Inward Opening Sliding Sash

Norrsken’s fantastic sliding sash window design is perfect for traditional homes and ensures excellent weather performance even on stormy days. Upon opening the window the sashes are separated, thus avoiding wear on the weather strip. On closing the window the sashes are pressed against the weather strip, making the window shut very tight.

Our sash windows are fitted with Torso balance springs and a handle on the bottom sash. If the window is being fitted with an opening top sash the handle is fitted on the top rail. The bottom sash tilts too for easy cleaning and convenient ventilation.

This made-to-measure, vertical sliding sash window is only available as double glazed timber in any RAL colour or stain.

The construction of a timber sash window is designed to have excellent thermal performance and functionality during different seasons throughout the year: in high humidity, in dry conditions, when it’s cold or hot.

Gaskets and insulated glazing units used in the design ensure air tightness and energy efficiency. Built with top grade laminated, responsibly sourced, slow grown timber and the use of tried and tested hardware help to prolong your window's life span, lasting a lifetime or more.
