Sprayed Foam Home Insulation – Turn Your Home Energy Smart
Sprayed Foam home insulation product is a foam based insulation product that is applied to insulating cavity walls, floors or roofs. As this insulation product is sprayed to the openings in the area, it expands to create the insulation barrier. This foam insulation material is a chemical insulation product being made of polyurethane. The polyurethane comprises a chemical formulation of multi-ingredient chemicals. Apart from this main multi-ingredient chemical composition, sprayed foam insulation also contains other additives like fire retardants as well as colours too, often.
Apart from providing home insulation, spray foam based insulation materials are good air sealing. The air sealing treatment can be applied to several places of the house where small openings allow air passing such as cavities in the wall, cavities in the ceilings. The foam product can be sprayed using a special equipment to the targeted holes in the walls or ceilings. On spraying, the chemical formulation swells to cover up all the corners and crannies in the area. While application, the spare materials must be scraped off the wall pr other spaces to form uniform cavity insulation and ensure an effective air sealing guard to prevent air and heat conduct.
Advantages of Spray Foam Home Insulation
There are several advantages of sprayed foam home insulation materials. First of all, sprayed foam home insulation is an easy to apply insulation option that fills up the targeted nooks in the walls completely providing it air sealing protection to stop further air passing. This insulation material is known to reduce air infiltration and air circulation that allows heat transfer through gaps in the walls. The sprayed foam insulation also acts as a vapour barrier. However, the installer must consult with the local building department whether the building needs a vapour barrier. As the foam materials expand well in the tight areas, it makes a good insulation for steel framing outlets or forming insulation around outlets.
Apart from polyurethane chemical composition, the spray foam home insulation products can be combined with other insulation materials such as fibreglass batt in order to reduce cost. The layer 1000 of foam based insulation mixed with other materials performs better air sealing thus turning the home more energy smart within lesser budget. Some home insulation contractors use this foam product as a 1′ inch layer of closed cell foam and then tops the layer with fibreglass batt insulation for increasing performance of the insulation.
