THERMAL HEART™ residential windows and doors achieve the highest energy efficiency in our range and is suitable where the avoidance of cold and condensation is a priority.

Based on the Designer Series of high performance residential joinery, THERMAL HEART™ products include an insulator or thermal break between the aluminium interior and exterior. The transmission of cold from the outside is dramatically reduced, especially when double glazed units are included. Double glazing is standard in this range.

With a commercial grade outer frame the Designer Series with THERMAL HEART™ is suitable for a wide range of residential and architectural applications. Doors are suitable to heights of 2.7 metres. Double glazing to a thicknesses of 24mm - 32mm is possible. 

Because of the two-part construction of the Designer Series with THERMAL HEART™ profiles, a limited range of joinery with different colours on the inside and outside can be supplied.
