THE sash and case window design has endured around the globe thanks to classic looks and longevity. In years gone by they were manufactured from timber which, with regular care and attention, ensured a healthy lifespan. But this can be expensive and time-consuming, and doesn’t always guarantee the look and weatherproofing achieved by upvc windows.  

Now the classic sash and case design can be replicated in upvc, with enhanced insulating properties and no need for constant tender loving care.
