Its elasticity and extreme tear resistance makes the material especially easy to fit and offers a high level of installation safety.
The double adhesive strips mean that the material can be simply rotated during the laying process.
The result: minimal offcuts, maXXimum cost savings, minimal time requirement – maXXimum satisfaction
Also suitable for use as façade sheeting behind enclosed joints!
New from 01/01/2023!
DELTA®-MAXX PLUS is the solution for fully-insulated pitched roofs and meets the requirements of ZVDH product data sheets UDB-A and USB-A. The sheeting can also be used as temporary roofing and as façade membrane behind ventilated cladding with closed joints as well as for wooden sheathing.
The two integrated adhesive strips on the underside enable especially efficient and economical laying of the pitched roof membrane. The underlay membrane is rolled out parallel to the eaves and can be laid beginning from either right or left. The sheeting can be rotated 180 degrees and laid in the opposite direction. A tight fit in areas such as hips and coving avoids unnecessary offcuts, as fitting can continue immediately with the angled-cut roll.
After laying, simply remove the backing strips, press the edges into place, done!
The adhesive strips immediately adhere and are resistant to wind. The integrated self-adhesive edges and the smoothed rear side of the non-woven fabric mean that DELTA®-MAXX PLUS can be laid quickly. The grid structure on the top side serves as a perfect cutting guide.
More information on laying can be found in our laying instructions for sarking, underlay and sheathing sheeting.
