A-rated sliding sash windows tailored to homes in Cornwall
Thanks to advancements in construction material production, vintage vertical sliders are making a real comeback within discerning Cornish residences. Full of character, incredibly weather-resistant, and splendidly airy and light, sliding sash windows are typically installed singly or in illuminating bay arrangements. Recognised by one or two moving panels, modern sliding sash windows (like ours!) often feature a variety of multi-pane effects to recreate the classic appearance of smaller panes of glass, whilst benefiting from a range of high-performance, low maintenance features that were simply not possible with original timber sliders.
Dedicated to maintaining and restoring our local heritage with compliant, affordable, and enduring window installations, this is why we manufacture and install quality uPVC sliding sash from the superb Inspiration range by Synseal.

From replacing original timber sliders to adding a classic twist to modern developments, we're confident our multi-chambered uPVC frames will transform your home in every aspect imaginable. With sliding sash window installations from RJM Windows you can look forward to:
