The Magnetglaze Secondary Glazing kit available right here at The Plastic People is one of the simplest and quickest ways to secondary glaze your existing windows without any planning permission or expense. Magnetglaze is an easy to remove magnetic secondary glazing system that provides cost effective heat and noise insulation, helps reduce condensation and still allows instant access to your window. This glazing kit consists of an acrylic window pane and 1 steel and magnetic tape. The tape is used to hold the acrylic window pane in position. This tape is supplied as a 5m long and 12mm wide coil. You can order DIY secondary glazing cut to the size or shape you need it. Simply enter your preferences and dimensions into the calculator above and get your secondary glazing quote today.
Secondary glazing works as an additional layer of glazing for your existing windows. If measured and fitted correctly, it will essentially form a double glazed solution for your windows - that in turn helps with heat retention, sound and condensation reduction and security. Plastic secondary glazing is a much more cost-effective alternative when you compare it to glass - and when you can cut it to any size or shape you need it to be - then installation should be a straightforward and safe process. Secondary glazing should always be fitted on the interior side of your window.
There are a number of reasons why DIY secondary glazing is a great investment.
First of all, you don’t need to replace your existing window pane to add secondary glazing yourself. This saves the cost you would incur when adding a double glazed glass window.
Again, if fitted and sealed correctly - secondary glazing will do a useful job of retaining indoor heat, protecting you from noise pollution and also make your existing window access more secure.You’ll also find that secondary glazing does a good job of preventing indoor draughts that could cause a chill.
We supply clear as glass acrylic for secondary glazing because it is lighter yet much stronger (17 x ) than glass and provides near perfect optical clarity.
We suggest at least 2mm acrylic, although 3mm and 4mm acrylic will give more rigidity and should be chosen for larger windows.
Enter the sizes you need for your secondary glazing pane above then select the number of rolls of magnetglaze tape you require. The magnetglaze tape comes in a pack containing 5m of white steel tape to attach to your window frame and 5m of magnet tape (with a white backing) to attach to your acrylic panel.
This provides easy, quick and cost effective heat and noise insulation too, along with instant access to the window making cleaning and ventilation simple.
Measuring up for our DIY secondary glazing is simple:
Measure the length and width of the glass window pane that you want to secondary glaze. Measure the visible glass then add at least 30mm to the length and width measurements. This allows for space to attach the magnetic tape to your window frame.
Enter your measurements into our Cut To Size Quote Tool above and complete your order.
Our simple DIY secondary glazing is straightforward to fit:
Hold the acrylic window pane up to your window so that it overlaps your window frame equally on each edge.
Using a pencil, draw around the acrylic window pane onto your frame. Now cut and stick the white metal strip of the magetic tape to your window frame - stick it just inside the pencil marks.
Finally, lift your acrylic glazing pane to the window and click into place.
Always fit your secondary glazing to your main window frame, not to the opening part of the window.
For windows such as 1000mm x 1000mm or bigger, we recommend you choose at least 3mm acrylic. This will provide you with more rigidity. We also recommend that you place a couple of screws immediately below the glazing panel to add extra support and to prevent the chance of slippage.
​For larger and draughtier windows take a look at stronger, Magnetglaze Extreme. This is essentially the same as Magnetglaze but with a wider magnetic tape to hold thicker acrylic glazing 4mm + in place and better cope with draughts from high winds. Magnetglaze Extreme contains magnetic tape sized at 10m long and 25mm wide.
Please check your existing window frame to see that you have at least 20mm of mounting surface available all the way round.
If you will need more than 5m of magnetic tape to fit around your plastic glazing pane please select the number of rolls you will need from our 'optional extras' menu above.
We do not recommend Magnetglaze plastic secondary glazing for sloping windows or ceiling/roof windows.
