Tear resistant roofing membrane for slightly inclined flat roofs. Can be welded with hot air or solvent welding agent.
In combination with the DELTA® system components the roofing membrane enables the creation of a rain-proof and watertight sub-roof in accordance with ZVDH regulations.
DELTA®-ALPINA can be laid quickly and safely. Trapezoid counter battens are not required.
The product is laid onto a casing or comparable pressure resistant surface. The roll must be aligned without creasing. The roll is secured in the area of the upper and side overlaps using concealed staples or clout nails.
Welding can be undertaken homogeneously with both DELTA®-ALPINA QSM (welding seam width min. 4 cm) and hot air (welding seam width min. 2 cm. ÖNORM B 4119 min. 4 cm).
