Insulation Insulation [pdf 641 KB] Insulation acts as a barrier to heat flow and is essential for keeping your home warm in winter and cool in summer. A well-insulated and well-designed home provides year-round comfort, cutting cooling and heating bills by up to half. This, in turn, reduces greenhouse gas emissions.

What is an Insulator? An insulator is a material or method that restricts the transfer of either heat or electricity. Insulators are used to protect us from the dangerous effects of electricity flowing through conductors. Insulators are materials that have just the opposite effect on the flow of electrons.

Cavity wall insulation costs and savings More than a third of all heat lost from an uninsulated home escapes through the walls, so it shouldn't be a surprise to learn that installing cavity wall insulation is often one of the most cost-effective measures you can undertake to save energy in your home.all insulation acts as a blanket that prevents heat from escaping through the walls of your home. It can also help to stop your home getting too hot in summer. The type of wall insulation you’ll need depends on whether your home has cavity or solid walls. Both types should be installed by a professional installer.

Blown and Sprayed Insulation Blown-in insulation, or blow in insulation, products are competing to bring improved performance per square inch and the least amount of settling over time to the insulation market. Blown-in insulation refers to blowing or spraying insulation product into wall cavities, attics, and floors. Methods vary depending on the form of insulation selected. Loose-Fill Fiberglass In its loose-fill form, fiberglass is made from glass that is blown or spun into fibers. It is installed using a blowing ...

Cavity wall insulation Cavity wall insulation. Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with material that inhibits heat transfer. This immobilises the air within the cavity (air is still the actual insulator), preventing convection, and can substantially reduce space heating costs.

Types of Insulation Insulation R-Value. R-value is the measure of a material's ability to resist heat conduction. The greater the material's R-value, the better it performs as an insulator. All values assigned to insulation are based on specific thicknesses and are usually noted on the packaging.

Top 5 Green Insulation Options Still, others consider insulation green when it's made of natural materials [source: Carter]. Whatever your definition of green, the best way to quantify how well insulation works is by its R-value, which measures its resistance to heat flow and ranges between less than R-1 and R-60. The more the material restricts the flow of heat, the higher its R-value [source: U.S. Department of Energy].
