Designed to replicate the traditional timber sash window whilst incorporating the benefits of PVCu making this a virtually no maintenance solution. Our PVCu Sash Window operates like a traditional box sash window, both the top and bottom sashes slide up and down, and tilt inwards as standard

Heritage Solution

Modern windows no longer require Sash Horns, but they can be optionally specified to give the visual appearance of traditional timber box sash windows. We’re also able to offer a deep bottom rail option for replicating existing windows. A true heritage PVCu design is now available with the added benefit of improved visual aesthetic appeal

Easy clean facility

Our PVCu sliding sash windows come with an easy clean tilt facility as standard (excludes woodgrain external and smooth white internal windows), which allows both top and bottom sash to tilt inwards

Secured by Design

With our entire sash windows range, you have the opportunity to request SBD (Secured by Design). SBD focuses on crime prevention of homes and commercial premises and promotes the use of security standards for a wide range of applications and products, including windows and doors helping to put the resident at ease

Simply request at time of your quotation that the ‘Secured by Design’ window is required, as this is an optional upgrade

Energy Efficient

The glass specification is the most significant component when affecting the windows overall thermal efficiency. Each sliding sash window is supplied as standard with 24mm double glazed units incorporating Edgetech’s TruePlas spacer bar and manufactured in accordance with British Standards
