What is Warmcore? Warmcore

Warmcore is a warm aluminium system created out of a desire to combine the desirability and durability of aluminium with exceptional thermal performance.

Warmcore® U-Value Performance

What is a u-value? U-values measure how effective a material is as an insulator. The lower the U-value is, the better the material is as a heat insulator. Current Part L Building Regulations require a U-Value of 1.8 W/m2k for replacement doors.
