the challenge of building teams. 90003 90004 dry screed 90005 90002 Floor screed with expanded clay may be framed and dry method. And this is the way to recently in great demand and interest among the apartment owners.Its essence lies in the fact, filling expanded clay that occurs at lined with polyethylene film, after which the plates are stacked GOLS. some deem, that it is very easy. But there are subtleties, how to align the floor expanded clay. There is a sequence of actions in this case ,: 90003 90036 90009 Surface preparation for subsequent filling, which is laid film, Employee waterproofing layer. Sunset each subsequent row polyethylene should generally be 15-20 cm. We can not forget about the overlap on the wall, about 6-10 cm.further unnecessary fragments very easily removed and are cut. 90010 90009 In the joints with the walls stacked damper tape. 90010 90009 Next is the installation of beacons along the marked marking indoors. There are several options for the procedure. Each able to select the most suitable option. If a beacon is filled with mortar mix, until the next stage of the work it has to dry completely. 90010 90009 It is worth noting, that expanded clay for dry floor screed fraction may have a completely different.All will depend on the selected floor covering, as well as the conditions of the casting. In any case, the granules must be backfilled portions. set profiles (beacons) then you should not sag. It all checked. 90010 90009 To ram expanded clay used polyurethane grater. 90010 90009 Aligning the surface of the level of, stacking sheet material produced. As for layers, the two layers is generally recommended for reliability and durability. Fastening sheets GOLS is carried out not only adhesive therebetween, but additionally and screws.It is very important to perform in the event, if the very thin sheets purchased. 90010 90009 It occurs sealing putty joints available. If there is a need, it is arranged an additional waterproofing layer. For this fit cover sheets GOLS bitumastic. 90010 90009 All protruding elements, which do not have any good, You must be cut. This applies to plastic film and tape damper. 90010 90047 90002 When all actions are organized and implemented, You can think about, to carry out finishing. 90003 90002 Fill the floor with expanded clay with your hands dry method has many advantages.The result is a really smooth surface without defects, insofar as the technology. Each square meter of floor space is able to withstand approximately 500 kg. Which significantly differs from the usual screed — a complete lack of possible cracks, subsidence, chips and other negative manifestations. 90003 90002 As part of the «pie» without harmful substances to human health. The air no volatile substances do not fall. Once the installation is completed, you can immediately start all subsequent actions.No need to wait for drying the surface for a long time. A room with a large area team of experts may be executed within a few hours. 90003 90002 In addition to receiving a warm floor, even without the system, having a similar name, We get excellent sound insulation effect. 90003 90002 After studying all these points, is not the question arises, how to make a screed in the apartment with expanded clay. Main observe clearly the technology of creating such a surface. Having decking flooring, the surface will remain perfectly flat and is able to serve for a long time.And that no matter, what kind of a way to align with the help of expanded clay is selected. 90003 90002 90127 90128 90003 90002 Video: 90003 90002 90133 90128 90003 90002 Video: 90003 90002 90139 90128 90003 90002 Video: 90003 90002 90145 90128 90003 90002 Video: 90003 .90000 Insulation Materials 90001 By: Jennifer Gray — Updated: 2 Apr 2019 | * Discuss 90002 Insulation is a key component of sustainable building design. A well insulated home reduces energy bills by keeping warm in the winter and cool in the summer, and this in turn cuts down carbon emissions linked to global climate change. 90003 90002 In terms of energy efficiency, investing in high levels of insulation materials for your home is more cost-effective than investing in expensive heating technologies.It is worth taking the time to choose the right materials in the context of whole building design. 90003 90002 Insulation materials are used in roofs, walls and floors. Solid wall structures such as stone, cob and adobe can not be insulated, but they have good thermal mass to compensate. Timber frame homes need wall insulation in the form of batts (pre-cut sections that are designed to fit between stud walls), rolls or boards. Other types of construction such as brick or concrete insulate with spray foam, loose fill or rolls.It is far easier and cheaper to install insulation in the walls and floors of a new build home, than to retrofit an existing home. However, insulating roofs is easily achieved in any home using rolls or bags of loose fill. 90003 90002 Insulation materials work by resisting heat flow, measured by an R-value (the higher the R-value, the greater the insulation). This R-value varies according to material type, density and thickness, and is affected by thermal bridging, unwanted heat flow that occurs