Bubble wrap is handy stuff indeed. It makes a great insulator that can be used in both Summer or Winter,
How does it work?
The most effective, affordable insulator is still air. Even your batts and blow-in type insulations rely on this. They are really just a matrix with hundreds and thousands of gaps, each filled with motionless air.
You can see that bubble wrap is similar. Different brands have different amounts of bubbles and different sized bubbles. These bubbles play the role of the insulator.
Also, plastic by itself is an insulator. Bubble wrap is really two layers of plastic pressed together in a way that allows bubbles to be formed. These layers act as an insulator too and have a different coefficient for conducting heat than glass.
On a more expensive scale, you can get acrylic sheets, insulating films and double or even triple glazing. These all work on the same two basic principles that bubble wrap as an insulator that give bubble wrap its properties. Of course, bubble wrap is much cheaper, if not free!
Great for renters
As there are no nails and there is no glue to hold the bubble wrap onto the windows, it is great for renters. Also it’s light, portable and easy to clean.
How to install bubble wrap
Bubble wrap can be wrapped firmly but not too tightly around almost anything. We even bubble wrap some of our potted plants in winter.
To apply bubble wrap, just follow these few easy steps –
Clean the window glass, wipe it over with a damp cloth, making sure that the glass surface stays pretty moist.
Press the bubble wrap lightly against the glass and viola! It stays there. This bond is pretty strong and the wrap will stay there until you pull it off.
If, for some reason, it does peel off, just add more water and reapply.
I like to use a single layer of clear bubble wrap so that it still allows plenty of light in. It’s up to you though, there’s even coloured wrap for you to make insulating, stained glass window coverings from.
