Today’s tip is to insulate the windows of your home by simply attaching a layer of bubble wrap for winter.

What a BRILLIANT idea for all those basement windows, guest room windows, garage windows and other areas where complete sunlight & a clear view are not that important. This helps the whole house to stay warmer. It is also perfect for your greenhouse.

Use the wrap with larger bubbles for best look-through visibility and artistic effects.

1, 2, 3 How to Insulate Your Windows w Bubble wrap

Step 1: Measure your windows. This may take a minute or two per window.

Step 2: Cut pieces of bubble wrap to size.  This may also take a minute or two per window.

Tip: Want to be super-duper organized? Label or number each piece for easy reuse next winter.  If you number each sheet before you store it, you will need to also make a reference chart so you’ll know which goes where next year.

Step 3: Spray water on window and place sized bubble sheets onto window with bubbles facing window. Done.  It will dry all by itself and stay in position. Attaching the bubble wrap to the windows just takes 15 seconds per window.

Tip: Just peel it off when no longer needed and store bubble wrap for next year.

Where to Get Bubble Wrap

Simply Buy Bubble Wrap online.

First measure all your windows you would like to insulate. The large bubble wrap comes in 12” or 24”. So figure how much you’ll need in total first.

Then, have a quick look on the attic to see what bubble wrap you already have on hand.  You could ask local shopkeepers for bubble wrap packaging material that they are throwing away.  Usually, they have just smaller bits of bubble wrap however, and I’m sure that you do want to create a patchwork project out of this (wink).

So, back to my initial suggestion of buying your wrap online. Sometimes that is the fastest, most economical, stress-free and environmentally-friendly way of shopping. If you choose to use my affiliate link above to buy the bubble wrap, I would like to thank you as that helps pay for the cost in maintaining the blog and feed the cat.
