Save heating cost in winter by insulating Glass Doors and Windows with bubble wrap & water spray
Save money on heating bills using cheap insulation with bubble wrap and spray bottle for doors & windows.
Bubble wrap is easily available on ebay, amazon etc. cut to the size of your glass windows and doors, just spray on the glass and one side of the bubble wrap and it will work like a glue but you can remove this whenever you want. Store it in the summer to reuse again next winter!
I've been using it on double glazed and my heating bill reduced by around 1/3rd. It will work great on a single gaze window too. Highly recommended if you live in a very cold area!
