The Energi Altitude Window Series

Designed for impressive performance,

The Energi Altitude Window Series meets the
CW Classification, meaning mid-rise buildings with
institutional application. It provides the possibility of
multiple assembly and opening configurations
(casement, awning, fix, tilt).

This high energy efficient window features extruded
aluminum profiles interior and exterior connected to
the thermal insulation system "Performance Core",
representing the core of the window.

The aluminum profiles for the frame are mechanically fastened with steel screws inserted in the appropriate aluminum profile grooves. The aluminum profiles for the sashes are assembled with aluminum corners completely adjustable for a perfect exterior finish.



The frame depth is 117mm (4 5/8") or 152mm (6"). The standard sash depth is 73mm (2 7/8") with a height of 44mm (1 3/4'') and designed for 25mm (1") glazed units. Mullions are 116mm (4 9/16") deep.



Continuous flexible weatherstrip and glazing beads, including the corners, on the glazed unit perimeter, ensure optimal insulation. A structural sealant joint is inserted on the window periphery on the interior part of the operating sash.


Performance Core

The thermal insulation system "Performance Core" is fusion assembled ensuring a maximum air and water tightness.
