PIR-GR

A rigid polyisocyanurate (PIR) foam panel coated on both sides with lacquered embossed aluminium. One of the sides of the panel is covered with an aluminium sheet coated with a white protective lacquer. The material's main characteristics are: a high thermal resistance which enables the use of thinner insulating panels, and rigidity and lightness which facilitate handling and installation. The high insulating properties of the PIR GR panel ensure a high thermal comfort once installed. The aluminium finish protects the panel from aggressive environments, facilitating pressure washing for an optimal hygiene of agricultural installations.

On account of its rigidity, the PIR GR panel can be manufactured in lengths of up to 4.5 metres. It is easy and quick to install with its simple assembling system using PVC profiles and the panel's optional groove system. The aluminium finish, acting as an excellent barrier against vapour, and the joint cover system, are key factors to ensure its longevity when installed.
