Timber Windows: Handcrafted Solutions for Your Home

One of the most important aspects when producing timber windows, including our handcrafted windows, is choosing the correct way of sealing or finishing the wood to ensure preservation and prolong the lifetime of the window.  


At TWJ Sash, we use a microporous paint created by Teknos UK, which offers a substantial range of colours to match any of the major paint supplier's colour charts. They also provide a wide range of translucent finishes and wood stains if you are looking for a more natural timber finish.  


We apply these finishes using a spray system in our in-house finishing department, which creates a smooth result and a longer lasting, low maintenance finish. When used alongside Accoya timber, we offer a 10-year guarantee against the need for repainting your casement windows.
