Black Magnetic Secondary Glazing Tape

Magnetic glazing tape is an easy-to-remove tape that allows you to fix sheets of acrylic to your windows for a cost-effective and simple secondary glazing alternative to traditional double glazing. As well as insulating, our black magnetic glazing tape provides effective noise insulation and instant access to the window beneath.

We recommend using this to only fix acrylic sheets of thickness between 2 to 4mm, that measure no larger than a metre squared. Tape is 13mm x 5m, so there should be plenty for you to mount on a meter square window - order multiple quanitity for multiple or larger windows. Please consider the width of the tape (13mm) when measuring for the size of acrylic secondary glazing required.

The black magnet glazing tape comes in coils and can be cut at the required measurement for your project. To use, measure, and frame up to the point that the inside edge of the tape will be placed on.

Once you’ve measured the length you need and cut the specific amount of tape, clean and degrease the window frame using an appropriate preparation wipe or cleaner, and then stick the black magnetic tape into position on the sheet. We recommend using one of our microfibre cloths for this task.

The tape comes as two reels. One of which has a verticle groove down the middle of it. You can use this to make sure you have two opossing magnetic strips. One on the window frame and one on the acrylic sheet.

Hold the panel onto the window frame so it overlaps equally on all sides. Draw a pencil line around the sides of the sheet onto the frame and cut the strip to fit this, sticking it into place just inside of the pencil marks. You can then clip the sheet into place.

For larger sheets although magnet glazing tape works well on its own, we recommend either doubling up on the tape you use on the panel, or putting a few screws directly under the panel to support the weight and prevent the risk of slippage of the magnets.
