Does your listed property need a lot of energy to stay warm? Is outside noise disturbing you? Let our secondary glazing come to your rescue.
Secondary glazing is an effective and efficient way to enhance your listed property’s thermal performance and reduce noise. This cost-effective and discreet fitting will give you all the functionality without affecting the appearance of your property.
Owners of Heritage buildings, listed properties, and properties in conservation areas need to be mindful of the external appearance of their buildings. They have to follow regulations in order to maintain the authentic appearance of their properties.
However, that fact should not affect the comfort of those living in those buildings.
The warmth of the home is imperative for the comfort of its residents. In order to keep rooms warm, you need to be able to trap the heat in.
Single glazing can allow heat to dissipate rapidly, and even double glazing is not as effective as secondary glazing at improving the heat efficiency.
The best part is, our secondary glazing fits in so discreetly that you can continue with your heritage windows and still improve the performance of your home. What’s more, you even get acoustic insulation at the same time.
Our high-durability aluminium secondary glazing comes in over 200 RAL colours. The fittings are extremely long-lasting, with a 5 year warranty on the fittings and a 2 year warranty on the movable parts.
