Flashing or Non-flashing Agricultural Panel
The Agricultural Sandwich Panel PERFIMUR is manufactured through a continuous production process using the most modern technologies used in farms and breeding centres, responding to the needs of protection against aggressive atmospheres, chemical and bacteriological agents of animal origin. The Agricultural Sandwich Panel is formed by an inner layer made of polyester reinforced by fibreglass and an outer layer made of polyester based (silicone polyester or PVDF) pre-lacquered steel. In the middle, an insulation core made of rigid polyurethane foam is injected and expanded in a controlled manner, giving the sheet a great solidity thanks to the excellent adhesion of polyurethane to metallic parameters and the polyester layer.
Depending on what kind of sheet we are working with, it is fixed through screws hidden by the flashing made for such purposes or through exposed fixing. In both the flashing and non-flashing panel, a full water-resistance is guaranteed because it avoids the entrance of water, even by capillarity.
PERFIMUR uses high-quality pre-lacquered steels. Steel galvanized sheet Z225 by zinc immersion (Sendzimir process), S/N EN1042 and DX51D quality of 0.5 mm thickness and pre-lacquering covering depending on needs (polyester, plastisol, PVDF, etc.).
Minimum roof pitch of 5% for covers without flap. Minimum 7% for covers with flap.
