What sets our alu-clad timber windows apart
A durable exterior
Aluminium is resistant to adverse weather and protects the timber.
Dimensional stability
Provided by the timber construction on the room side.
60 months’ guarantee
On the coating of the aluminium profiles, for installation more than 30 km from the coastline.
Three profile depths
68, 78 and 92 mm - every profile is also available as alu-clad timber.
Alu-clad timber window profiles
The construction stays the same. What changes is the frame depth, and with it the space for the glazing unit.

68 mm

Made for the house, not for a catalogue
We make all windows and doors to individual order - in the dimensions and divisions that follow from the design of the building.
Detail and construction of alu-clad timber windows
Two frames, two jobs.

Timber inside
Shapes the interior and provides insulation.

Aluminium outside
Increases the strength of the window, improves thermal insulation and protects the timber from the weather.

Thicker glazing units
Two frames hold thicker glazing units, which improves thermal insulation and acoustic performance.
Three aluminium styles
The cladding determines how the window reads from the façade. Rotate the profile to see it from the room side, from the façade side and in section.

Cladding style
Gemini Classic
Gently profiled outer edge, with a step that shows in the light. Made in depths of 68, 78 and 92 mm.
We show all styles at the same profile depth, 92 mm.
Timber colour and aluminium colour
The interior and the façade are finished in two different materials, so their colours are chosen separately.
Façade · aluminium
Cladding colour
The cladding colour is chosen from the Aluron Color Collection 2 palettes. The five collections differ not only in colour but also in surface finish.
RAL MAT Smooth matt in RAL colours.
RAL FS The same colour families, with a fine texture.
METALLIC FS Metallic colours.
ANODIZED & EFFECT COLORS Champagne, bronze, graphite, white.
DECOR MAT Wood grain and stone surfaces.
The final choice is confirmed on a sample.

Interior · timber
Timber colour
The timber colour is chosen from the range of finishes, separately for each species. On the room side it can differ from the cladding on the façade.
White
Clear
Cypress
Iroko
Afrormosia
Acajou

We agree the cladding style, frame depth and timber species once we understand the architecture and technical requirements of the building.
