I am looking for something to insulate the upper four feet of my basement
shop other than the fiberglas insulation I presently use. I don't want to
lose too much space in the shop to walls so I would like to find something
that has a decent "R" value and isnt that thick. What types of methods are
available? I have considered removing this insulation and just having the
poured concrete walls but don't know how much effect that might have on my
heating bill and comfort level.
Thanks in advance,
I insulated the outside of my foundation with ridgid foam insulation. My
foundation is exposed by about 18 inches, so I used 4 x 8' sheets horizontally.
So yes I had to do some digging, and I applied a concrete base brush on
material to cover the foam, and used some drip edge to cover the top. This was
approved by my utility company for basement insulation, and it does make for a
warmer basement, and smaller fuel bills.
Just my 2 cents.
What I have on the exposed concrete section of my workshop is a Dow product
called Polyisocynurate Insulation. It comes with a foil skin on both sides
and is available in various thickness's and R values
I put up a vapor barrier, then placed the insulation against it, and held it
in place with 2x4" fastened to the exposed studs of the interior walls,
insulated with fiberglass on the studded walls then covered it all with 1/4"
plywood held in place with exterior screws. And I never have to worry about
where I mount things on the wall.
I actually have two different barriers. My home is right next to the ocean,
and we get a lot of salt spray, and horizontal rain, so I have painted the
concrete with drylok waterseal, the foam, and then a vapor barrier, all
under the plywood.
