Sleek and unobtrusive design

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


Increased thermal and acoustic performance

If you’re unable to change your existing windows, installing secondary glazing in listed buildings is the most effective method to keep external noise out and keep the heat in. Our ultra-high-performance frames are able to reduce external noise levels by up to 80% and reduce heat loss by up to 65%. All this whilst retaining your properties authentic aesthetics.

An effective alternative

If you own a listed property or live within a conservation area, you may be unable to alter or replace your existing windows. This isn’t the case for secondary glazing, which can accompany your primary window and greatly aid thermal and acoustic performance. With a simple, mess-free installation process, secondary glazing is incredibly popular within listed buildings.


Manufactured to perfection

Engineered using industry-leading technology, all of our listed building secondary glazing units are produced in-house at our 40,000 square foot manufacturing. Our entire product range is rigorously tested throughout every stage of the production process to ensure a quality finish, time after time.
