SecondaryDIYGlazing - online suppliers of Easyfix DIY Secondary Glazing Systems and Draught Excluders
Our secondary glazing systems and draught excluders are extremely effective for heat retention and noise insulation, and are easy to install with everyday tools. To help you decide which to choose, what each looks like and how to install them, we have a range of videos that show this in straightforward steps, as well as printable installation instructions for each Easyfix DIY secondary glazing system. For glazing sheet, we recommend Polycarbonate as the best material, but we have a video both to compare the different glazing sheets available, and to show you their respective breaking strengths.
How Effective is Easyfix Window Insulation?
Thermal Image of a Part Insulated Room
In a typical room, the coldest surface will be the glass panes in a window, as these are cooled by outside air, reducing the benefit of heating inside the room. In the picture here, a customer has used a thermal imaging camera to illustrate just how effective Easyfix secondary glazing is.
The insulated walls are 22.5 degrees C
On the left, the window is 21.4 degrees, having been insulated with Easyfix Magnetglaze and plastic sheet
The window on the right has no insulation on it, and is 13.7 degrees. If this window were also draughty the effects of not insulating would be felt clearly in this part of the room
