PUR Rigid Foam

Most warmly recommended: the inner core of polyurethane.

Advantages:

• Low weight, excellent heat insulation.
• Foam withstands extreme temperatures: short-term up to 250°C, long-term up to 110°C.
• Compressive strength is sufficient for supporting insulating glass in the opening.
• Produced under controlled conditions, the polyurethane quality is consistently high.
