General info

Why is it perfect for experts?


B1 Foam complies with building class standard B1, has a high insulation value both thermally and acoustically and meets noise standards up to 57 db. B1 Foam adheres excellently to most materials and has a high form stability; no shrinkage or post-expansion.

Why use B1 Foam ?

  • smoke-resistant sealant between walls, floors and ceilings.
  • optimizing insulation in cooling technology.
  • assembling doors, frames, panels, windows, ... in plastic, aluminum, wood, metal, ....
  • thermal insulation of building components and pipes.
  • foaming of connecting joints between, among other things, window frames, roof windows and brickwork.


  • Shake before use.
  • Apply on pure and stable surface.
  • Protect adjacent surfaces.

Moistening the substrate promotes adhesion and accelerates curing. Moistening between the layers and on the top layer also accelerates the curing and increases the build-up capacity. Lower foam efficiency at low temperatures and freezing temperatures. For the use of the gun see Foam gun. Clamp the bus with every transport.
