‘Did you break your windows”
‘Why have you got bubble wrap on your windows?’
‘What the hell are you up to now, Haines?’
These have been the three most common questions that visitors have asked over the last few months upon seeing the bubble wrap on the inside of the windows.
We’d heard that it helps to keep the heat in the house by adding a layer of cheap insulation to the glass.
Did it work?
We think it did. We don’t have data on kWh or dollars saved, but it did make a difference to our comfort level. The main thing we noticed was that we didn’t need a heater in the master bedroom at all, as its temperature was equal to that of the lounge (which is at the opposite end of the house).
With bubble wrap, the average difference was less than 1 degree centigrade, closer to 0. Thats not bad for free!
One of the great things about using bubble wrap on glass is that you only need to wet the glass with water, then press on the wrap. It stays on for the whole season with just that. No toxic glues or adhesives.
It’s a low tech winner!
