The Extreme Magnetic Secondary Glazing kit is ideal for insulating larger or very draughty windows.
This glazing kit consists of a clear as glass acrylic pane which is held in position at your window with a self adhesive powerful magnetic tape (10m long, 25mm wide) - instantly attachable and detachable for great convenience.

Finding The Right Kit
For panels under a 4500mm perimeter we recommend our Standard Glazing Kits.
What is secondary glazing?
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, 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.
How effective is secondary glazing?
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, reduce condensation and 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.
How extreme magnetic secondary glazing works
We supply clear as glass acrylic for secondary glazing because it is lighter yet much stronger (17x) than glass and provides near perfect optical clarity.
We suggest at least 4mm acrylic, although 5mm and 6mm acrylic will give more rigidity.
Enter the sizes you need for your secondary glazing pane above then select the number of rolls of extreme magnetic tape you require. The magnetic tape comes in a pack containing 10m of white steel tape to attach to your window frame and 10m of magnet tape (with a white backing) to attach to your acrylic panel.
This provides easy, quick and cost effective heat insulation too, along with instant access to the window making cleaning and ventilation simple.
How to measure and order DIY secondary glazing
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 55mm 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.
How to install DIY secondary glazing
Our simple DIY secondary glazing is straightforward to fit:
- When your order arrives and you’re happy to start, begin by cutting and sticking the black part of the magnetic tape to the edges of your new clear as glass acrylic window pane. The steel and magnetic tapes both come in coils, so just measure off the length needed, cut and stick down into position.
- 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.
Is secondary glazing suitable for listed buildings?
- Because this type of secondary glazing does not require any planning permission it is an ideal solution for immediately tackling draughts and condensation in listed buildings.
Important considerations
- Please check your existing window frame to see that you have at least 55mm of mounting surface available all the way round.
- If you need more than 10m of Extreme Magnet please select the number of rolls from our menu above.
- We do not recommend magnetic plastic secondary glazing for sloping windows or ceiling/roof windows.

Secondary Glazing — FAQs
Will secondary glazing work on larger windows?
For large windows, such as 1200 mm × 1200 mm or bigger, you can place a couple of screws immediately below the secondary glazing panel to add support and prevent the chance of it slipping or detaching.
We recommend looking at Magnetglaze Extreme for larger windows. This kit is ideal for insulating larger or very draughty windows.
Will secondary glazing make my home warmer?
Yes, secondary glazing and double glazing should both prevent around 60% of window heat loss.
Will secondary glazing help reduce noise from outside?
Opinions vary, especially as much of the information about noise-reducing properties of windows comes from manufacturers themselves. A consensus is that single glazing with a secondary panel is a better insulator than double glazing, and likewise double glazing with a secondary panel beats triple glazing.
Will secondary glazing eliminate condensation?
Condensation happens when the moisture content of warm air settles on a colder surface — the colder the air, the less moisture it can hold. Windows are typically colder than the air in a room and therefore a noticeable place for condensation.
Because secondary glazing has little effect on the airborne moisture in the home, it cannot fully solve condensation problems. However, by keeping heat in and insulating windows (the most common place for condensation to occur), it can reduce the worst visible effects.
I need a specific size of plastic – can you help?
Yes, we can cut plastic to your specific measurements. Just key your measurements into our Cut to Size calculator for an immediate quote and to place your order.
How thick should my secondary glazing window pane be?
2 mm thick should be suitable for most windows, but 3 mm or 4 mm can be used for large windows to give more rigidity. Please note that Magnetglaze Sash is designed to work only with 2 mm thick polycarbonate or acrylic sheet.
How should I clean my acrylic windows?
Acrylic glazing can be cleaned with warm soapy water and a soft cotton cloth.
Do not use chemical cleaning products on acrylic, as this will damage the material.
We recommend Vuplex cleaner for a shiny, cleaner finish with no smears or smudges. It makes coloured plastics vibrant, clear plastics virtually transparent, and plastic paints gleaming like new. Vuplex delivers fast quality results with minimal effort and fuss, protects new plastic from scratches and grime, and restores plastic with fine scratches and ingrained grime.
How many rolls of magnetic tape do I receive with each new window panel?
Our Magnetglaze kits come with 1 × 5 m roll of magnetic tape (12.5 mm wide).
Our Magnetglaze Extreme kits come with 1 × 10 m roll of magnetic tape (25 mm wide).
You can order more magnetic tape at the same time as your panels if you’d like additional supplies.

Protective Films
All plastic sheet products will have a Clear, Blue or White protective film on both sides or a combination of all three. This is to protect during transit and needs removing before usage. Sometimes it can be difficult to peel off but use a thumbnail gently on any corner to lift and peel. Alternatively gently wet any corner with a cloth to separate film and peel.
Adhesives & Sealants
When using any adhesives or sealants with your plastic sheet product great care must be taken in ensuring its compatibility. Some products can react adversely and either not bond/seal properly or would cause the acrylic to cloud or become white at the bond line. Refer to our web pages for advice if unsure. Check your sealant/adhesives ‘use by date’ to ensure its still current for best performance in your project.
