The Complete Guide to Choosing the Right Glazing for Listed and Heritage Buildings

Upgrading the glazing in a listed or heritage property involves more than simply replacing old windows with new ones. It requires consideration of strict planning regulations, preserving historical charm, and the desire for modern performance.

At BGD, we understand these challenges. With over a decade of experience, we offer tailored glazing solutions that enhance period properties, ensure regulatory compliance, and improve energy efficiency.

Challenges of Enhancing Glazing in Historic Buildings

Planning Constraints:

Most historic buildings have conservation rules restricting glazing changes. The changes must ensure that the original look meets modern performance standards.

Maintaining Architectural Character:

Narrow sightlines, traditional materials, and original design details must be preserved to respect the building’s history.

Balance between Energy Efficiency and Security:

Period windows lack the secure locking mechanisms and modern insulation of modern alternatives, which renders them less efficient and secure.
