Wall Thermal Insulation Materials

The most common types of materials used for loose fill insulation include cellulose fiberglass and mineral rock or slag wool.

Wall thermal insulation materials.

The most common insulation materials are fiberglass cellulose and foam. Fire resistant treated insulation is made with 85 recycled material that meets a class 1 fire rating to protect your home and give you more time to evacuate. Greenfiber blow in cellulose insulation fills gaps and voids to create an energy saving thermal blanket that can lower heating and cooling costs by 25 and reduce sound power by 60. Building insulation materials are the building materials which form the thermal envelope of a building or otherwise reduce heat transfer.

Expanded polystyrene eps has a k value of around 0 033 w m k. Because of how it is made by effectively weaving fine strands of glass into an insulation material fiberglass is able to minimize heat transfer. In order to accomplish small gas cell formation in man made thermal insulation glass and polymer materials can be used to trap air in a foam like structure. The main downside of fiberglass is the danger of handling it.

Insulation r values vary based on the type thickness and density of the insulation material. The blue plastic on the central building is the vapour barrier for the thermal wall insulation before the exterior cladding has been fixed. Typically a higher insulation r rating means better climate control and better energy efficiency for your home.

You can mix insulation materials and types. Cellulose is primarily made from recycled newsprint. Mother s researchers show homesteaders how to make and install your own insulation creating a low cost good quality insulation using newspapers and a farm type hammermill. An r value tells you how well a type of insulation can keep heat from leaving or entering your home.

Most fiberglass products contain 40 to 60 recycled glass. Best seller owens corning foamular 250 2 in. The thermal conductivity k value is the ability of a material to conduct heat. Hence the lower the k value the better the material is for insulation.
