Classic Timber Looks With Modern UPVC Performance
Beautiful flush windows manufactured by Emplas and precision-fitted by our Martlesham team. Choose the standard Profile 22 system or our fully mechanical heritage timber-look — both British-made, thermally efficient, and covered by our 10-year guarantee.
The Elegance of Tradition, Reimagined
Flush casement windows have transformed the way we look at UPVC. Instead of the overlapping 'lip' found on standard modern windows, the sash on a flush casement sits perfectly level within the frame when closed. This clean, flat aesthetic beautifully mimics traditional 19th-century timber joinery, making it one of the most popular window styles we install from our Martlesham base for properties across Kesgrave, Ipswich, Woodbridge, Felixstowe and all of Suffolk and Essex.
We partner with leading manufacturer Emplas to supply two distinct tiers of flush window. The first uses the highly acclaimed Profile 22 Optima system, combining standard UPVC welded joints with a sleek flush exterior. For those looking for the ultimate authentic touch, we offer a fully mechanical heritage timber-look option, featuring traditional 90-degree joints, deep bottom rails, and period hardware.
Whichever system you choose, your installation begins with a free, no-pressure survey, is protected by our 10-year guarantee, and is fully FENSA-certified for complete peace of mind.
Choose Your System
Not sure which is right for your home? The standard Profile 22 provides sleek, flat lines and exceptional value. Our fully mechanical timber-look system boasts authentic 90-degree joints, making it almost indistinguishable from real wood. We'll show you samples of both at your free survey.
Profile 22 UPVC Flush Casement
A beautifully engineered flush window manufactured by Emplas. It features modern diagonal welded corners but delivers the coveted flat exterior finish. With its 70mm frame and multi-chambered profile, it's a fantastic, cost-effective way to modernise a 1930s semi in Ipswich or bring character to a newer build in Kesgrave.

Frequently Asked Questions
What Our Window Customers Say
Reviews related to our flush casement windows
We wanted to replace the old wooden windows in our cottage and the fully mechanical timber-look ones Dave recommended are perfect. You honestly can't tell they are UPVC until you touch them.
Homestyle fitted flush casement windows throughout our whole house in Agate Grey. Superb service and the lead times were exactly as promised. The house looks so much more modern.
Absolutely brilliant from start to finish. No pressure, great advice on the hardware options, and the installers left our home absolutely spotless.
Cannot recommend Homestyle enough. The fitters were polite, tidy, and their attention to detail on the finishing trims around our new flush windows is exceptional.
