Magnetglaze Extreme Magnetic Tape is designed specifically for larger acrylic panels and particularly draughty windows where extra grip is required. This additional support is provided via 25mm magnets and steel which combats the weight and impact of high winds. The Magnetglaze Extreme tape is sold in 1m lengths and is a stronger version of the standard Magnetglaze Magnetic Tape, which is better suited to smaller panes.

This is an effective product for installing secondary glazing using acrylic sheeting and also works well to insulate the home and keep outside noise at bay. On an aesthetic level, the tape is unobtrusive and can be made even smarter by using a finishing trim as well.

How is Magnetglaze Extreme Magnetic Tape Used?

Magnetglaze Extreme tape is easy to use and comes in coils of adhesive steel and magnetic strips which can be cut down to size easily. Measure your window frame to the point where the inside edge of the steel tape will be placed on the window surround for your vertical and horizontal measurements (be sure to check there’s a 20mm minimum mounting surface on all edges before starting the installation process). Add 25mm to these measurements for the size of acrylic panel you’ll require.

Clean the surface you’ll be affixing the tape to, to make sure it has been fully degreased, and then stick the magnetic take into position on your acrylic pane. Hold the panel over the frame and draw around the sides so you know where to fix the metal strip to – place it just inside of your pencil markings. The sheet can then be clipped into place over the top.

Can Magnetglaze Be Used with Other Products?

Magnetglaze Extreme tape looks great on its own, but you may prefer to use a finishing tape alongside the magnetic tape which will mask the cut edge of the sheet and the tape, if required. This can be mitred to give a more professional finish.

Your delivery address doesn’t need to be the same as your billing address. You can pick different addresses whilst checking out.

You are also more than welcome to come and pick your acrylic up from us. Our address is Unit 30, Mackley Industrial Estate, Henfield Road, Small Dole, BN5 9XR.

We will email you confirmation of your order, including your order details, your order number and the price that you have paid.

When your delivery is ready for dispatch, we will email you. This email will include the courier’s tracking number where possible. If you have ordered a smaller piece of acrylic, you will receive a notification from the courier detailing roughly when your order will be delivered on a specific day. If you have ordered a larger piece of acrylic, you may not receive any notifications from the courier, and unfortunately our courier also can’t specify a delivery time. If you are out, the courier will leave a card to allow you to arrange a new delivery time to suit you.

Due to factors beyond our control, we can’t guarantee that orders will be delivered when specified during our communications with you.

Your order should arrive packaged and in perfect condition, just as it left us. It will come with a layer of protective film over each surface (mirrored acrylic only has protective film on one side). If your order appears to have been damaged in transit, please refer to our Orders Damaged in Transit information.

We reserve the right to charge extra delivery costs if the dimensions/format of your order require us to use a specialist delivery company. 

We can arrange for delivery on Saturdays/before midday, please contact us for more details. There will be a supplement for these services.

There is a supplement on deliveries to the Scottish Highlands, Grampians, Northern Ireland, Eire, Isle of Wight, Isle of Man and the Channel Islands. This supplement will be calculated when you add your delivery details to your order.

If you have any questions please contact us by calling 01903 389 024 or email info@cutmyplastic.co.uk.


What tolerance do you cut to?

We cut to a tolerance of +/-3mm.

What is your delivery timescale?

3-7 working days.

Is mirrored acrylic like normal mirror?

Mirrored acrylic is a flexible material, and needs to be attached to a perfectly flat surface. We recommend attaching it to MDF or something similar, making sure the adhesive is spread in a thin even layer across the acrylic. we also recommend using the 5mm thick acrylic as it is more rigid.

Can you cut any shape?

Yes, in acrylic. We will shortly be able to also cut any shape in polycarbonate as well.

What's your standard radius corner?

20mm, but we can cut to your requirements.

How many holes do I need in my acrylic?

1 per corner should be sufficient for smaller pieces. You might want to consider an extra hole in the middle if your sheet is larger.

Can I cut acrylic?

Yes, you can. Just take it slow and easy.

Can I put acrylic behind a hob?

Not if it is gas or electric. You need a gap of 5cm between an induction hob and the acrylic.

Do you fit the acrylic?

No, we don't. We do provide some templates which should help you to take your measurements. The acrylic is easy to install by any competent DIYer.

What's the difference between acrylic and Perspex?

Perspex is a brand name. It is the same as acrylic.
