There are many ways to skin a cat, and almost as many ways to keep heat from entering or escaping your home. Different materials offer different things – some are easier to install in certain circumstances, some are better for retrofits, some simply perform far better than others and some have added soundproofing benefits that may tip the scales in their favour.
Cellulose insulation is made from plant fibres, and is used to insulate wall and roof cavities. Cellulose insulation does an excellent job of controlling heat at a good price, and is highly versatile.
Glass wool insulation
Glass wool is made from fibreglass, and is available either as rolls of insulation, or as batts or blanketing. Glass wool is relatively inexpensive, and as a result it’s sometimes layered for improved insulating performance.
Reflective foil insulation
Foil-type insulation is reflective insulation, designed to prevent radiated heat from entering your home. This type of insulation is most often used in warmer climates to keep heat out of a house.
