Happy to share. It’s funny you mention the colander…my friend was talking to me about the best way to insulate. He said that the biggest bang for your buck is to tackle the ceiling/attic first – that’s where the majority of heat losss occurs. He says he see people go out and buy theses super-expensive triple-paned windows and not do anything about their insulation. He said it’s like pluging one hole in the colander.

Cheers!

Our old house leaks heat like a colander does water
