Timber/Alu Windows

To suit your needs we also offer Timber/Alu windows in the following product lines:

We recommend modern Timber/Alu windows Alutrend for those customers who appreciate natural wood and also want the maximum window longevity at the minimum maintenance cost. Their construction involves beautiful wood inside and durable as well as easy to maintain aluminium. The total window frame depth is as much as 90 mm. An air space between the timber and aluminium frames is an extra insulant. That is why the windows have a better heat-transfer coefficient (1.1-:-1.2 W/m2K) as well as better soundproofness compared to regular timber windows.

The window indoor side can be made of pine, meranti or oak wood and coated with translucent varnish (with visible wood structure) or with a body colour chosen from RAL pallet. Alu-clads (on the outdoor side) may be coated using a special technique to imitate any wood species or coated with a body colour chosen from RAL pallet.
