Preserving character and charm

Our bespoke secondary glazing range is an ideal solution for listed properties and homes within conservation areas. Where replacement windows are not a viable option, secondary glazing provides all the thermal and acoustic benefits you’d expect from a 21st century window system, without damaging the unique aesthetics of the primary window.

Sleek, unobtrusive design

Improving the thermal and acoustic performance of your property shouldn’t negatively impact the character of your home. Our entire range of bespoke secondary glazing products come equipped with durable, slimline aluminium frames that accentuate the stylings of the existing window.

Increased performance

Installing secondary glazing is an effective method of keeping external noise out and keeping the heat in. Our ultra-high-performance frames can reduce external noise levels by up to 80% and reduce heat loss by up to 65%. All this whilst retaining your properties authentic aesthetics.

Purpose-built to suit all property and window types, our secondary glazing product range comes in a variety of styles.
Horizontal Slider

Suitable for a range of windows – including both casement and fixed – our horizontal sliding units open from side to side and are slim, versatile and easily accessed for both cleaning and ventilation.
Best paired with: Any window with vertical bars.

Lift Out Unit

Similar to our fixed units in concept and design, but with the ability to easily remove the frames to allow for increased airflow and improved access for cleaning.

Hinged Unit

With no transoms or mullions to spoil the view, our hinged secondary glazing windows are a truly unobtrusive secondary glazing option. The unit opens like a door and is available with a multi-point locking system or butt hinges.

Fixed Unit

Our fixed units are an independent window that is permanently fitted on the inside of the existing door or window.
Best paired with: Rooms where space is limited.
