Reinforced Polythene Building Membranes
Reinforced polythene vapour check
Used with metal profile cladding for Industrial Buildings

New Procheck Vapour Control membrane is a strong reinforced polythene vapour check for use inside insulation in wall and roof construction to prevent warm, moist air from inside the building condensing within the insulation. The reinforced construction resists tears and punctures that can quickly compromise the performance of ordinary building films.

Construction

New Procheck Vapour Control membrane is a strong reinforced polythene vapour check for use inside inside insulation in wall and roof construction to prevent warm, moist air from inside the building condensing within the insulation. The reinforced construction resists tears and punctures that can quickly compromise the performance of ordinary building firms. New Procheck is transparent/translucent and both surfaces have a smooth, gloss appearance.
