To keep out the wind and rain we use our patented high performance, multi-functional weather seals. The airtight seal this creates helps to maintain your comfort inside your home. The Flush Sash dual seal is exceptionally watertight, with the added benefit of concealing any hardware. Any water that has found its way inside is quickly evacuated due to the intelligently designed  integral drainage gutter.


With its core designed around Heritage Sculptured Sash, the insulating properties of Flush Sash are even more impressive. A double glazed window with a U-value of just 1.2 epitomises this market leading product.
