Fire resistance the spur for 'step change'in doors

Stertil Stokvis has expanded its product range by introducing a new door featuring a very special foam core. The PIR foam, from construction industry specialist Kingspan, represents a step change in modern door manufacture, says Stertil.

The new door is constructed from steel sandwich panels with a polyisocyanurate (PIR) core.

The polymer structure of PIR is superior to the industry standard polyurethane (PUR), in that it is difficult to ignite and self-extinguishing, thereby providing enhanced fire resistance. PIR already has an excellent track record in real fire situations in many different types of buildings including schools, hospitals, warehouses and factories.

As well as the improved fire resistance, PIR panels also offer enhanced longterm characteristics, such as low heat conductivity, excellent mechanical parameters and low water absorption.

Stertil Stokvis offers attention to detail, with high quality materials and precise process control in manufacture adding up to an expectation of long service.

The new door panels are HFC, CFC and HCFC free, with the insulation core having been awarded a Low Global Warming Potential classification. The excellent thermal properties of the door will also help keep energy costs down.

"We're very pleased to be adding to our range of doors with this new model," explains Andrew Georgiou of Stertil Stokvis. "This is a value-added and futureproofed product offering many benefits, which I know will be very appealing to specifiers, developers and building owners. Users of the new door can look forward to top performance, exceptional reliability and unparalleled health and safety features."
