Steps
Feel the glass with your palm for ten seconds. If it is noticeably cold, the pane is losing heat and is a good candidate for this fix.
Clean the glass with a cloth and let it dry completely. Any dust or moisture film stops the bubbles from sticking.
Measure the pane and cut the bubble wrap about an inch larger on each side. Use half-inch bubbles, not thin gift-wrap bubble wrap.
Mist the glass lightly with water from the spray bottle. A fine film is enough to hold the wrap in place.
Press the flat side of the bubble wrap against the wet glass, bubbles facing the room. Smooth it from the centre out so it sits flat.
Check that the edges sit tight against the frame. Do not use tape, which leaves residue and can damage frames over winter.
Leave one window in the house uncovered, and skip any window that already shows condensation or mildew.
On a sliding glass door, cover only the fixed panel and keep the moving panel clear so the door still opens and closes safely.
Tips and common mistakes
Do not cover a window that already has condensation between the panes or on the glass, as trapped moisture can lead to mildew.
Keep one window uncovered for ventilation and never block a window you use as an escape route.
Check the wrap every few weeks and remove it in spring so the glass can dry out.
Questions
Does thin gift-wrap bubble wrap work?
No. Use large bubble wrap with half-inch bubbles. Thin wrap holds far less still air and gives little insulation.
Do I need tape to keep it up?
No. A light mist of water holds the wrap to clean glass, and skipping tape avoids sticky residue and frame damage.
Can I put this on every window?
No. Leave one window uncovered for ventilation and avoid any window with existing condensation or moisture problems.
