Flush Casement uPVC Windows

Profile 22 Optima Flush Casement uPVC windows can be paired with contemporary grey finishes or a wealth of period detailing to offer complete flexibility for modern architectural installations or period homes.

Profile 22 Flush Casement Windows

Designed and manufactured in the UK, the Optima Flush casement window from Profile 22  offers leading-edge levels of performance with U-values as low as 1.2W/m2K with Window Energy Ratings of up to A+.

Finished in contemporary greys, it delivers a very clean architectural aesthetic, making it ideally suited to modern installations.

The Profile 22 Flush Casement Window is also available in a wide range of heritage colours and finishes plus period detailing, making it ideal for heritage installations, offering a low maintenance match to traditional timber windows.

With a simple chamfered finish to the sash externally, the outer frame is available in either the Optima sculptured (QS) or chamfered (QC) finish internally. The 24mm internal bead comes in a Sculptured (Ovolo) shape for perfect internal finish.
