Frame and leaf insulation series 3000

All doors of the 3000 series are insulated. Both the frame and leaf are filled with a foil-faced polyisocyanurate foam sheathing of 50mm with insulation factor R14

Access door insulation - Series 1000 and 2000

Depending on the operating conditions, access doors series 1000
and 2000 can be sprayed with polyurethane underneath the leaf.
The Airmetic product meets ONGC 51-GP-23M standards. This polyurethane compound is a remarkably resilient and stable insulating material. Its thermal resistance by ASTM C-177 standards is 1.34 m²°C/W (72.6ft²hrºF/Btu-in) and is fireproof.
The insulation can be protected with a wire mesh or a full plate. This will protect the insulation from operational damages and will be more esthetic.
