Choosing uPVC flush sash windows
The flat frame line is the starting point.
Flush appearance
The sash closes level with the outside frame. Look at the whole elevation when choosing where openers and fixed panes sit.

White, coloured and timber-effect foils change the appearance of the frame. Compare them with handle finishes using actual samples.

Bars divide the glass visually. Their position should follow the proportions of your windows and any adjoining windows you are keeping.

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.

Product choices, pricing and what happens before we fit.
What is the difference between flush and standard casements?
A flush sash closes level with the outer frame on the outside. A standard casement sash projects from it. Both open on hinges; the choice changes the frame lines you see from the street.
How do I get a price for uPVC flush sash windows?
Build your price online using approximate sizes, or book a free consultation and we price the job with you. Both use the same software and price list. Once you decide to go ahead, a technical survey confirms the measurements and fitting details before anything is made.

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.
