A unique outward-swinging window style suited to multiple applications

One of the industry’s newest and most original window styles, aluminium overswing windows from Evaframe allows you to offer customers a greater control over their windows’ opening functionality. The 21st century equivalent of an upwards sliding sash, this latest design lets the sash swing over at a 45 degree angle, and can be configured to be able to do so either from the top or bottom of the profile.

We exclusively supply all our overswing windows using the SPW600E aluminium system to guarantee peak functionality while never compromising the unrivalled energy efficiency and heat retention levels modern homeowners have come to expect. Each overswing window is supplied thermally broken to offer tradesmen low u-values and greater versatility. They’re also available in single or dual colour finishes in any one of 150 distinct colour, making it easy to cater for a multitude of applications.

In our experience, overswing windows have enjoyed immense success when used for commercial projects and high-rise properties due to their ability to ventilate without revealing a large open space. Especially when taking into account the narrow sightlines each unit offers, in buildings where it doesn’t make sense to fully open up a property’s aperture look no further than an overswing window from Evaframe.
