Roof Protect Chemical Services The type of hard fiber insulation is used to create a conical insulation system. But not necessarily in the same way as rigid insulation. It consists of cement-like wood fiber planks. That are glued with a layer of foam to create a structural insulation function. This material can be seen in older roof assemblies. But production has ceased in recent years as the insulation of foam panels for supporting decks has developed well.
Other types of hard fibre insulation materials available on the market today include polyurethane, polyethylene and polypropylene, and polystyrene. Which one you choose ultimately depends on the way you use your pitched roof and the size of the roof. The basic decision you have to make when insulating a flat roof is the material. Remember that this process is just as important for insulating an unventilated roof as it is for ventilation. In this case, care must be taken to achieve the corresponding roof pitch by applying the layer of screed directly to the ceiling tile.
