What are the benefits of Economy Glaze DIY Secondary Glazing?
Whether you have white or dark windows the Economy glaze secondary glazing system gives you all of the thermal and acoustic benefits at a greatly reduced price. This magnetic secondary glazing also helps you to get rid of unhealthy and unsightly condensation.
Thermal insulation
Up to 48% of heat can be lost from the windows of even well insulated homes. This simple magnetic secondary glazing solution creates an airtight buffer between your existing window glazing and the glazing panel. This trapped air significantly reduces heat loss so your rooms stay warmer in the winter. This means that your heating bills are less as the rooms are easier to keep warm.

Reduce Sound transfer
Adding a DIY secondary glazing panel can reduce unwanted external sounds giving you a more peaceful home environment. Road noises among many other unwanted sounds can impact on relaxation and even sleep. The PET sheet works better than an additional glass sheet offering a less rigid surface that, along with the sealed air gap acts as a baffle. In essence some of the sound making its way through the first pane dissipates after bouncing off the second pane, reducing the amount of sound transfer. Read more in our Acoustic insulation Factsheet
Get rid of condensation
Condensation is unsightly and unhealthy moisture on the surface of your window. Not only does it obscure the view from the window but it also causes internal damage and rot to window frames and soft furnishings. Our customers are often amazed at how effective this simple magnetic secondary glazing solution is at eliminating condensation from their windows. Read more in our Condensation Factsheet
Why choose magnetic secondary glazing?
It is so affordable. DIY secondary glazing is a fraction of the price of double glazing and offers all of the benefits of more expensive systems.
There is no damage to your existing windows and no mess. You don’t need to make any messy changes to your existing windows. No drilling or screwing, no tools and no mess. The magnetic secondary glazing is fitted to your window frames with a narrow tape containing a contact adhesive backing. Your panel will have a magnetic tape around its edge and this fits easily and magnetically on to the tape on your frame.
There are no expensive fitting costs. This system is completely DIY. We have thousands of customers with little to no DIY skills that have fitted our simple magnetic secondary glazing system themselves easily and with great results. You basically stick one of the magnetic tapes around the outside of the sheet and its opposite tape sticks onto your window frame. For more information see our assembly and fitting instructions for White window frames or for Dark window frames.
Economy Glaze Secondary Glazing FAQs
What is the maximum panel size for the Economy glaze magnetic secondary glazing?
The specification of the tapes allows you to have panels up to 2m x 1.2m with tapes that are just under 13mm wide as long as the panel sits on a window cill to prevent slippage. If you have no cill in place then you can use our fixing clips beneath the panel or add a batten if you prefer. If the panel is on a mobile frame e.g a door then clips will be needed around the panel, these will also be needed if the panel isn’t vertical e.g. on a velux window.
