Further Details:

The Scandinavian-designed S Series window is our innovative sliding sash window with a tilt function on the lower sash. This custom made window combines Scandinavian design and quality with beautiful, timeless and traditional British looks.

Traditionally, sliding sash windows often have characteristically low energy efficiency, which deteriorates with age. S series, however, changes this. Featuring ground-breaking hardware, the S Series has some of the best water and air-tightness on the market – just as effective as a casement window. By using super low argon gas as standard, our sliding sash window has a U value of 1.2 W/m^2k and 39 dB sound reduction – meeting low energy requirements for 2020.

Upon opening the window, the sashes are sheared – thus avoiding wear on the weather strip. On closing, the sash presses against the weather strip, creating a tight seal. Furthermore, the window is designed to be hassle-free to operate: the bottom sash can be tilted inwards, facilitating handling considerably and therefore allowing for easy and safe window cleaning. In addition, night time trickle vents (20-23mm) and a lockable handle on the lower frame are configuration options.

The high density of the slow-grown Nordic pine provides the S series with a high durability class. The application of microporous paints further improves the durability. The paint allows the timber substrate to breathe freely and minimises the chance of paint bubbling over time.

The window can be combined with mullions, transoms, skylights and fixed sections. In other words, the customer has every option to find the combination best suited for the exact need.
