120mm laminated spruce timber outward opening window with triple glazing.
next previous
Our highest performing outward opening product, this triple glazed window delivers truly outstanding performance and is s available in two versions - a certified passive house product and a standard non-certified version.

The certified version uses Spruce as the material for the timber frame and has an even higher glass specification. This combination offers ultimate performance.

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 50 mm unit with argon gas filling, warm edge spacer bar and two panes of Low-E glass. Whole window U-Values are around 0.68W/m²K.
