Spray polyurethane foam roofing

Spray polyurethane foam (SPF) roofing systems are composed of an in situ insulation layer made of spray polyurethane foam and a surface protection layer. The systems are used for roofs that are walk-on only for repair and maintenance purposes.

Regulatory framework

DIBt grants general construction technique permits (aBG) in this work area.

Regarding design and execution, the Administrative Provisions – Technical Building Rules of the federal states (VV TB) must be observed. Cf. the common model MVV TB, in particular Section A 6 (Heat retention).
