Promat offers a wide range of products (bags, pastes, sealants and liquid coatings, necklaces, bricks, stoppers, sheaths, intumescent strips, etc.) which, thanks to their intumescent power, ensure fire performance on the surface of the hoppers ( expansion in contact with heat from 150 ° C).
They can reach up to 20 times their initial volume and thus seal the space created by the destruction of the burnt elements.
These products allow the realization of qualified caulking systems by P.-V. Efectis and CSTB laboratories, for sail, slab and light partition configurations.
