Author Affixing Fiberglass Insulation To A Wall
John Gregory

2005-12-12, 1:21 pm

I've got a fiberglass insulation problem. Picture the top room of a two
story house with attached garage having the top half of one wall (the garage
side wall) unsheathed exposing only one layer of R19 . with many voids. I've
placed three layers of R19 in the attic (atop this and other rooms) but the
exposure to the garage wall bothers me. I need to insulate it. From the
garage side, however, this top half of the wall is accessible from a loft
(garage ceiling). When standing in that loft and facing the wall that I want
to insulate, only about the top 4 feet of that room is exposed. The ends of
that wall taper off on an angle due to the slope of the roof. For some
reason a rafter on the top of that wall is marked "no sheathing" as though
it were explicit instructions to a carpenter not to cover that fiberglass. I
don't know why that would be other than to save time and a very small amount
of material. I suspect I'm loosing heat to the cold garage here in NE Ohio.
I want to add a layer of fiberglass to that exposed wall, running it
horizontally, but don't know how to affix it to the wall. Chicken wire is
the only thing I can think of at the moment. How do I wrap that exposed
wall?

tell us more about the target wall.

do you see studs? is it dried in already?

If it is just studded wall...why not just put regular insulation in
between the studs
and staple the edges of insulation to the stud (as usual)

if it is drywalled already...don't try to dump any insulation behind
it..pending the thickness of the drywall you could buckle the wall down
lower (i've seen this happen with the blown type)

Studs are exposed on the target wall and have R19 in between with a few
exceptions ("...unsheathed exposing only one layer of R19 . with many
voids..."). If I try stapling rows of R19 horizontally across these studs,
I'll be compressing the insulation to the point where I loose insulating
capability. The rolls need to be permitted to expand. To do that, the only
thing I can think might hold them in place that's practical and simply to
assemble is... chicken wire.

Use rigid insulation.

>>Use rigid insulation.<<
Can I get a minimum of R19 in rigid?

Depends on thickness, type of foam and your sensitivity to cost. This

Yes, use multiple layers if needed.

dude! never mind what it looks like (not that you said that)

don't add more insul over top of existing
fill in the holes and put plastic or a tarp over

or...hang to match existing ext finish

christmas is coming, plastic is cheap

Much like some people's advice.

WTF are you saying? The guy asks about putting more insulation on a
wall to bring it up to the insulation level for the rest of the room,
and you tell him to forget the insulation and cover it with plastic...?
Sheesh.

Rigid board is going to be R-5 per inch. Home Depot sells the 2" thick
stuff. Screw on the first layer with 3" drywall screws and washers and then
glue the second layer to the first. Alternatively you could call an
insulation supplier (yellow pages) and get 4" thick board. Leave a 1/2 gap
all the way around (makes cutting to fit MUCH easier) and then use a can of
Great Stuff to seal the edges.

Looks like "beadboard" is out: "... R-values range from 3.8 to 4.4 per inch
(2.54 cm) of thickness." This would mean I'd have to custom cut lots about 4
sheets and glue them together as opposed to running rows of R19 fiberglass
across a piece of chicken wire cut to the dimension necessary.

The chicken wire will compress the fiberglass and you'll get less
insulation value. If you want to investigate thicker rigid board, call
a roofing supply house. They'll have various types up to about 4"
thick.
