Secondary window glazing is the addition of high quality acrylic PLEXIGLAS sheet to your existing single or double glazing windows. It is simple to install and is held in place using our magnetic tape system.

It traps a layer of still air between your existing window and the secondary glazing sheet. It gives you all the benefits of double glazing for a fraction of the cost of new double glazing windows.

It's a great option for people who want to retrofit their perfectly good windows.
