What are Flush Casement Windows?

Flush casement windows are for those who want a classic style of window, but thanks to Hart Windows, they have been updated for a more contemporary look and feel. These windows sit flush within the frame. Thanks to this specific design, you get windows that look smart, clean and elegant, as nothing will protrude from your Guildford home. Due to the design of our flush casement windows, they are very popular with people who live in more traditional properties, but they also suit more contemporary homes.

Flush casement wines, which are also sometimes called flush sash windows, can be designed to recreate the look of timber. Unlike traditional wood windows, where the wood can be affected by bad weather conditions, our windows have a uPVC frame which does not crack, rot, or fade in harsh climates. This means that your flush casement windows will have a long lifespan and perform well for ages, whether you choose the customisable authentic wood grain finishes or not.

uPVC Flush Casement Windows Designed For Your Guildford Home

One of the reasons customers come to us for their sash windows is because they can be designed to fit the architectural style of your home and to suit your own personal tastes. Our windows can also be designed to fit your budget. Guildford residents can pick their own colours, authentic finishes and unique hardware, such as handles and Georgian bars. Whatever design you choose, you’ll get a flush sash window with slim sight lines for your home.

Our flush casement windows have a larger glazed area, and this allows you to have better views of the outside world and allow more sun to flood into your home. This natural light warms your house, and also, because of their air-tight uPVC frames, cold air is kept out. Our uPVC frames are completely weatherproof, which means that your windows will last for a long time, and maintenance is almost negligible; all you need is to wipe them down with a damp cloth. 

Hart Windows’ Flush Casement Windows last a long time and repel bad weather. Because of their uPVC frames, heavy rain and wind doesn’t damage the frames, you can rest assured that they will not rot, warp, fade or crack. Due to their classic appearance, these windows will not age in performance or style. Once you have our flush casement windows installed in your Guildford home, they will be there for ages.
