SpanIzol A Eco (Wind-waterproofing)

Spanizol A - Waterproofing windproof and vapor-permeable membrane

Spanizol A is a polypropylene nonwoven fabric (spunbond). Windproof single-layer membrane is designed for wind and moisture protection under siding (cladding of building walls), in the heat-insulated roofs with angle of inclination over 35° of the various coatings: metal tiles, natural tiles, soft bituminous tiles, profiled sheets, etc.

The membrane retains heat and is resistant to UV radiation. It has water resistance sufficient to protect insulation and other internal elements of wall structures from atmospheric precipitation penetrating under the outer cladding, while being vapor-permeable material, therefore it does not prevent water vapor from escaping from insulation into the ventilated gap. The strength and quality of the material is resistant to mechanical stress at installation stage and during operation.

In the structures of interior walls (interior partitions) Spanizol A is used to prevent penetration of fibrous insulant particles into the interior of the building. Subject to all the requirements for installation, the use of Spanizol A windproof membrane allows you to preserve thermal insulation properties of insulant and extend service life of the structures.
