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.Get a free quote
