Magnetglaze Double-Glazing Kit

What our





out of


Hi, I wrote to you last night worried about getting the sticky tape off the edges of the perspex. I have solved the problem! You may want to include the instructions below for other users. What to do if you get Magnetglaze tape onto the wrong place on Acrylic Sheet Having dropped a bit of the cut off tape onto the acrylic, and then put it onto the wrong side of the acrylic sheet for sash windows, removing it was a problem at first. I pulled off the tape, which leaves about half the spongy material that backs the magnetic (or steel) tape. I first shaved off as much of the spongy material as possible using a craft knife parallel to the surface of the acrylic sheet, and then put Sticky Stuff Remover along the ribbon of material and left it to soak for about 1 hour. Then peeling off the sticky ribbon very carefully - pulling it back on itself as far as possible minimised the breakage of the tape - I was left with an almost clear edge, and any residue was easily cleaned with a bit of kitchen roll and some more Sticky Stuff Remover. What a huge contrast with trying to get the tape off too quickly which caused the glue to spread everywhere! (We got Sticky Stuff Remover from Lakeland Plastics. I don't know how widely available it is otherwise. I suspect that the 5-7 minutes recommended on the bottle might not be long enough.) I have not experimented with removing the tape without removing the spongy material. I will send feedback on the final double glazing effort when it is completed, but I did not want to put you to extra trouble to find me a solution. Yours Phil Bowers

Magnetglaze Secondary Double Glazing Kits

The Magnetglaze Secondary Glazing kits here at The Plastic People represent the simplest and quickest way to secondary glaze.

This is because no tools are needed with this method of secondary glazing.

Each of our Magnetic Secondary Glazing kits includes supersafe polycarbonate window panes which have been chosen because they are lighter yet 200 x stronger than glass and provide near perfect optical clarity. This kit provides cost effective heat and noise insulation too, along with instant access to the outer window.

In the Magnetglaze Secondary Glaing kit you will find

  • Your polycarbonate window glazing which will be delivered to your exact measurements
  • 5m roll (10mm wide) of white self-adhesive strip. The strip has 2 parts: one 5m black magnetic strip and one 5m white metallic strip 
  • Easy to follow instructions.   

How to measure / order your Magnetglaze Secondary Glazing Kit

  • Measure the length and width of the glass window pane that you want to secondary glaze. Only measure the visible glass then add 25mm to the length and width measurements.  
  • Enter the measurements of your desired window pane size into the Made To Measure box above.  

Fitting is quick with our  secondary glazing products- all you'll need is a pair of scissors, a tape measure and this simple step-by -step guide:

  1. Cut and stick the black magnetic strip  to the edges of your new polycarbonate window pane.
  2. Hold the polycarbonate window pane to the existing window frame so that it overlaps equally on each edge
  3. Using a pencil draw around the polycarbonate window pane onto your frame. Now cut and stick the white metal strip to your window frame - stick it just inside the pencil marks.  
  4. Finally, lift your polycarbonate glazing pane to the window and click into place.  
  5. For more information download our Magnetglaze Fitting Instructions


For large windows, such as 1200mm x 1200mm or bigger, we recommend you choose 3mm polycarbonate. This will provide you with more rigidity.  Place a couple of screws immediately below the glazing panel to add extra support and to prevent the chance of slippage.


Important Notes:

  • Please check your existing window frame to see that you have atleast 19mm mounting surface on each side of your window.
  • If you will need more than 5m of adhesive strip 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 or sloping windows
