VENTIA METAL roof membrane with a mat

Ventia Metal 430 ^g/m2 roof membrane

Ventia Metal is a three-layer, highly vapor-permeable roof membrane with a polypropylene spacer mat designed as an insurance waterproofing for insulated pitched roofs under metal roofing laid directly on solid boarding. It perfectly drains moisture from the underside of the roofing while providing a ventilation gap. The basis of the product is a roofing membrane with improved strength parameters, which is not subject to mechanical damage, bringing considerable comfort during installation. The membrane is printed for easy installation. The use of Ventia will extend the life of the roof and attic.

• TT version, with two adhesive strips (on request)

PAGE

Ventia Metal is installed on a hard, flat, clean and dry substrate. It is laid directly on the boarding so as not to cause the membrane to ripple. The print is directed towards the roofing, i.e. upwards. Installation begins from the bottom of the roof (at the eaves) and proceeds upward (toward the ridge). The overlap of the strips is at least 10 cm, see the imprint on the membrane.

Material:

Polypropylene fibers bonded with polypropylene active film; drainage spacer on the outside.
