 DIY extra window insulation using bubble wrap.

 This was inspired by an article on BuildItSsolar.com 



 This is one method of a semi permanent fixing of bubble wrap to UPVC window units and my not be suitable for your style of window.

I have only done this on a frosted window as the reduction in visibility is not an issue.

Images show after & before.

Step 1: What you will need

Picture of What you will need
A knife & sissers to trim the bubble wrap edges.
A scraper to prise out glass retaining strips & rubber weather strips.
A clean window.

Bubble wrap - not shown but it needs to be measured so that it is slightly larger than the glass with an inch or so to spare.

This works and is especially appropriate for privacy.

Bubble Wrap Insulation WORKS! There are easier and fancier ways to apply it, so do some searches before commencing. But no kidding, it really does save on energy consumption!

Your frame method looks easy to remove, I haven't cleaned my windows for ages..

I would now recommend putting some silica Gel at the bottom as I have started to get slight condensation build up between the glass & wrap.

Watch out for black mold, keep it under control with bleach.

I love this! Do you know how this would hold up to a blower door test? Georgia now requires them and I have a company coming over to preform it, and I wonder if this would help my rating. These are the guys that are doing it if that helps: http://www.americanenergysolutionsinc.com thanks!
