How do you fit secondary glazing? It’s a question many homeowners ask if they’re looking to enhance their living space. That’s because, while double glazing could improve your home, it can be quite complicated to fit. You’ll have to replace your existing window with a new design, meaning it’s a longer, more complex job to install double glazing.

However, with secondary glazing, you can add a new window to go in front of your old one. Because of this, it protects your old window’s appearance and performance, working with it to create a window that performs better than double glazing. And, as you won’t need to take your old window out, it can be easier to fit – even on your own!

Equipment To Fit Secondary Glazing

You could fit secondary glazing by yourself if you have some DIY experience. With some companies, you can choose a ‘supply-only’ option, meaning you’ll get the windows without paying for the installation, reducing the overall cost. Once you have the secondary glazing panels though, you’ll need some more tools to get ready to fit it.

These include measuring equipment, a hacksaw, clamps, scissors and the bolts, screws and screwdrivers you’d expect. With these, you’ll be able to measure, prepare and fit your new secondary glazing window. However, some equipment, such as a bradawl, may be more difficult to acquire.

Getting the right equipment to fit secondary glazing is crucial. That’s because, when you choose to install it on your own, you’re taking on the risk. Usually, the manufacturer of your new window will guarantee it in case their team does anything wrong during the installation. However, you assume the risk by fitting it yourself, meaning it can be a risky choice.

Preparing To Fit Secondary Glazing

Before you fit secondary glazing, it’s vital to prepare to fit it properly. To do it:

1. Use a steel tape measure to get the dimensions of the glass in your window – not the frames.
2. From there, add 25mm to each measurement to get the amount of plastic sheeting you’ll need, and trim it to that size to prepare to place it over the top of your old windows. When you cut the sheet, you’ll need to be careful and precise.
3. Use clamps to lock the sheeting in place to ensure the cut is arrow-straight, and a hacksaw to complete the cut by hand. If you want to use a power saw, make sure you set it on a slow speed, so you don’t melt away any of the plastic sheeting.

Making the right preparations to fit secondary glazing can ensure there are no problems during the fitting. Any errors with the measurements or cut could lead to issues, so being precise is critical.

Fitting Secondary Glazing

Once you’ve prepared it, it’s to fit your new secondary glazing unit. Once you’ve shaped the top of the window, you should make sure the edge is smooth and free from any discarded plastic. Then, fit magnetic strips to each edge of your new window, peeling off the protective paper as you go. At that point, you’ll be ready to put the glazing panel in place.

The glass can be heavy and difficult to prop up, so it’s wise to find an extra pair of hands to help you out. Adjust it until the sides of the sheet overlap evenly, then mark the edges to make putting the window together easier. From there, fit a self-adhesive strip on the pencil markings, and use tinsnips or heavy-duty scissors to cut the metal.

When all that’s done, you’ll be ready to put the windows together. However, if any part of the previous process isn’t quite right, it may not be air and water-tight. That could mean that wind and rain get through and still cause damage to your existing window, creating problems like condensation, draughts and dampness for your home.
