Doerken Delta-Fassade B Rain Shelter

Delta-Fassade B, an innovation from Doerken

The result of many years of development in the Doerken company's research units, the Delta-Fassade B rainscreen is revolutionizing the timber construction market. The flexible product (240 g/m²) combines Euroclass B certified fire-resistant properties (equivalent to M1), compliance with the permeability and mechanical resistance criteria of Unified Technical Document 31.2 and a capacity for endurance against ultraviolet rays, which allows it to be installed in addition to openwork cladding (openwork supported up to 20 mm).

A solution to reduce the number of fire victims

Delta-Fassade B can be used in two situations: on timber-frame building construction sites, as well as during external thermal insulation work, using added cladding.

In response to government objectives to reduce the number of victims of home fires, the implementation of Delta-Fassade B considerably reduces the risk of fire spreading to the buildings concerned.

Exceptional properties

• Fire response certified B (NF EN 13501-1) (equivalent to M1)
• Applicable with ventilated cladding, whether ventilated or openwork, in the latter case possibility of voids reaching 20 mm and opening totaling 20%
• W1 level waterproofing, increased permeability
• Flexibility (240 g/m²), lightness and strength
• Compliance with DTU 31.2 and 41.2
