Hello,
I have a bay window in my living room. Is it normal for the floor of the bay window to be cold? I ask because there's a really noticeable difference in temperature when you walk on the floor that has the basement under it to the part of the floor that sticks out.
Thanks,
Chris
Yes, fairly normal. There is less insulating structure under the bay part of the window.
You may be able to add some insulation under the floor part from outside underneath.
When I installed a large 5 light bay window, I put 2 layers of 3/4" foam on the bottom, outside. I had the aluminum guy cover it over. The floor of the window is not too bad (Chicago area) but it is still cool. One thing that can work is carpeting. I once carpeted the floor of another bay window and it always felt warmer.
Right now the living room floor is hardwood. I'll wait till spring or summer before I check the insulation or foam.
Thanks for the tips,
Chris
