A warm roof system on which a second insulation layer is placed, consisting of foam panels
of extruded polystyrene, following the principle of the inverted roof. This system helps to improve thermal insulation
and inertia, whilst at the same time ensuring better mechanical and thermal protection of the waterproofing material.
Durability
of 50 years can be expected with the ‘Long Life’ design, in which particular care is given to certain points and all the
surfaces of the waterproof membrane are protected, both horizontally and vertically.
