Choosing uPVC casement windows
Choose the opening before the finish.
Room-by-room openings
A fixed pane keeps the view open. A side or top opener provides ventilation. We check handle reach, outside clearance and the layout of adjoining panes.

Compare white and foiled finishes with the S2 Signature handle range. Swatches come to your consultation so you can see the finish against your own brickwork.

Choose clear glass for the view or obscured glass where you need privacy. We check ventilation and the glazing specification as part of your window order.

Dunstable homes, and what to check first.
The homes. Dunstable grew where Watling Street crosses the Icknield Way. There are older buildings around the Priory Church and the centre, but most homes are interwar and post-war, below Dunstable Downs.
What that means. Most Dunstable homes are straight replacements, where the decisions are glass, colour and whether to change the opening style. Older properties near the centre need more care.
Check first. Houses from the interwar years sometimes still have steel or timber windows. When they come out, the surrounding brickwork and lintels need checking before the new frames go in.

I had an excellent experience with Fenster Glazing from start to finish. Nick Perry and David managed the initial quote to installation process seamlessly, keeping communication clear, honest, and completely stress-free. When it came to the actual fitting, Zac and Shane did a fantastic job with the installation, working efficiently and leaving everything spotless. The professionalism from the entire team was top-notch, and the final result looks brilliant. I highly recommend them.
