Secure payment with:
is a non-vapour retardant roof underlay without acrylate adhesive strips for installation directly on the thermal insulation or the wood sheathing. The monolithic membrane guarantees high UVresistance and extremely high resistance to the penetration of rain. Vapour transmission through the functional film is no longer a result of capillary conduction but transport is active from the interior to the exterior through the non-porous membrane. Water-tightness and UV-resistance are therefore retained even under the influence of wood preservative, chain saw oil or resin.
FIELD OF APPLICATION
for vented pitched roofs
high quality protection for wood and insulation
for installation directly on thermal insulation or wood sheathing
