Reflective Foil Insulation!

Define Reflective Foil Insulation:
Reflective foil insulation is a kind of insulation that works by primarily reflecting the heat away. It absorbs and emits only a small amount of heat. It works best when the reflective surface remains shiny and there is a “cushion” of air at least 20mm between the insulation and the wall or ceiling. Essentially, reflective foil insulation stops the movement of heat.

Importance of the R Value:
The R value plays an important measurement in insulation. The R value measures the insulating product’s resistance to heat transfer and is a guide to how the product performs as a heat insulator. The higher the R value, the better the insulation is at stopping heat from flowing into or out of the home. When it comes to reflective foil insulation, the R value refers to the total heat resistant of the roof or wall after the insulation has been installed. So, as well as the insulation itself, the R value also includes the materials used in the roof or wall and the air spaces.
