Magnetglaze Secondary Glazing Kit

The Magnetglaze Secondary Glazing kit  here at The Plastic People is one of the simplest and quickest ways to secondary glaze.

This glazing kit consists of an acrylic window pane which is held in position with a self adhesive magnetic tape.  No tools are needed with this method of secondary glazing.

How Magnetglaze Secondary Glazing works

Magnetic Secondary Glazing involves ordering supersafe acrylic window panes above.  We provide clear as glass acrylic for secondary glazing because it is lighter yet much stronger (10 x ) than glass and provides near perfect optical clarity.  We suggest at least 2mm acrylic though 3mm and 4mm acrylic can be used for larger windows to give more rigidity.  Enter the sizes you need for your secondary glazing pane above then select magnetglaze tape.  The magnetglaze tape attaches to your acrylic pane to hold it in place onto your existing interior window frame.  This provides cost effective heat and noise insulation too, along with instant access to the outer window.

To install Magnetglaze Secondary Glazing you will need

  • Your acrylic window glazing - order this above and we will be deliver it to your exact measurements
  • Magnetglaze tape. This comes as a 12mm wide strip with 2 parts: one 5m black magnetic strip and one 5m white metallic strip . Apply the metallic strip around your window frame using the double sided tape - it's white face will provide a neat appearance when your acrylic pane is not in place.  
  • Our kit comes is delivered with easy to follow instructions.   

How to measure & order your Magnetglaze Secondary Glazing Pane

  • Measure the length and width of the glass window pane that you want to secondary glaze. Measure the visible glass then add at least 25mm to the length and width measurements in order to have space to attach the magentic tape and fix to your window frame. 
  • Enter the measurements of your desired window pane size into the Cut To Size Quote Tool 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 clear as glass acrylic window pane.
  2. Hold the acrylic window pane to the existing window frame so that it overlaps equally on each edge
  3. Using a pencil draw around the acrylic 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 acrylic glazing pane to the window and click into place.  
  5. Always fit your secondary glazing to your main window frame, not to the opening part of the window.

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
  • For large windows such as 1200mm x 1200mm or bigger, we recommend you choose 3mm acrylic 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.

How many rolls of magnetic tape do I receive with each new window panel ?
You will receive 1 roll of magnetic tape with every window panel ordered. Each roll contains 5m of magentic strips.You can order more magnetic tape here if you would like additional supplies.
How should I clean my acrylic windows ?
We are often asked about the best way to care for acrylic glazing. 

Acrylic glazing can be cleaned with warm soapy water and a soft cotton cloth. 

No chemical cleaning products should be used on acrylic as this will lead to damage to the acrylic. 

Alternatively, we are very impressed with suitable cleaner Vuplex for a shiny, cleaner, more lustrous finish with no smears or smudges. It makes colored plastics vibrant, clear plastics virtually transparent and plastic paints gleaming like new.  Vuplex is a product which delivers fast quality results with minimal effort and fuss. It also protects new plastic from scratches and grime and restores plastic which has fine scratches and in ground grime. For this reason we sell it at a promotional price of £5.99.
How thick should my secondary glazing window pane be ?
2mm thick should be suitable for most windows, but 3mm or 4mm can be used for large windows to give more rigidity. Please not that Magnetglaze Sash is designed to work only with 2mm thick Polycarbonate or Acrylic  sheet.
Why do I need to add at least 25mm when I measure up ?
It is important that you measure the length and width of the glass window pane that you want to secondary glaze, measuring only the visible glass and then add atleast 25mm to the length and width measurements.    This additional minimum 25mm will allow you space to connect your new secondary glazing panel to your main window frame.  
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 are typically colder than the air in a room and therefore a noticeable place for condensation.  .On the face of it, because Secondary Glazing will have little effect on the airborne moisture in the home, it cannot solve condensation problems. On the other hand, because Secondary Glazing helps keep heat in the home which can cause less moisture to condensate, and by insulating windows (the most obvious place for condensation to occur) it certainly can reduce the worst visible effects
Will secondary glazing help reduce noise from outside ?
Opinions on the subject 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 make my home warmer ?
Yes, Secondary Glazing and Double Glazing should both prevent around 60% of window heat loss
Will secondary glazing work on larger windows ?
For large windows, such as 1200mm x 1200mm 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.
