Discreet fitting and cost-effective

Secondary glazing is an effective and efficient way to enhance your listed buildings 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 buildings, and properties in conservation areas need to be mindful of the external appearance of their properties. They have to follow regulations in order to maintain the authentic appearance of their buildings.

However, that fact should not affect the comfort of those living in these Heritage or listed buildings.

Made to last

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. Protect your property with our secondary glazing for listed buildings.

The Benefits of Secondary Glazing for Listed Buildings

Character Retention

Since a property that is in a conservation area, or listed Grade I or II, cannot change their glazing without permission, secondary glazing offers a discreet alternative for enhanced performance.

Bespoke Styles

Heritage buildings can have elaborately shaped windows that might need tailored fittings. Our aluminium secondary glazing for listed buildings can be shaped and fitted to any shape or size, allowing us to cater to a variety of needs and requirements.

Thermal Performance

Our secondary glazing for listed buildings can improve your windows’ thermal performance by up to 65%, which is 10% better than double glazing. Your home becomes better at retaining heat in winter, and air conditioned cooling in summer.

Acoustic Performance

Sounds from outside can be quite disturbing, especially at night when you’re trying to sleep or relax. Our secondary glazing for listed buildings can reduce noise by up to 80%, giving you the peace and quiet you need.

Heightened Security

Our secondary glazing for listed buildings fits inside the window, discreetly adding a layer of protection to your home, in addition to the security your windows are giving you. These fittings require no access from outside, making them ideal for higher floors.

Great Value

For an affordable price, your secondary glazing gives you unbeatable performance. You also get an improvement in the functioning of your listed building. This gives these installations an amazing value for money.

Choice of colours
