Secondary glazing can provide a number of benefits. The biggest of these is heat insulation, but noise insulation, reduction in condensation, cost-effectiveness and others, with no compromise in appearance of your windows, are some of the reasons why Easyfix DIY secondary glazing systems are so popular.

For a rough guide of what thickness of plastic sheet to use on your size of window, bearing in mind that certain products have a restricted range of sheet (e.g. Trackglaze) but others offer a choice (e.g. Magnetglaze and Magnetglaze Extreme), we suggest these guidelines:

  • 2mm Sheet - Small windows - up to 1m sq
  • 3mm Sheet - Medium - 1m to 1.5m sq
  • 4mm Sheet - Large (1.5m - 2m sq) and Extra Large (2m sq+)
  • 5 or 6mm Sheet - use only with Magnetglaze Extreme products and Clipglaze
EasyFix DIY Double Glazing solutions are affordable, easy to install products for your home.
Save hundreds on installation cost by using simple products to mount Acrylic panels to your existing window frames.
Acrylic is a better thermal insulator than glass, and is 8x stronger so is a preferred option for insulation in homes.

EasyGlaze, TrackGlazeMagnetGlaze and MagnetGlaze Pro, can be used on both wooden AND aluminium frames. 
ClipGlaze and SuperGlaze, are screw mounting systems and are for wooden frames only.

We can supply you with the right amount of fittings and also can cut Acrylic panels to the correct sizes, all ready for you to install. Please see the Get a Quote page for instructions on how to measure and to request a free quotation.
