Do I Need Planning Permission to Install Secondary Glazing?
Secondary glazing can be installed within the existing frame to reduce outside noise and cut down on energy costs. This is ideal for older homes and listed buildings, where replacing windows isn't an option.
It is also a great solution for damp buildings but only after other issues have been solved. This will stop draughts from preventing the building from receiving vital airflow.
Do I require planning permission?
The replacement of windows is among the most frequent home improvement projects that homeowners undertake. However, homeowners may be worried about whether they require permission for planning to install new windows. If you are replacing your old windows with identical ones and the work does not alter the appearance of your property it is not necessary to apply for planning permit. However, it's recommended to contact your local authority to verify prior to beginning any home improvement project.
The good news is that the installation of secondary glazing does not require permission to plan, nor does the draught-proofing process of windows that are already in use. This is because the addition of glass to the existing window does not affect the overall appearance of the building, nor does it change the dimensions or shape of the window. It is a convenient and cost-effective way to improve the thermal insulation of older buildings.
Secondary glazing isn't able to hold heat as efficiently in your home like a double-glazed window but it is excellent at keeping air from escaping. This helps keep your heating costs down. It can also reduce noise pollution. This is why it is a good option for homes close to airports, train stations or constructed areas.
If you are replacing or draughtproofing windows in a listed building, or a conservation zone, it may be necessary to get permission for planning. In this case, you will need to have drawings drawn by a reputable architectural practice to demonstrate that the planned work will be in line with the character and appearance of the building.
If you reside in a property that was built before the time of the Civil War the best method to increase the thermal insulation of your home without compromising the look of your windows is by using secondary glazing. This is because it has the same look and feel as windows of the past, but with the added benefit of being more energy-efficient and lessening noise pollution. Additionally, it is easy to install and can be removed at any time.
Can I install it myself?
If you are a DIY expert and your home has windows that are suitable, it might be possible to install secondary glass yourself. However, it's not an option for those who have no prior experience with window installation.
Secondary glazing is the precise installation of a second glass pane inside existing windows. This provides thermal and acoustic insulation as well as draught reduction and condensation control. It also provides additional security by acting as a non-intrusive barrier to potential intrusions.
To begin, determine double glazing installations of your window frame. This will provide you with the measurements needed to order a secondary glazing pane that's custom-made to fit. You can also purchase a secondary glazing kit that contains everything you require. These kits are available from a variety of hardware stores as well as online retailers. They differ in terms of quality and features. The cheaper options may include sheets of glass made of plastic and magnetic strips, while the more premium products will have authentic glass panes and seals.
After purchasing secondary glazing, clean and sand the window to remove any paint or varnish. To prevent damage to your new windows be sure to get rid of any debris, dirt or dust. You will need to move any TV aerials, telephone junction boxes or other structures that are connected to your window frames prior to when you can install secondary glazing. The majority of secondary glazing companies are able to cut the frame in a way that cables can pass through. They'll also supply you with cable clips to ensure a secure installation.
Install a piece insulation tape on the glass's secondary edge when you are ready to install. This will seal the glass. It's recommended to stick the tape onto the outside frame. This will give you a more professional look and will make sure that the secondary glazing is securely attached to the window frame.
Then, carefully position the second glass against your existing window and mark the positions for drilling. Remove the duct tape and drill through the holes that you have marked. Once the holes are drilled you can remove the duct tape and employ a damp cloth clean the frame.

Do I need a specialist?
If you're considering purchasing secondary glazing, it's essential to select a company that is registered with professional organisations and has a great reputation. Read online reviews and make sure you read both positive and negative reviews, and then ask friends and family members for suggestions. It is also important to determine if the company is registered with FENSA since this will ensure that replacement windows and doors are compliant with the building regulations in England and Wales.
Secondary glazing is a cost effective solution that can add an additional pane of slimline glass to your existing windows. It's designed to cut down on energy bills and noise pollution, making it a great choice for anyone wanting to lower their carbon footprint. The extra layer of glass can also help reduce air draughts, ensuring your home remains warm and comfortable throughout the year.
Secondary glazing is available in a variety of colors and finishes to match your home. Our latest range of products features ultra-slim sightlines that mean your new addition is barely noticeable from the outside. They can also be opened and closed according to the need for cleaning and to let fresh air into your home.
Unlike double glazing, which requires installing two separate frames secondary glazing is affixed to the inside of the window frame. It can be fitted using either reveal fixing or face fixing, with both offering distinct advantages in terms of thermal and acoustic. A professional glazier can advise you on which option is the best for you.
Many homeowners find secondary glazing to be the best solution, especially when they live in conservation areas or listed buildings that are not able to install double-glazed windows. It's much less expensive than replacing the windows and is easily removed if required in the future. It's also a great choice to prevent condensation which can cause damp and black mould, and also improve security, since it adds a barrier to the single-glazed windows.
Secondary glazing can be installed to fixed or sliding windows, and can be modified to suit the majority of styles. However, it's important to remember that it's not as efficient as double glazing at insulation of your home, as there's still an air gap between the primary window and the secondary pane.
What are the benefits of Secondary Glazing?
Secondary glazing is a cost-effective method to improve the insulation of acoustic and thermal of your home. It can be fitted to windows that are already in place, and based on the system you select it could also provide additional security. There are a range of systems available that can be used, including those for sliding sash window and those designed for uPVC frames. There are also systems that can be removed in summer to allow for more air to circulate.
One of the most significant advantages of secondary glazing is that it creates an insulating barrier, which stops loss of heat and cold drafts. This can lower your energy costs and make your home more comfortable. It's especially useful for older properties that have inadequate insulation, or for newly build homes with frames that are still moving.
Unlike double glazing, which requires the removal of your existing window, secondary glazing doesn't involve radical changes to your home. It's a less obvious solution that can be used with the windows you already have. It can be permanent or temporary depending on your needs.
Another benefit of secondary glazing is that it can reduce noise pollution, especially if your house is located close to a busy road or in a flight path. The twin brush seals that are found in the majority of secondary glazing systems ensure an extremely effective seal that can reduce noise by as much as 75 percent.
We suggest hiring an expert to install the secondary glass. This will ensure that the job is done properly and that you reap all the benefits you'd like to receive. Doing it yourself could result in gaps in the seal, improper fitting, and even damage to your windows.
It's crucial to remember that if you're going to make your own secondary glazing, it's essential to wear the proper safety equipment, especially when cutting glass. It is also important to ensure that you have all of the equipment and materials required prior to starting. Local companies can provide a better service and faster response times.
