Thermal break window & door profiles
Thermal break profiles join an inner and an outer aluminium section with a glass-fibre reinforced polyamide strip, so heat cannot flow straight through the metal. They are the standard for energy-efficient windows in cold and mixed climates, and are supplied as full systems with frame, sash, mullion and bead profiles.

Questions
Can the inside and outside be different colours?
Yes. Because the inner and outer aluminium are separated by the polyamide strip, each side can be coated in its own colour before assembly.
Do you supply profiles only or complete windows?
Both. We supply the extruded profile system to fabricators, or finished windows and doors assembled and glazed in our factory.
