Bubble Wrap Insulation

Looking for cheap way to stop your precious heat being sucked through the glass of your windows? Well, there is a way…

Bubble Wrap. Yep, another use for nearly everyone’s favourite toy. Who hasn’t spent mindless minutes popping these sheets of tempting plastic bubbles?

How does it work?

You may remember that I’ve said that the best insulator is a pocket of still air. With bubble wrap you have two good insulators, plastic (the sheets) and air (the bubbles).

How to do it –

The other joy of using bubble wrap to insulate glass is the simplicity of application.

All you need to do is cut the bubble wrap to size, then wet your window with water. No toxic glues or adhesives, just water. Then you simply press the bubble wrap to the glass and make sure there’s no bubbles (a little irony here…) between the plastic and the glass.

Does it work?

Yep. We’re happy that it does. We don’t have any data on kWh or dollars saved, but there was a noticible improvement in personal comfort in all rooms so insulated. The main difference was in the temperature difference between the lounge and the master bedroom at the other end of the house.

This year, that difference was less than 1 degree centigrade with no heater in the bedroom. We’ve been using this temperature difference as an indicator since we had the roof fully sealed and insulated.

The improvements have been as follows –

  • before insulation:   4 degrees C with heater in both rooms
  • after insulation:       1 degree C with no heater in bedroom
  • with bubble wrap:    close to 0 with no heater in bedroom

There it is, a low tech solution to some of your heating problems!

Now its time to take it down.
