Basement Insulation Thoughts...(Fiberglass and XPS?)
So, this weekend I spend about 20 hrs installing 2" XPS on the walls of my 800 Sq. Ft. Basement. I did the rim joists, I did the 2" and I used Great Stuff to seal it all together.
The plan is to use 1 inch XPS on the floor under plywood and then laminate flooring on top of that.
The plan is also to build 2x4 walls with sheetrock and electric.
I wasn't planning on installing fiberglass in the walls, but I wanted to run it by you good folk here on what you thought would be the best course...I mean, I definitely have the room for it, and if I don't use it, the 2x4 wall cavity will remain empty.
So I just researched Roxul a bit and it looks pretty solid.
I wanted to ask the good folk here though:
My basement i s 90% underground on 3 walls and 1 wall is 90% above ground (daylight basement, I think they call it).
I put the 2 inch poly on the walls and plan to 2x4 over it and wasn't planning on putting additional insulation. But...part of me wonders why I wouldn't. What is the general consensus? Should i do all the walls? Just the top of the buried walls? Just the open wall?
Hm, really good question. Basement insulation can always be tricky, but I don't think it can ever really hurt if you have the space (and money) for it. If you're looking for a full seal/insulator, take a look at --------. It's easy to use and easy to clean, otherwise I'd be curious to hear what others have experienced with basement insulation.
