Flush Sash Windows

Whether your home has heritage styling or is much more modern, flush sash windows installed by Cleveland Conservatories are a great choice. Combining the beauty and elegance of traditional timber with the energy-saving and security benefits of PVC-U, flush sash windows make a stunning addition to any property. With an unrivalled aesthetic appeal, they’re perfect for updating period homes, country cottages and modern townhouses. In fact, we’d even go as far as saying that they’re one of the most attractive window options available on today’s market. What’s great about this style of window is the attention to detail you don’t always get with other options. Boasting traditional looks yet made with the latest technology, flush sash windows have a symmetrical design that helps to give your property balance and harmony. We have been fitting brand new windows in Middlesbrough, Teesside and surrounding areas since 2000, building a reputation you can rely on.

Features Of Flush Sash Windows

The Genesis flush sash window is a traditionally styled flush casement window that’s available in two options; choose the mechanically jointed system that ensures the windows look like traditional timber or the Graf welded option to create the look of engineered timber. These result in a seamless appearance that brings a new lease of life to your property. These windows are available in white and 26 colourways as standard. With plenty of unique woodgrain foil colourways on offer, you can complete the look of your new windows with matching ancillaries, trims and accessories. With superb insulating properties, the Genesis flush sash easily achieves a thermal window energy rating of ‘A’. They also come complete with high-security locks and hardware, helping to achieve the enhanced security accreditation PAS 24.
