Sealing our windows was easier than I thought and helps the climate
I bought some foam tape from the store and lined all the window edges. It stopped the cold air from coming in RIGHT away. We're using less energy now, which is GOOD for fighting climate change. Plus, the house is much more comfortable.
That's the tough part about city living, some noises just cut through everything. Sealing helps with the general hum, but sirens have that direct piercing quality. You learn to live with it, but it never gets easy.
When we sealed our windows last fall, it was mostly for the draft... but then we noticed the kids slept better without the street noise. It's like that with a lot of home stuff, one fix solves a bunch of problems you didn't even think about.
