That a certain type of grey cellular plastic has better insulation ability than white is something that we can all agree on. Lambda value is what it is also called, although you might as well call it added value. Because with an increased lambda value comes thinner insulation boards, savings in volume, lower transportation costs and most importantly; reduced energy consumption. EPS Grey has around 20% better insulation value than traditional white has. The better insulation value is achieved through a different type of raw material that has the addition of graphite.
Cellular plastic can be used to insulate a house from the foundation to roof, as frost insulation, cast in a plate on the ground etc.
The drainage board allows the moisture from inside the house to escape, while it prevents the moisture from outside to get in. The foundation becomes dry and warm, creating a better indoor climate.
EPS GREY have many advantages as roof insulation. Not only due to it's insulation capacity, but also thanks to it's low weight. Forget about the usual problems with cold bridges!
