Stop in for a cup of coffee

Well, I decided to fight the Black Friday crowds and go to HomeDepot and get the insulation panels for the garage windows. It wasn’t bad out there, just light traffic and normal volume of customers in the store. I left here, got the panels and was back home in 40 mins.

I spent the rest of the afternoon cutting and installing them. Three 4’x8’ R10 Owens Corning Foamular 250 panels cut to size and installed in about 2 hours. 54 sq. ft that was just R1 is now R11. It made an immediate difference. The garage temp went up more than 5* and more importantly, the temp 10” off the floor went up about 9*.

I installed them on the inside of the bamboo mini blinds so that from the outside it looks like it always did. They are completely removable and I should be able to use them for many years to come.

Right now it’s 37* outside, 12 mph NW wind blowing right at the garage and it’s 69* at my bench with the entire 2 car 9’ ceiling garage being heated with only an oil filled electric radiator at a 900w medium setting. :)

From time to time I look at house ads, most often with a basement, and almost always in areas where it is frost and snow in the winter. And it is one thing that puzzles me. In the ads with pictures from the basement, I almost never see insulation in the roof in the basement, which is the floor at the first level of the home. These puzzles me greatly, because our house here does not have a basement, but there is a crawl space under. I have never been there, but the floor is cold. So, now I wonder if it is no insulation here either, and I know for a fact that there is no insulation in the floor / roof between the first and second level.
Is this a common thing, not to have insulation in the floors in the US ? And if that is the case, for what reason ? I am used to 8 inches of insulation in the floors, 6 in the walls, and 14 in the roofs. Either a glass based insulation a bit like Owens corning, or Rockwool.
