Topic tags/keywords: question

Hey, as you probably know I am in the prosses of building my new shop.
I was wondering what type of insulation you have in your shop and what your opinion is of it. I am thinking about using spray foam do you have any comments on this product?

Oh yeah there will be a blog update soon!

if you still havent put up the sheetrock on the framing – you’re better off going with the fiberglass-type insulation, it comes in rolls, is darn cheap (compared to the spray foam) and is much easier/faster to install than the spray foam as well. the good thing about the spray foam is if you already have the walls up on the frame, and need to insulate those – you can use the spray to get in the wall without having the remove all the sheetrock. (but that involves cutting relief holes to spray into the wall and patching those later…)

Hi Callum;

I would / did use rolls if fiberglass insulation. If you want to fish a wire later on, foam insulation will make it impossible.

Also, it is usually cheaper to hire a professional insulating company to do the job for you.

And much less itchy!

On my construction projects, it is often less money to have the job done, than I can buy the materials for!

Which makes me very happy.

Get a few bids and references, before hiring someone. Also, CALL the references! They aren’t much good if you don’t follow up!

Hope this helps;

I did the rolled fiberglass in my shop. Went quick and the shop is toasty in the winter so it must be working. 6” in the walls and 12” in the ceiling.

I too used roll type. r13 in the walls and r19 in the ceiling. Very cheap to do. Small shop only 16×20. 10k btu a/c for summer works great and small wood heater for winter is just right for our mild winters.

I used both rigid styrafoam and fiberglass for the best R rating…This desert gets hot in the summer and very cold in the winter….I love that pellet stove!
