| The tough roofing underlay that adds extra protection and value to your roof. This 4-layer material - designed to be installed on roof sheathing - is totally waterproof, wind resistant, supertough, and easy to install.
Material
Spun-fiber material for excellent physical properties, combined with an inner waterproof layer, and reinforcement grid.
Characteristics
DELTAŽ-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.
DELTAŽ-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.
The product can be laid directly under all conventional roof claddings.
Application
The surface texture provides high abrasion resistance, prevents slipping and makes DELTAŽ-ROOF very user-friendly. In comparison to bitumen and asphalt saturated sheathing membranes DELTAŽ-ROOF is pleasantly lightweight. The material is available in rolls 1.5m wide and 50m long, ensuring fast and easy installation.
