In tills case plastic sheeting

The ceiling in a new home
or extension should be in-
sulated to at least R20. This
means at least 6 inches of
batt, blanket or loose -fill
insulation, and an effective
vapor barrier on the lower
(warm) side of the insulation.
The extra cost of a good in-
sulation job will more than
pay for itself over the life of
the house.
Your walls are the second
most important source of
heat loss. Aim for a total wall
resistance of R14 or more.
This means an R factor for
the insulation of at least 12,
about as much as can be
achieved with batts or
blankets and 4 -inch wall
studs.
If your plans permit ex-
tensive renovation, remove
the wallboard or plaster and
re -insulate the wall as you
would a npw one (see in-
structions below). Then
replace the wallboard. While
you're at it, you might want to
attach 1 x 2" or 2 x 2" strips to
the stud edges to allow for
more insulation in the wall
cavity.
To avoid the trouble of
removing the inside surface
of a wall, or when this can't
be done as with masonry
walls, you can apply new
insulation (batts, blankets or
rigid panels) to the inside
surface. Apply straps to the
wall to attach the insulation
and covering wallboard.
(Remember the styrofoam
should be covered by plaster
or gypsum board.) You can
use. 1 x 2" furring strips for
thin styrofoam; use at least 2
x 2" strips for batts, blankets
or thicker foam. Once your
strips are in place, apply the
insulation according to the
instructions below for frame
walls.
If • you have hollow, or
almost hollow,wood-frame
walls you can have a
professional insulation
contractor blow in loose -fill
insulation. He can do this
from the outside if small
sections of the exterior can be
removed, as with clapboard.
HERE'S HOW HEAT ESCAPES
FROM YOUR HOUSE
If the exterior is brick,
aluminum siding or stucco,
he'll have to drill holes in the
interior walls and repair
them when he's finished.
Care must be taken that the
entire stud space is filled
that no projections or -cross-
braces hinder the filling
process.
The cavity in older wood -
frame houses and in some
masonry walls can be filled
with a foamed -in-place. in-
sulation, such as urea -
formaldehyde. This must be
done by a professional. Check
the prices in your area and
pick the contractor carefully.
When you're insulating new
walls, the idea is to put in as
much insulation as the stud
space will accept. For extra
insulating value, consider 6 -
inch studs or a layer of
styrofoam sheeting on the
outside (under the exterior
surface). Follow the in -
