window insulation

November 14, 2012 in Blog


I have noticed a lot more heat coming in my front window since removing the overgrown shrubs nearby which were effecting the growth of the rest of the garden. I have an awning which makes a difference, but have since put a second set of block out curtains behind the existing ones, and am now going to put some white bubble wrap on the window. Since I don’t have the curtains open, I don’t have to worry about staring at something effective but ugly, and I am sure it will make a noticeable difference.

  1. @Tracey It’s best if you block the heat out before it gets in the house. An outside blind is good for that sort of thing. Or anything that keeps the sun from hitting the glass.

    Bubble wrap should help, but what makes double glazing work is the air gap that’s trapped between the two sets of glass. I’ve heard that cling film works well, if you can fix it so that there’s air trapped in between the window and the
    film (cling film is essentially what’s used for the cheap alternative to double glazing).

    We use cling film on our skylight vents in summer and winter and it makes a huge difference – although that’s blocking airflow, not heat coming through glass.

  2. Interesting idea with the bubble wrap, hope it works out!

  3. There are some very useful topics on the Alternative Technology Association (ATA) forum regarding use of a film and other window treatments.

    Have a look here:

    Our house has only one (very small) wooden framed window, the rest are aluminium. I used the special cling film on that window and it was very easy to install.
