Vertical sliding (VS) windows made from UPVC windows have authentic aesthetic appeal, providing all the low maintenance and high performance of 21st century UPVC window design. Our VS windows maintain elegant proportions of the traditional sash windows, whilst incorporating modern technology to deliver the low maintenance and high security of UPVC without the problems associated with timber sash windows.
Our sash windows are perfect for projects that want to retain the heritage style of old-style properties. A wide range of hardware features are optional and the standard configuration of our UPVC sash windows are energy efficient and will surely increase the value of your home.
“Our refurbishment project required maintaining the general style of the property to conform with the building regulations. When we contacted Ada, they provided with the details of the windows which we then passed onto the local authority for confirmation. This was very helpful and made the whole replacement process a lot smoother. We are thankful for Ada’s assistance in replacing our old timber windows with modern UPVC sash windows.” Mr Y……. – SOUTH WOODFORDt, E18
Thermal efficiency
Incorporating brush seals around the openings for effective weatherproofing and draught exclusion, our vertical sliding UPVC sash windows have a high energy rating as standard. They are a great choice over timber windows since they are double glazed to the high specification to enhance the thermal efficiency.
Optional hardware
Our VS windows have a wide range optional features that can be added to suite your requirements. From Georgian bars, to child-restrictors, and a choice of sill sizes to tilt features, we can cater for your requirements.
Safe and secure
Our vertical sliding UPVC windows are fully reinforced with aluminium and sliding sashes are reinforced with galvanised steel to resist deflection under extreme window-loading conditions. In addition, the windows are equipped with the latest locking devices to ensure properties are secure and maintain a high level of durability, safety and comfort.
