I am going to insulate my basement according to the building science
It is a full basement.
Do I need to glue up rigid insulation on parts of the foundation that are
not going to be framed up for the finish space ?
On the side of the foundation where the garage is, do I need to put rigid
insulation on that wall?? It is an attached garage.
Thanks for your time.
The local big box retailer (Menard's) sent out a sales flyer recently,
that had some rigid insulation, with preformed grooves for furring strip
type of nailers, specifically for basement walls.
This would allow for quick installation of the insulation, with the
ability to nail up the wall covering.
I can`t get your link, but I used R 7.2 " foamboard with Tapcons and
just painted it for easy removal incase of hidden mold growth. Sealing
it may be a nightmare in the future. Painted it looks good. Remember
there is 3.5 - 5 - and 7.2R foamboard insulation. Go 7.2 R
In rhode island, they are very, very sensitive now to foam insulation due to
the Station fire (which happened about two miles from my house ) Foamular
is very different than what they had on the ceiling at the club, but the
rules are followed to the letter now.
Thos idiots use foam for soundproofing and it was not a fire retardant type.
EPS foam and Styrofoam used for insulation is a modified material. It will
burn only when there is a source of ignition present. It will go out when
the source is removed. It is actually less flammable than may wall
decorations and curtains. It gives off carbon dioxide and soot when burned.
It is just smart to cover it.
Other rigid insulations may differ, may be more toxic.
It is usually not wise to insulate an unheated/uncooled space, such as a
garage, because natural breathing is slowed down and it stays hotter and
colder and might cause condensation. In the case of your basement, it's hard
to say because maybe it's a little bit heated or cooled. Look at the
Owens-Corning website and call 1-800-get-pink for free advice.
I read the document, and it appears to be outdated.
If your basement is dry, you can eliminate mold growth with spray in
foam. Because it bonds to the walls, moisture from the air does not
accumulate and there will be no mold growth. If the thickness of the
foam is adequate, moisture will not accumulate on the surface of the
insulation itself either!
While spray in foam is not cheap, there are cases where it pays
bigtime. Your basement begs for spray in foam!
Since the foam is expensive, you can lay in a thin layer on the wall,
place styro shets between the studs and then seal around the edges of
the styro with the spray in foam. This saves A LOTTA bucks and makes
the spray in foam price very reasonable.
The spray in foam does not burn, so it could be used as a bare wall
although building codes might require a wall covering.
Investige the profoam.com site, especially the r value myth and the
case study documents. They opened my eyes andn I've seen the light.
To do the job yourself, you can buy the faom in tanks and install it
easily although it will cost slightly more to do it this way. It does
free you from using contractors however:>:
