Three lines, from entry level to passive-house standard. All three are thermally broken aluminium, made to measure, with a survey and installation. If you want metal outside and timber inside, timber-aluminium is a separate category, and we have that made too.
| Line | down to Uw | Installation depth | For whom |
|---|---|---|---|
| Basic aluminium | 1.05 W/m²K | 65 mm | Public buildings, blocks of flats and offices, where durability and a uniform appearance matter. |
| Premium aluminium | 0.97 W/m²K | 75 mm | A premium family house, where large windows and balcony doors are in the plan. |
| Exclusive aluminium | 0.56 W/m²K | 95 mm | A top-end family house or a passive house, where thermal insulation comes first. |
The figures are the manufacturer's official data, for the best version available. Click on the name for the detailed data.
The timber-aluminium window does not belong here: its structure is laminated timber and only its outer shell is aluminium. We describe it on a separate page.
Send us the sizes, or just how many openings there are. We come back within one working day and arrange a time for the survey.
