Thermal-break aluminum windows, explained

The problem it solves

Aluminum conducts heat quickly. Without a break, an aluminum frame can feel cold in winter and transfer heat in summer, and condensation can form on the inner surface.

What a thermal break is

A low-conductivity polyamide strip is placed between the inner and outer aluminum profiles, interrupting the path heat would otherwise travel through the frame.

When it is worth the cost

Heated or cooled buildings, cold or hot climates, large glazed areas, and anywhere condensation on the frame would be a problem. It is less critical for unheated spaces.

What it does not solve

A thermal break improves the frame, not the whole opening. The glass build-up, installation detail and sealing matter just as much to the result.

How it is specified

Tell us the climate and whether the building is conditioned. We propose a standard or thermal-break profile and state which one the quotation covers.

Checking what you are buying

Ask which profile the quotation is based on. If price comparisons look surprisingly different, the frame system is often the reason.

A thermal break is a frame decision that pays back in comfort, but only as part of a complete opening specification.
