The PIR System is not only based on pre-insulated aluminium panels, but it also consists of accessories, tools and know-how necessary for the construction and installation in a masterly fashion. The Panel is a sandwich panel with external aluminum sheet covering a closed cell insulating material polyisocyanurate (PIR) foam which has a density of 50 kg/m³.
PIR pre-insulated panels achieve extremely high quality ducting as a direct result of the excellent insulation properties of PIR foam. The system also provides excellent internal air quality, a fine external finish, longlife material, and is lightweight, easily transported, manipulated, and constructed.
Ducting systems constructed with PIR pre-insulated panels can be installed either in the interior or on the exterior of a building, visible or with a false ceiling in residential and commercial use. As well, PIR pre-insulated panels are an excellent option in industry sectors such as food processing, electronics, pharmaceuticals, hospitals & medical centers, etc., where there is a need for a provision of a high level of quality and hygiene.
