Tecnobrick
TECNOBRICK is Marvon’s polyurethane sponge intumescent brick designed and developed to ensure fire resistance up to EI 180 of penetration seals on wall and floor according to EN 1366-3.
TECNOBRICK is an easily shaped spongy product suitable to seal holes in different geometries.
When exposed to fire, it expands at 200°C further increasing its volume thanks to the presence of graphite.
Application field
TECNOBRICK can be used on flexible wall (plasterboard), on rigid wall (masonry, concrete or aerated concrete
and on rigid floor (concrete or aerated concrete).
It has a fire resistance up to EI 180 to classified according to EN 13501-2 for:
- Combustible pipes (PVC-U, PVC-C)
- Insulated multilayer pipes
- Insulated incombustible pipes (copper or steel)
- Cable trays and corrugated pipes
- Empty holes
- Ventilation ducts
N.B. The brick is used in case of large crossing and penetration of mixed services. Seal any remaining gap with TECNOGRAPHIT foam.
