Installing Insulation

In the images below show that different
types of insulation (spray foam, blown in
cellulose and fiberglass, and fiberglass bats)
were used to meet different requirements.

Above the dining room (vaulted ceiling).

Above the living room (north side).

Above the living room (south side).

Above the main bedroom closets and bath.

17.2" of cellulose insulation was placed above
the ceiling upstairs. Our vendor (MIFFCO)
claims that the ceilings will provide thermal
resistance of R-60. For comparison, the thermal
resistance of our ICF (foam block) walls is
expected to be R-24. This picture shows the
insulation above the main bedroom.

Insulation between the upstairs bedroom
and bathroom helps keep the bedroom
quiet. The two pink boxes are for bedroom
speakers.

This is the east wall of the living room. The two
empty wall cavities on the right are return air
ducts. The horizontal steel bars behind the
ducts are RC1 sound channel. They reduce
sound transmission from the drywall in the
laundry room to the studs, and thereby help
keep the living room quiet.

Insulation in this wall is especially heavy in
order to minimize the transfer of noise
from the laundry room.

The skylight has a thick blanket of spray foam
insulation.

The wall between the utility/furnace room and
the family room downstairs is filled with
cellulose insulation.

The south wall of the dining room has fiberglass
(pink) and cellulose (gray) insulation.

Here, Mike is spraying cellulose into the north
wall of the garage.

And, here he is filling up a wall
next to the laundry room.

Mike Bookbinder from MIFFCO was in charge of
the insulation project. He and his crew did an
outstanding job. Here, he is blowing cellulose into
the south wall of the stairway.

Nylon mesh netting is stapled to the wall studs
in order to create a cavity for blowing in
cellulose and fiberglass insulation. Fiberglass
is used between conditioned and unconditioned
(outside) spaces. Cellulose is used for interior
soundproofing and for insulating the ceiling
above the main level.

Cardboard spacers were installed just below the
roof to provide ventilation from the soffit to the
attic. That helps to prevent icicles from forming
on the eves.

One inch foam backer boards (pink) were
installed in the ceiling transition areas. They
hold the blown cellulose in place and provide
extra insulation.

We asked MIFFCO to install foam insulation in
all stud walls that separated the living area
from unconditioned space. The five cavities
on the left side of this wall separate the
stairway area from the garage. A second
wall, on the back side of this one, is full of
cellulose insulation.

Blown-in fiberglass insulation
increases the R value of the foam.

The back side of the west garage
wall has about an inch of spray foam.

Eleanor and I installed insulation in the basement
ceiling. The rest of the insulation was installed by
MIFFCO.
