What is Secondary Glazing?

Secondary glazing is the process through which a discreet, internal window is fitted to an existing single or double glazed window to enhance performance.  It’s seen as a desirable alternative to double glazing – especially for heritage properties – as it allows you to maintain the external character of the structure whilst taking advantage of the benefits created by double glazing. When you take advantage of secondary double glazing, you enjoy all of the benefits that come with an extra layer of insulation over your windows. This cuts down on heat transfer, which means that your home stays warmer in the winter and cooler in the summer. But it also insulates against sound and enhances the security of your property.

Increase the value of your property with Secondary Double Glazing

Secondary glazing actually exceeds the value of traditional double glazing. In addition to providing outstanding thermal and noise insulation, this style of glazing is also extremely discrete – to the extent that a casual observer would be unlikely to notice its presence at all.

This level of subtlety allows historic homes to retain their character whilst taking advantage of more recent breakthroughs in glazing. We offer a wide variety of styles and finishes that you can install at your property, ensuring that the finish you choose blends perfectly with the existing design style and motif that are already in place.

If you have any question about secondary double glazing and whether or not it’s the right choice for your property, please don’t hesitate to contact the team at Granada.

For Homeowners

There are many reasons for homeowners to consider installing secondary double glazing from Granada – beginning with thermal insulation. Air-conditioned spaces allow in less heat during the summer, while less heat escapes during the winter. Needless to say, reducing heat transfer through the windows can have a significant effect on your monthly heating and cooling bills. And with the range of styles we have available, you’ll end up with an attractive, unobtrusive finish that is sympathetic to the surroundings and existing window styles.

Why Secondary Glazing?
Sound Insulation

Secondary glazing offers the most effective sound insulation – significantly outperforming double glazing. From noisy roads to noisy kids, our windows can reduce noise levels by up to 80%.

Thermal Insulation
Thermal Insulation

Substantially improves the thermal insulation of existing single-glazed windows – reduces heat loss through the window by around 65% – around 10% more than double glazing.

Increased Security
Increased Security

Secondary windows offer an affordable, discreet, highly effective solution to enhancing building security. No external access is required, ideal for multi-storey buildings.

Retain the character of your property

One of the most important benefits of secondary glazing is the fact that it can enhance the technical performance of a property without detracting from its charm or character. By taking advantage of our glazing products, you’ll also benefit from added security, reduced draughts and 60 per cent boost in thermal performance when compared to single-glazed windows. Noise reduction is enhanced by an even larger factor. And all of this comes without the need to remove your existing windows or even erect scaffolding.

Value for Money

Secondary glazing offers better value for money compared to regular double glazing as it is often cheaper but has more benefits. Get your free estimate today and see the difference for yourself.
