Thermal break: what it is and when it matters
A thermal break separates the outer and inner parts of an aluminium frame with an insulating barrier. It reduces the transfer of cold and heat through the metal profile.
It is important because aluminium is strong and versatile but conductive. Thermal break allows aluminium windows to keep their design and structural advantages while improving energy performance.
Key technical criteria
It helps reduce heat loss, cold interior surfaces and condensation risk, but it must work together with suitable glass, airtight gaskets, an insulated shutter box and correct installation.
Common mistakes
When asking for a quote, check that the aluminium system includes thermal break and that the glass and installation details are specified. The profile alone does not define the final result.
What to ask for in the quote
Ask for the exact system, glass composition, opening type, installation details, guarantees and whether removal, shutter box and finishing works are included. This prevents comparing incomplete offers.
Practical conclusion
The best choice is the one that solves the specific problem of the home: heat, cold, noise, security, design or ease of use. A technical visit and a detailed quote make the decision more reliable.
