Adding home insulation is one of the most cost-effective upgrades you can make to your property. Insulation keeps heat in during the winter and outside air out, which can reduce energy bills by up to 40%. In addition, it helps prevent the buildup of mould in your home and can even improve resale value.
The main function of home insulation is to slow the movement of heat from room to room. Without it, heating and cooling are continually used to try and heat or cool specific rooms in the house – leading to higher electricity and domestic fuel oil bills.
Insulation creates a barrier that stops heat from escaping during the winter and stopping hot air from creeping into your house during summer. The materials used in most home insulation are able to stop thermal energy flow both ways, which is why it can be so effective.
There are various types of insulation available on the market, each designed for different applications. Some of the most commonly used are blanket batts or rolls. Often made of fiberglass, they are designed to fit into the standard space between wall studs or attic rafters and floor joists.
Another common form of home insulation is foam. This is usually spray on, which can fill the gaps in between studs and other hard to reach areas. Other types of home insulation include mineral wool, cotton and sheep’s wool. They are usually not as thick as blanket batts and rolls, so are best for use in the attic and other structural spaces within your property.
