Leaded Windows

Windows, redefined.

Leaded & Decorative Glazing

Leaded glass has a rich heritage and has been a trusted glass feature of choice over many centuries. Originally leaded windows were made of small sections of glass supported in lead cames. With modern technology and improved energy efficiency this effect is achieved by applying the lead to the surface of the glass. This decorative style is still as relevant and popular as ever, enhancing both period and contemporary properties.

Leaded Window Styles

Our Stormproof and Flush casement windows compliment leaded glazing perfectly, with their slim sightlines and equal glass dimensions. We can manufacture your windows with elegant and attractive leaded glass, whether you require square leaded, diamond leaded, Queen Anne or a custom design of your choice. We can even incorporate leads with coloured/stained glass, creating a completely unique window for your home.

Each and every leaded window we create is completely bespoke, so if your property has existing, decorative windows that you would like to replicate, our Evolution Approved Retailers can help you design them like for like to maintain the original look of your home.

Storm Leaded Windows

Our Storm leaded window has taken inspiration from timber, giving it a robust, yet beautiful styling as well as intricate detailing to joints and finishing touches. The ground breaking design means that they carry exquisite styling and features that are usually found on a traditional timber window, whilst offering a host of additional benefits, and none of the drawbacks.

Storm leaded windows are not only aesthetically pleasing, but they also offer exceptional energy performance against the British weather. Our Storm window provides a remarkable thermal performance and delivers an impressive A+ 13 energy rating as standard. Storm leaded windows can also be upgraded to an even higher level of energy efficiency with triple glazing, or to incorporate our innovative noise reducing acoustic glass.

Flush Leaded Windows

Flush leaded windows showcase sleek window lines that fit flush in to the window frame, unlike Storm windows that overlap the frame. This gives the Flush leaded window a simple and elegant aesthetic.

These stylish, virtually maintenance–free leaded windows have been developed based on authentic, traditional design and are very popular in period homes and cottages. There is also increasing demand for their use in contemporary new homes and minimalist conversion properties due to their clean, sharp lines.

As with our Storm windows, our Flush leaded windows can also be upgraded to incorporate acoustic glass, or improved energy efficiency with triple glazing. If you want low maintenance modern features with a timber-look feel, then our modern alternative is the ideal choice.
