Why Choose Secondary Glazing?

Cost-Effective Option

Secondary glazing is often much cheaper than fully replacing your single-glazing and still improves thermal efficiency.

Enhanced Energy Efficiency

Secondary glazing can help keep your home warmer in the winter and lower your energy bills.

Acoustic Insulation

Our secondary glazing helps keep external noise out by improving acoustic insulation.

Ideal For Listed Homes

Our secondary glazing is ideal for period properties, which may have restrictions on replacing windows.

Save Existing Frames

Secondary glazing allows you to keep frames that are already in great condition and maintain the original aesthetics.

Quick Installation

Because it doesn't involve replacing the entire window, secondary glazing is often much quicker to install than new windows.

Secondary Glazing In The South West

We expertly install secondary glazing in properties across the South West, including Devon and Cornwall. Our team of experts will work with you to find the best solution for your home, and we take care to make sure that every project is completed with precision and professionalism.

We understand that renovation works can cause disruption, which is why we take every possible step to ensure a seamless and stress-free experience. Because secondary glazing doesn't involve replacing the entire window, we can also install it much quicker than if we were to install new windows.

Perfect For Listed Buildings

Older homes typically contain single-glazed windows, which aren't as thermally efficient and can lead to heat loss and higher energy bills. Listed buildings and properties in conservation areas can sometimes have restrictions which can make replacing single-glazed windows difficult or expensive.

Secondary glazing helps you improve the thermal efficiency of your windows without having to replace the frames, so its often a much better option in listed homes. Our secondary glazing is designed to help you improve the energy efficiency of your single-glazing while still maintaining the original aesthetic of the window, so you don't have to compromise on style.

What is secondary glazing?

Secondary glazing is a method of adding an additional layer of glazing to the interior side of an existing window to improve insulation, soundproofing, and security. It is ideal for homes with single-glazed windows when replacing the windows is not an option.

Can secondary glazing be installed on any type of window?

Secondary glazing is a versatile solution and can be installed on most types of windows, including sash windows and casement windows.

It's difficult to give an accurate estimate as every project is different. If you'd like to find out how much secondary glazing would cost in your home, please get in touch for a free, no-obligation quote. You can call us on 01752 938120 or email sales@dnawindowsolutions.co.uk.

Will secondary glazing help improve energy efficiency?

Yes, secondary glazing can enhance the energy efficiency of your home. It creates an additional insulating barrier, reducing heat loss in the winter and preventing heat gain in the summer. This can lead to lower energy bills.

Does secondary glazing affect the aesthetics of the original window?

Secondary glazing is designed to be unobtrusive and can be customised to match the existing window frame. In many cases, it is barely noticeable from the outside, preserving the original aesthetics. This makes it an ideal option for historic or listed properties.
