Breathe new life into your property with new or renovated timber sash windows
Made from two glazed panels that slide open and shut independently of one another, the wooden sliding sash windows of today have come a long way over the last 350 years or so. Manufactured in-house using time-honoured joinery skills fused with future-proof technology, with over 40 years’ worth of experience designing completely new wooden sash windows that seamlessly replicate the originals, retaining your building's authentic period styling is made easy with Ventrolla. Or, if your original timber sash windows are draughty, rattling, or inefficient, we can also provide industry-leading wooden sash window renovations with our unique patented perimeter sealing system.
