FIXBLOCK: special Nylon clamps reinforced with EPDM suction seals.
A Poliform Lucernari invention born from the need to unite and solve problems created by xing with clips (clamps). The rst is the sealing impact, which exce- eds 5 cm creating a greater pressure on the surface. Each point is 300 kg shear resistant. The design of the suction seal guarantees outstanding tightness as the gasket creates an internal and external seal. The skylight remains rmly anchored to the substrate so any overturning does not move the dome.
The impact on the surface of the dome with the EPDM suction cup provides ela- sticity to the normal expansions of polycarbonate. Installation is fast and easy, also allowing changes of position. The nickel-plated steel screw remains protected from the elements as it is housed internally.
