Products Sandwich panels

PUR-AL

Sandwich panel with a thermal insulation core made from rigid polyurethane (PUR) or polyisocyanurate (PIR) foam, covered on both sides by a galvanized steel sheet. There is the option of a panel with one side covered with a reinforced polyester sheet and the other with a galvanised steel sheet and a polyester paint finish, or both sides can be equipped with a polyester sheet reinforced with fibre glass.

The polyester sheet reinforced with fibre glass provides the final product with significant advantages: long durability, minimum maintenance and ease of washing, high protection and hygienic properties, high resistance to impacts, suitable for food products as it prevents the growth of mould, does not absorb odours, and does not rust.
