Plastic foam insulation has a high R-value, which means high resistance to heat flow. As a result plastic foam insulation, when installed as required, can protect your house from cold air flows and save more energy than other insulation types.
There are several forms plastic foam insulation comes in – as a liquid in smaller aerosol bottles or in bigger pressure sprayers and also as panels or boards, which are produced at a factory. Another way is to install plastic foam as beads – they are blown in the wall cavities or between blocks or boards to create insulation.
In case of plastic foam insulation which requires a pressure sprayer for installation, it is recommended to hire a professional to install your insulation with specific materials and equipment.
Plastic foam insulation is used mainly in places where it is difficult to use other types of insulation – e.g. in walls and cavities where it is not easy to get to, because liquid plastic foam is installed as liquid which expands after a little while filling all the gaps and cavities on the way.
Boards can be thicker when used in ceilings and roofs and thinner when used in walls.
All types of plastic foam insulation must be protected from the sun as it may damage the insulation after a while.
