Pipewrap
PIPEWRAP is Marvon’s intumescent seal realized to guarantee fire resistance up to EI 240 of isolated combustible and incombustible pipes.
PIPEWRAP is composed of a graphite-based thermo-expanding material that reacts, in case of fire, sealing the crossing.
Application field
The PIPEWRAP seal must be embedded inside the support: flexible wall (plasterboard), rigid wall (masonry, concrete or aerated concrete), rigid floor (concrete, aerated concrete).
It has a fire resistance up to El 240 classified according to EN 13501-2 for:
- Combustible pipes (PVC-U, PVC-C,PE HD, PE, ABS, SAN+PVC, PP, PE-RT, PE-RT/AL/PE-RT, PE-X, PE-X/AL/PE-X, PP-R, PP-R/AL/PP-R, PP-R/PP-R-GF/PP-R).
- Combustible soundproof pipes (es. Valsir Triplus®, Valsir Silere®, Valsir PP3, Valsir Blackfire®)
- Multilayer pipes (es. Valsir Mixal®, Valsir Pexal®)
- Incombustible pipes insulated with combustible insulation
- Flexible wall minimum 125 mm
- Floor and rigid wall minimum thickness 150 mm
