Material

DELTA®-ROOF is engineered with spun-fiber material for excellent physical properties, combined with an inner waterproof layer, and reinforcement grid.

Characteristics

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.

DELTA®-ROOF has been designed for ventilated pitched roofs with sheathing boards. Its relatively water 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.

Designed for ventilated pitched roofs with sheathing boards , DELTA®-ROOF can be laid directly under all conventional roof claddings.

Application

The surface texture provides high abrasion resistance, prevents slipping and makes DELTA®-ROOF very user-friendly - great for safe installation. In comparison to bitumen and asphalt saturated sheathing membranes DELTA®-ROOF is pleasantly lightweight. The material is available in rolls 1.5m wide and 50m long, ensuring fast and easy installation.
