SW17 window is a modern Nordic design for zero energy homes: outward opening window, with lim profiles ensures excellent energy effiecency and broad view. With 3-glazing and two sash gaskets U-value Uw = 0,75 W/²K is achieved.
SW17 window is available as timber window and also as acluclad window. Design comes with variable frame depth to meet better different wall constructions and installation situations. If more traditional internal desing is a criteria, one can choose so called country style profiles.
Note: U-value (0.60 – 1.2) indicates thermal transmittance of window. Smaller value equals better thermal insulation.
