A new door from Stertil Stokvis is constructed from steel sandwich panels with a polyisocyanurate (PIR) core. The polymer structure of the PIR foam from Kingspan is difficult to ignite and self-extinguishing, thereby providing enhanced fire resistance. The PIR panels have low heat conductivity, good mechanical parameters and low water absorption.

Panels are HFC, CFC and HCFC free and the insulation core has been awarded a Low Global Warming Potential classification. The thermal properties of the door are said to help keep down energy costs.
