Thermally Broken Aluminium Windows

Window, door and shopfront systems

Thermally Broken Aluminium Windows

High-performance windows for homes and commercial buildings with our polyamide thermal break W65 TB and W80 HI series.

Priced per project

Aluminium is strong and durable, but it conducts heat very well. Thermally broken systems cut this bridge by inserting glass-fibre reinforced polyamide strips between the inner and outer profiles. The width of the break and the insulating foam inside the profile determine the Uf value.

Our series

  • W65 TB: 24 mm polyamide break, Uf 2.1 W/m²K; the standard series for homes and offices.
  • W80 HI: 34 mm break with foam fill, Uf 1.4 W/m²K; for projects targeting high energy performance.
  • D70 TB: A reinforced door series for heavy-traffic entrances such as schools, hospitals and shopping centres.

Finish and colour

Profiles are finished with Qualicoat-certified powder coating (all RAL colours, matt and textured options) or Qualanod-certified anodising. Different colours can be applied inside and out.

Residential projects

For housing and residential projects we produce standardised window sets for each flat type and plan installation by block and floor. Windows and balcony doors are CE-marked to TS EN 14351-1.

Frequently asked questions

How do you choose between a stick and a unitised facade?
Building height, programme and site conditions decide. For buildings under 10 storeys with a flexible programme, a stick facade is economical. For 15 storeys or more, fast-track projects or city sites where scaffolding is impractical, a unitised facade offers an overall cost advantage.
Does thermally broken aluminium insulate as well as PVC?
The W80 HI series, with a wide polyamide break and foam fill, reaches Uf 1.4 W/m²K, close to a good PVC series. Aluminium's advantage is that it delivers this with much slimmer profiles and far larger sash sizes.
What do you need to prepare a quote?
Architectural floor plans, elevations and system sections (DWG or PDF), plus any specification and bill of quantities, are enough. You can upload your files through the project quote form, and we send a system proposal and budget range within five working days.
Why does pricing vary from project to project?
Glass type and size, profile sections driven by wind load, colour and finish, anchor conditions, building height and access method all affect cost directly. As aluminium and glass prices follow exchange rates, quotes are valid for 30 days.
Is a mock-up test needed on every project?
No. Test reports exist for our standard systems. But on tall buildings, bespoke details or where the specification requires it, we recommend a full-scale mock-up test. Its cost and duration are shown separately in the quote.
