DIY window insulation

A simple method for adding some much needed insulation to a window whilst allowing the light in.

You will need:

  • Bubble wrap
  • Spary bottle with water
  • Box cutter knife


Clean the inside of the window and spray with water.

Place the bubble wrap on the wet window with the bubble side towards the outside. The bubble wrap will stick to the window.

Use the box cutter to cut the bubble wrap to fit.

It works surprisingly well and lets plenty of light through.
