If you are looking for a traditional timber casement or cottage window design, Norrsken’s P11T Outward Opening Timber Window is perfect. The all timber construction of the windows makes it suitable where conservation or planning requirements stipulate timber. 

This double glazed outward opening window delivers very good performance - above average for a double glazed window.

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

The double glazed unit is a 24 mm unit with argon gas filling, warm edge spacer bar and an internal pane of Low-E glass. Whole window U-Values are around 1.2 W/m²K. 

The frame is available in two depths 116 mm (+ 12.5 mm for aluminium cladding) and 92 mm. On the deeper section frame a decorative moulding finish is available.
