Wooden / Aluminium Windows and Door

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.

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 1100x1450.

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.

FRAME SPECIFICATIONS

Air permeability: EN 1026 – UNI EN 12207 Class 4

Water tightness: EN 1027 – UNI EN 12208 Class 9A

Wind resistance: EN 12211 – UNI EN 12210 Class C5

Noise reduction up to: RW = - 43 dB

VARNISHING

Performed in three phases before the hardware is assembled:
