We recommend modern Timber/Alu-clad Alutrend windows 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 provides extra insulation. That is why the windows have a better heat-transfer coefficient as well as better soundproofness compared to regular timber windows.
Alutrend system offers extensive colouristic and aesthetic possibilities. 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.
As Alutrend Miratherm system has been designed particularly for passive housing, it is additionally fitted with a thermal spacer and special polyurethane insert which reduces the heat-transfer coefficient significantly.
Alutrend 78 Miratherm system is also available in the version with angular finish of the casement indoor moulding (Alutrend Qube 78 Miratherm).
