A selection of insulation materials can help insulate buildings. All of these are based on the principles of thermal insulation.
Materials used to reduce heat transfer by conduction, radiation or convection are used in various combinations to achieve the desired results (usually hygrothermal comfort with reduced energy consumption).
Choice of insulating materials
The choice and degree of insulation is based on a number of factors:
Typically, a combination of materials are necessary to achieve an optimal solution for a building over a range of climatic conditions. There are also some products that combine different types of insulation in a single product. It is a great idea.
Commercial systems used for insulation
Contenido
El aislamiento puede ser instalado en una serie de formas:.
Structural
Board insulation is the most common at the moment, although it can generally allow for more heat transfer than other options. There are other options that work better for sealing wall cavities completely. The plates can reduce heat loss through walls, beams and others due to thermal bridges due to conduction.
Rigid panels
Panel de aislamiento rígido se fabrica a partir de materiales fibrosos (fibra de vidrio, roca y lana de escoria")) o de plástico espuma. Algunas veces son vendidos en las secciones diseñados para encajar perfectamente en este tipo de cavidades de pared. Cuando se vende de esta manera, se les llama "batts", y vienen en diferentes grosores para que coincida con la profundidad de la pared de caries, por ejemplo, aprox. 5 ½ pulgadas a la altura de 2 x 6 pared cavidad.
Cuando paneles rígidos son más utilizadas:.

Importante # 1: Si aislar las bases con paneles rígidos, pero que dejen de utilizar paneles rígidos, donde el revestimiento se inicia, entonces usted debe instalar entre la parte destellante en la parte inferior curso de revestimiento y el borde superior de los paneles rígidos, para evitar que el agua de filtrarse detrás de los paneles.
Importante # 2: Cuando el aislante exterior fundación, deberá instalar los paneles rígidos escalonada en dos capas, y colmar las lagunas en las costuras, con un spray de espuma "Aislamiento térmico"), para mantener la humedad de penetrar desde el exterior. Sin embargo, cuando aislante entre el revestimiento y revestimiento, usted debe dejar ligero diferencias entre los paneles rígidos para permitir que la humedad de escapar de la parte exterior del revestimiento.
More about rigid polystyrene cellular panels
There are many types of rigid polystyrene cell phones (RCPS). Styrofoam is simply the Dow Chemical brand name, and does not refer to any particular type of RCPS. Some polystyrene uses up to 50% recycled resin, including post-consumer plastic. Several states have banned polystyrene that uses CFCs as blowing agents.
Fiberglass plates and blankets
Las placas son precortadas, mientras que las mantas están disponibles en rollos. Comprimir el material reduce su eficacia. Cortarlo para acomodar las cajas de electricidad y otras obstrucciones permite que el aire encuentre un camino libre para circular a través de la cavidad de la pared. Se pueden instalar placas en dos capas a través del piso de un ático sin terminar, perpendiculares entre sí, para una mayor efectividad en la prevención de un puente térmico. Las mantas pueden cubrir vigas y postes, así como el espacio entre ellos. Las placas pueden ser un reto y una tarea desagradable para instalar debajo de los pisos entre las vigas; el uso de correas, o grapas de tela o malla de alambre que atraviesen las vigas, las puede sostener.
Los espacios entre placas (desvíos) se pueden convertir en espacios de infiltración de aire o condensación (ambos de los cuales reducen la eficacia del aislamiento) y requiere una estricta atención durante la instalación. De la misma manera una cuidadosa climatización e instalación de barreras de vapor") es necesaria para garantizar que las placas tengan un rendimiento óptimo. También se puede reducir la infiltración de aire mediante la adición de una capa de celulosa suelta en la parte superior del material.

Natural fiber insulations (about 0.04 W/mK), treated with low toxicity and insect fire retardants, are available in Europe: cotton, hemp, linen, coconut, and wool, often mixed with polyester fibers and light wood fiber, and cellulose (often with polyolefin).
Plates as the residential insulating option
Historically, fiberglass boards became the preferred choice for home construction at the turn of the century, it is useful to understand how this evolved, as there are no inherent advantages. [Commercial and industrial construction typically does not use plates.] In the 1970s in response to oil price shocks, many US state governments sought to cut off home heating oil. And it led to the building code's increasing use of insulation for all new housing needs. At the same time, Owens Corning' fiberglass lobbied intensely to convince building officials who wrote and separately administered the four building codes used in the U.S. It also aimed to eliminate other types of housing insulating material (such as polyurethane) over safety or hazard. The result was that Owens Corning successfully lobbied for mandatory 2" x 6" (50 x 150 mm) fiberglass insulated wall construction. It suits lumber merchants as well as it suits Owens Corning. Then, taking into account the prevalence of non-wind proof cladding materials, and the prevalence of sleet (wind ice) during the winters of the northern states, the need was created to ensure the entire 150mm of fiberglass remained ice free and dry at all times. Building code officials also made it mandatory to secure and seal wind- and sleet-proof plywood siding in connection with all siding. It adapted the plywood industry very well - which in turn led to the North American development of its now massive oriented strand board (OSB) industry.
Other insulation materials present advantages in terms of stopping air, moisture migration, and recycling so sustainability is not found in fiberglass batts.
