Perfimur flashing cover
PERFIMUR cover panels are manufactured through a continuous manufacturing process using the most modern technologies. The sandwich panel is formed by an outlined metallic face wall, inside which a core of polyurethane foam works as a thermal insulating. This provides it with a great solidity thanks to the excellent adherence of polyurethane to metallic parameters, due to the special treatment that steel sheet received.
This panel fastening is made through screws hidden by the flashing, created for such purposes. Besides, this flashing guarantees full water-resistance because it avoids the entrance of water, even by capillarity.
PERFIMUR uses high-quality pre-lacquered steels. Steel galvanised sheet Z225 by zinc immersion (Sendzimir process) SIN EN 1 0142 and DX51D quality of 0.6 mm thickness and pre-lacquering covering depending on needs (polyester, Plastisol, PVDF, etc.). It is also possible to use other sheet thickness following a previous study.
Minimum roof pitch of 5% for covers without flap. Minimum 7% for covers with flap.
