Introduction
The Townhouse Sash Window is a patented design – different to a sliding sash window – unique to the Irish market. The window is designed in the style of a sliding sash window but opens in a different way. From the outside the window looks just like a sliding sash window, but instead of sliding up and down it opens out and in. The top sash opens out and the bottom sash opens in. This gives full fire escape access, but also ensures that the window has a compression seal, making it 100% airtight. This is unique for sliding sash windows that are notorious for allowing air leakage.
