Get Made-To-Measure Secondary Glazing From Bellwood’s

Bellwood’s offers a variety of different styles, frames and types of secondary glazing to suit any property. This includes fixed units, which fit to the inside of the window frame and give the appearance of traditional double glazing. We also offer horizontal glazing, which is incredibly popular as it fits over large windows and gives all the benefits without compromising on style.

For period properties with sash windows that can’t be replaced, we have vertical glazing solutions to help you retain your period features while also improving energy efficiency and adding an insulating layer against outside noise. There are also hinged units, which are suitable for all existing window styles and open like a door to add additional protection against heat loss and external noise. If you need secondary glazing that can be removed for easy cleaning, we have lift-out units that are easy to replace.

When it comes to secondary glazing, one size doesn’t fit all. Thankfully, Bellwood’s is able to draw on our decades of industry expertise to create bespoke secondary glazing solutions for uniquely shaped properties or homes with large windows that need custom styles. These solutions can be arched or fitted to any shape or style to get the look and feel you’ve always wanted.

Aside from our range of different styles, we have two main types of secondary glazing systems. The Classic secondary glazing range is able to accommodate 4mm glazing. Classic panels come fully equipped with slimline, durable window frames that combine style with exceptional performance. Our Enhanced secondary glazing panels come with all the noise insulation and style benefits of the Classic range, with the added bonus that they can accommodate up to 10.8mm glass.

The Benefits Of Secondary Glazing

Secondary glazing is the perfect solution for a wide range of properties and styles, as it’s entirely customisable. Because secondary glazing panels attach to existing windows, they can be ideal for listed buildings and properties where existing windows can’t be replaced, but we work on properties of all styles and types throughout the North East. Many homeowners love secondary glazing because it seamlessly integrates with their existing windows or doors. Some of the other key benefits of secondary glazing are:

Noise Reduction

Noise pollution can be a major issue for many homeowners, particularly if you’re living in a busy city like Durham, Newcastle or Gateshead.

Many homeowners throughout County Durham need additional sound insulation to protect them from noises, such as traffic on busy roads or local commercial buildings.

Our secondary glazing is made using state-of-the-art machinery to create a tightly sealed frame which reduces noise levels by up to 80%, meaning you can create a calm, peaceful atmosphere that’s perfect for rest and relaxation after a busy day.

Additional Insulation

With energy bills constantly rising, many homeowners are looking for ways to cut back on heating costs.

With secondary glazing, you can add an extra layer of insulation without having to replace the entire window.

This is ideal for older homes in conservation areas, heritage properties, or listed buildings, as it means that you can keep your period features and original windows while also making a noticeable difference in the temperature of your home and making it more thermally efficient.

Improved Security

Windows and large glass doors can be a particular security concern for homeowners, but with secondary glazing, you can add extra protection from intruders.

Unlike traditional windows, secondary glazing units are difficult to open from the outside, protecting you and your family from forced entry by criminals.

All of our secondary glazing window frames are made from only the most durable, high-quality aluminium and are securely fixed by our expert fitters to resist external force and improve your safety.

Can I Fit Secondary Glazing Myself?

The experts at Bellwood’s Windows And Doors fit secondary glazing for our clients to ensure that the solution gives them all the benefits they expect. While we don’t offer DIY secondary glazing solutions, our lift-out panels can be removed for easy access for window cleaning or maintenance.

Does Secondary Glazing Reduce Condensation?

Secondary glazing can help with condensation reduction by limiting the cold air that can enter your property. However, it won’t fully remove the issue, especially if your original windows have a large air gap that’s causing a draught. To reduce condensation problems, you might want to discuss replacing your existing units with double glazing.

How Much Does Secondary Glazing Cost?

Secondary glazing is a cost-effective solution that can be a great alternative to replacing your entire window or door unit. The exact cost of your secondary glazing project depends on a variety of factors, including the type of system you choose, the thickness of the glass, and how many secondary glazing units you need to add to your property. Bellwood’s offers great value secondary glazing that is designed to be both affordable and long-lasting. Contact us today for a bespoke quote.

Is Secondary Glazing A Good Idea?

Secondary glazing can offer many benefits to homeowners, including noise reduction, improved thermal efficiency, quick installation and enhanced security. Because we’re not replacing the entire window, it can be a cost-effective solution that doesn’t require permission, even on listed buildings. With so many options to choose from, secondary glazing can be perfect for most windows in a variety of different properties. Bellwood’s can help you through every stage of the process, from design to installation, so get in touch today to easily enhance your home.
