Double Glazing Existing Timber Windows

Upgrade your existing timber windows with double glazing to improve comfort, reduce noise and lower energy costs, all while preserving the original character of your home.

We offer a range of double glazing options, including high-performance Vacuum Insulated Glazing (VIG), delivering exceptional thermal and acoustic performance with a slim profile suited to heritage timber frames.

Original timber windows often feature single, thin glass panes that:

Original timber windows often feature single, thin glass panes that were never designed for modern performance standards. 

As a result, they can lose heat during winter and allow unwanted heat to enter during summer, making it harder to maintain a comfortable indoor temperature. 

These older panes also allow external noise to pass through more easily, while small gaps can let in draughts and dust. In addition, single glass panes are generally more fragile and provide less safety and security compared with modern glazing systems.

What does double glazing actually do?

Frequently Asked Questions

We get a lot of questions from homeowners who want better comfort, less noise, and improved performance from their existing windows—without replacing them. Below are some of the most common things we’re asked about our services and approach.

Yes. In many cases existing timber windows can be upgraded with double glazing without needing to replace the entire window. The glazing can be fitted into the existing frames while maintaining the original appearance of the windows.

Double glazing improves thermal insulation, helping keep your home warmer in winter and cooler in summer. It also reduces outside noise, improves energy efficiency and strengthens the glass compared to traditional single panes.

No. When installed correctly, double glazing can be integrated into timber windows while preserving their original appearance. This makes it a popular upgrade for character homes where maintaining the traditional look is important.

Yes. Double glazing significantly reduces the amount of external sound entering the home. The two panes of glass help limit sound transmission, which can noticeably reduce traffic, street and environmental noise.

Yes. By reducing heat transfer through the glass, double glazing helps maintain a more stable indoor temperature. This can reduce the need for heating and cooling, which may lead to lower energy costs over time.

Yes. Double glazing improves the thermal performance of the glass, which helps keep the interior glass surface warmer. This reduces the likelihood of condensation forming during colder conditions.

We offer a range of double glazing solutions suited to timber windows, including high-performance Vacuum Insulated Glazing (VIG). These systems provide excellent thermal and acoustic performance while maintaining a slim profile suitable for heritage frames.
