Our outward opening Triple Glazed Wood & Aluclad SW11 Window is the answer to today’s need for higher energy  efficiency  combined with the simplicity of Nordic design – slim frame profiles coupled with triple glazing increase the available glass size maximising light gain and minimising heat loss.

This window is available in fully reversible, side hung, side hung projecting, top hung projecting, fixed light & shaped frame styles.

The triple glazed unit of our SW11 window comprises two Low E panes and one standard pane of glass with Argon gas filled cavities and is 40 mm thick overall. To achieve the lowest possible U values we recommend the use of SGG Swisspacer spacer bars which provides the best warm edge solution. This window has a U Value of 0,97 W/²K.

With a flat internal design, sliding hinges hidden between the frame and sash and energy efficient triple glazing the SW11 window is a perfect solution for modern houses.