at joists, studs and rafter beams.90003 90010 Conventional Insulation 90011 Conventional insulation materials are made from petrochemicals and include: fibreglass, mineral wool, polystyrene, polyurethane foam, and multi-foils. These materials are widely used because not only are they inexpensive to buy and install, but there is an assumption from the building industry that their performance ability is higher than the natural alternatives. On the downside, almost all conventional insulation materials contain a wide range of chemical fire retardants, adhesives and other additives, and the embodied energy in the manufacturing process is very high.90010 Natural Insulation Materials 90011 The green alternative to synthetic insulation is natural insulation. There are many different types available, including: 90010 Sheep’s Wool 90011 This material usually needs to be treated with chemicals to prevent mite infestation and reduce fire risk, although some natural builders use it untreated with success. It has very low embodied energy (unless it is imported) and performs exceptionally well as an insulation material. Thermafleece is the most common commercial brand available.90010 Flax and Hemp 90011 Natural plant fibres that are available in batts and rolls, and typically contain borates that act as a fungicide, insecticide and fire retardant. Potato starch is added to flax as a binder. Both materials have low embodied energy and are often combined in the same product. Examples include Isonat and Flax 100. 90010 Cellulose 90011 A recycled product made from newsprint and other cellulose fibre. It is one of the most favoured materials of natural builders because it can be blown into cavity walls, floors and roofs; used as a loose fill; and is also available in quilts, boards and batts.Like hemp and flax it contains borate as an additive. Products include: Warmcell and Ecocel. 90010 Wood Fibre 90011 Made from wood chips that have been compressed into boards or batts using water or natural resins as a binder. It has very low embodied energy and uses by-products from the forestry industry. Examples include: Pavatex, Thermowall and Homatherm. 90010 Expanded Clay Aggregate 90011 These are small fired clay pellets that expand at very high temperatures to become lightweight, porous and weight-bearing.They can be used in foundations as both an insulator and aggregate. They have excellent thermal insulation properties, but high embodied energy. 90010 Insulating for a Better Environment 90011 Natural insulation products have many advantages over conventional materials. They are low impact, made from renewable, organic resources and have low embodied energy. They can be reused and recycled, and are fully biodegradable. They are non-toxic, allergen-free and can be safely handled and installed. They also allow for a buildings to breathe by regulating humidity through their absorbent properties, and reducing problems of condensation.This keeps the indoor environment comfortable and protects any timber structures from rot. 90002 Unfortunately, natural insulation materials are currently up to four times more expensive than conventional materials, which can be prohibitive to builders, architects and developers. But the environmental and health benefits of natural insulation materials far outweigh their costs, and growing consumer demand combined with government regulation, and rising oil prices will inevitably drive prices down.Despite the high price, natural insulation is an energy-efficient, healthy and sustainable choice for a better indoor and outdoor environment. 90003 90002 You might also like … 90003 90002 Share Your Story, Join the Discussion or Seek Advice .. 90003 it is really interesting however you can improve this site by adding more images related to this project. 90002 saman — 4-Mar-19 @ 11:52 AM 90003 Good afternoon, I have a building refurbishment and repair project, to bring new life to a stone built Old primary school.It is constructed of thick stone walls about 600 mm thick, with render externally plus internal lime plaster. The roof is traditional slate, and originally had an exposed lathe and plaster ceiling fixed directly to the rafters.it does not appear to have any roof felt. I am looking for guidance on insulating and repairing the internal surface of the roof, hopefully to reinstate the original appearance of the sloping ceiling at rafter level and exposed King trusses. Any information on details for insulating andrefinishing the roof internally would be appreciated.The slating is in good condition so taking roof coverings off and refining would not be an option. I do not like the solution of lining with Kingspan or celotex, andam thinking thata’green ‘and traditional breathable approach would be better. Due to extensions very little of the existing stone exterior wall is exposed so I think heat losses from walls are not going to be major in comparison to the roof. As it’s in Wales, I have to comply with the BR forWales which are a little more onerous. The other issue is to deal with the floors.One area needs a solid floor solution as ventilation to the suspended floor is impossible to achieve.Looking at foamed glass? Any guidance would be appreciated.

