DELTA®-ROOF
The reinforced roof underlayment that adds extra protection and value to your roof. This 4-layer material - designed to be installed under asphalt shingles - is totally waterproof, wind resistant, super tough, and easy to install.
DELTA®-ROOF combines excellent material properties to provide superior protection to the roof against rainwater, snow, wind, and dust. The membrane is lightweight and easy to install, and at the same time far more resilient than conventional asphalt saturated base sheet. Its strong reinforcement mesh makes this underlayment extremely tear resistant, even when exposed to high winds.
DELTA®-ROOF has been designed to provide ultimate protection to ventilated pitched roofs with asphalt shingles. Its low vapor permeability helps to prevent buckling of asphalt shingles caused by solar driven moisture that would usually cause the sheeting boards to swell and expand.
Outside layers made from spun-bonded Polypropylene for excellent physical properties, combined with an inner waterproof polymer layer and reinforcement grid.
The surface texture provides high abrasion resistance, prevents slipping and makes DELTA®-ROOF very user-friendly. In comparison to bitumen and asphalt saturated sheathing membranes DELTA®-ROOF is pleasantly lightweight. The material is available in rolls 4'11" ft (1.5 m) wide and 164 ft (50 m) long, ensuring fast and easy installation.
