If you are looking for a traditional timber casement or cottage window design coupled with really high performance, Norrsken’s P31T Outward Opening Timber Window is perfect. 

The all timber construction of the windows makes it suitable where conservation or planning requirements stipulate timber. Its performance makes it suitable for energy efficient homes including passive houses.

The application of technically advanced sprayed coatings (in a full range of RAL colours) gives enhanced durability and a superb finish.

The triple glazed unit is a 48 mm unit with argon gas filling, warm edge spacer bar  and two panes of Low-E glass. Whole window U-Values are around 0.75 W/m²K. 

The frame is available in depths from 92 mm to 120 mm. On the deeper section frame a decorative moulding finish is available.
