Perfimur non-flashing cover

The PERFIMUR sandwich panel for non-flashing cover is formed by a double outlined metallic sidewall, inside which a core of polyurethane foam works as a thermal insulating. This provides it with a great solidity thanks to the excellent polyurethane adherence to metallic parameters, due to the special treatment that steel sheet received and the quality of the raw materials used in manufacturing.

This panel is fixed by flapping two adjacent panels in their crest. Through a corrugated washer of EPDM especially designed for such purposes, full water-resistance is guaranteed from the fastening made with self-tapping screws whose head do not cover any flashing and where a plastic cover of the same colour can be placed. A 0.6 mm polyester sheet can be placed in the inner layer for sheets that will be used in aggressive environments such as farms or that require antibacterial protection.
PERFIMUR uses high-quality pre-lacquered steels. Steel galvanised sheet Z225 by zinc immersion (Sendzimir process) S/N EN 1 0142 and DX51D quality of 0.5 mm thickness and pre-lacquering covering depending on needs (polyester, Plastisol, PVDF, etc.). It is also possible to manufacture using other sheet thickness following a previous study.
Minimum roof pitch of 5% for covers without flap. Minimum 7% for covers with flap.
