What are thermally broken extruded aluminium profiles?

Aluminium is cost-effective, lightweight and easy to work. However, it’s also very good at conducting heat, which isn’t ideal when it’s used for things like doors and windows. It offers poor insulation in winter and little protection from heat in summer (admittedly not a huge problem here in the UK).

Thermally broken extruded aluminium profiles solve this problem. A thermally broken profile is effectively an aluminium sandwich, and contains non-conductive material that acts as a thermal ‘break’ or barrier. These thermally broken profiles can conduct up to 1,000 times less heat than aluminium alone.
