Low maintenance and long life in 68mm
Inside view of Villa Modena with sliding doors Alu 90

Alu 90 window is the result of the research to increase the duration of windows in time, by combining 68 mm wood with external aluminium cladding, thus eliminating the need for maintenance and varnish refreshments externally.
The aluminum is provided in different finishes and profiles which cover a wide range of colors and shapes suitable for any type of needs.

Unlimited customizations

This window can be further customized by combining different types of internal glazing beads with different external cladding, creating a large variety of compositions that will satisfy even the most demanding tastes.
This system can be manufactured in its standard version with trims and visible hinges, or in a special version with flush internal/external wall installation and concealed hinges.

thermal characteristics

Uf calculation based on a single sash window 1100×1450.

Thermal transmittance of the frame:
Uf = 1.33 W/m2K for light wood (i.e. fir) – UNI EN 10077-2

Thermal transmittance of the frame:
Uf = 1.63 W/m2K for heavy wood (i.e. oak) – UNI EN 10077-2

Thermal transmittance of the window to:
UW = 1,2 W/m2K *

*THE UW THERMAL TRANSMITTANCE OF THE WINDOW MUST BE CALCULATED EACH TIME BASED ON THE SIZE, THE TYPE AND THE GLASS USED.
