That’s not as large of a purchase as you’d think since we have just three proper windows. We also have a glass brick window (three bricks wide and three tall, so it’s a rectangle) and we have our back door which is nothing but glass.
The windows dated back to when this brownstone was renovated, or possibly to the second round of renovations. Regardless they were at least 20 years old and probably older so they did very little to keep out the cold or the heat, had no storm windows and no screens either.
We'd ordered the windows right before we flooded, and they got replaced during the reconstruction. Even then, before we were able to move back in, we could tell how much more efficient the new windows were and are.
So that’s a passive bit of winterizing we do. The active bit involves our stairs to the first floor.
Our second entrance is at the top of the stairs, which leads to the street level door. When we do use that door, we have to unlock our door, the common foyer door (which has two locks) and the iron gate (all that takes two keys). Yes, this is the same common foyer that the Ferals like to store extraneous microwaves and dressers in. Apparently they do not understand what being a good neighbor means.
So I’ve hung the curtains to enclose the stairs. It’s surprising how much difference those two el cheapo curtains from Ikea make. Not only does the heat stay downstairs where it belongs, I also don’t feet a chilly breeze coming down the stairs.
