Is Shrink Wrap Effective for Large Gaps in Windows?
Asked by SunnySkies84
I'm considering using shrink wrap to insulate my windows this winter, but I have a concern regarding the air gap. My windowsill has about a 12cm (5 1/2") gap between the window and the sill. Will this setup still be effective at keeping the cold out?

Have you thought about replacing the window instead? It might be a bit more upfront, but a single window shouldn't be too costly. Plus, it'll definitely give you better insulation long-term.

Using shrink wrap will definitely help, even with that gap. It won’t be as effective as if it were tight, since there's room for some convection, but it will still provide some insulation.

What exactly are you aiming for with the shrink wrap? Just trying to get something similar to double glazing on a budget? That’s totally possible!
ChillyNoMore: Yeah, I think that's the plan. Just a little extra help for the winter, nothing too fancy.