I am looking for guidance on insulating and repairing the internal surface of the roof, hopefully to reinstate the original appearance of the sloping ceiling at rafter level and exposed King trusses. Any information on details for insulating andrefinishing the roof internally would be appreciated.The slating is in good condition so taking roof coverings off and refining would not be an option.I do not like the solution of lining with Kingspan or celotex, andam thinking thata’green ‘and traditional breathable approach would be better. Due to extensions very little of the existing stone exterior wall is exposed so I think heat losses from walls are not going to be major in comparison to the roof. As it’s in Wales, I have to comply with the BR forWales which are a little more onerous. The other issue is to deal with the floors.One area needs a solid floor solution as ventilation to the suspended floor is impossible to achieve.Looking at foamed glass? Any guidance would be appreciated.

We’re conjuring up lovely pictures of a ragstone cottage with oak windows and porches here! Is that what your property is like. First of all is the wall visible between the porch or is it a solid oak panel? Not really clear from your question sorry.90002 SustainableBuild — 9-Jul-14 @ 11:07 AM 90003 Is there a way of insulating between ragstone and oak? We have an oak porch which is attached to a ragstone wall, however, there are small gaps between the ragstone and the porch which make the porch chilly in winter. 90002 karendeburca — 8-Jul-14 @ 10:42 PM 90003 @Mack. Yes they do. Rice hulls have been used in several green build projects over in the states. They have the advantage of being lightweight, good for transportation and once packed into bags, hold their shape & have quite good load bearing properties.90002 SustainableBuild — 11-Jun-14 @ 12:30 PM 90003 i would like to know if rice hulls have insulating properties? 90002 mack — 11-Jun-14 @ 11:39 AM 90003 Earthing material manufacturer plays a crucial role in installation and distribution of High Tension and Low tension power supply.

Leca has approximately round shape externally or potato shape due to circular movement on rotary kiln production line. 90079 LECA is usually produced from 0.1 mm up to 25 mm and supplied in various rang sizes, which some of the commons grades are (0-4) mm, (4-10) mm, (10-25) mm and 0-25 mm which has 510, 330, 250 and 280 kg / m3 average density.LECA boulder is a the bigger size of LECA with 100-500 mm size and 500 kg / m3 density. Some of the advantages of clay aggregate are: lightness, thermal insulation by low conductivity coefficient, soundproofing by high acoustic resistance, moisture impermeable, incompressible under permanent pressure and gravity loads, non-decomposition against severe condition, fire resistant, Ph of nearly 7, freezing and melting resistance, easy movement and transportation, lightweight backfill and finishing, reduction of construction dead load and earthquake lateral load, perfect sweet soil for plants, best material for drainage and filtration.90080 90079 Its Lightness is due to the multi-separated air spaces which exist inside and among the aggregates, density of aggregates, depending on the size, is fluctuated from 380 to 710 kg / m3. Its Thermal conductivity coefficient for is about 0.09 to 90080 90079 Clay aggregates are available in various sizes. Four usual gradations are 0-4mm, 4-10mm, 10-25mm and 0-25mm. Their bulk dried density and their applications for different gradations are: 90080 90079 For use in Light Weight Concrete, light weight block, Prefabricated Panels & Slabs.Light Filler, Leca Mortar and Water Purification system.
