When the mercury drops to zero
and below and the householder
spends lot of time stocking his fur
mace to keep the house warm he
wishes he had insulation in his home.
His wishes are fervently renewed
when it comes time to pay the coal
bill.
Insulation is to house what
blankets and comforters are to a
led. They aren't warm in them
selves but they make easier the bus
mess of keeping warm.
Because of the rigors of winter in
this climate and the fact that the
sun shines for long hours in sum-
mer. insulation is imperative to COM
fort. No conscientious builder would
recommend leaving it out of home
and yet there are houses in Bismarck
without it.
Briefly stated the argument for
insulation is that it makes the house
warmer in winter and cooler in sum-
nler; that it saves shoveling coal
and cuts the coal bill. The makers
OF balsam wool and thermofill, the
insulation used in the Demonstration
home, claim that it cuts the cost of
coal enough in two winters to paw
for itself and after that the owner
uses it free.
Warm As Wool
Balsam wool is a wood fibre prod
uct, treated to make it fire resist
ant and arranged in sheets SO that
1t can be nailed to the walls of the
house. Tests by the government
show that it is practically as warm
as wool blanket of the same thick
ness, and it is an inch thick. It
keeps the cold from penetrating the
walls in winter and keeps out the
heat IN summer. 1t obtains it's effec-
tiveness by millions Of dead air cells
which make it non-conductor of
heat or cold.
Insulation for the ceiling is gypso-
fill. a patented mixture Of gypsum
and fiber. 1t is permanent mater
ial and fireproof. It is commonly
used In ceilings because it is placed
between the joists or rafters and is
easier to apply than most other ma
terlals. Since a great deal of the
heat generated in home goes out
through the ceiling in winter, and
the roof gets hot in summer, ceiling
insulation is even more important
than wall insulation, according to
many builders. Both are worth their
cost and more.
In addition to the patented insul-
atoms the Demonstration home has
three coats of building paper. which
also serve as insulation. Two of
these are asphalted black building
paper. The third is Rhinorop, pat.
ented building paper built up of sew
eral thicknesses with a tar prepar-
alton in the center and cords placed
through it to make it tough.
Wood Permits Cold
The job assigned by the home
builder to this material is to assist
the insulation in making the house
lmpervious to heat or cold and to
keep out the wind. Tests show that
wind pressure has some effect inside
a water tight wooden box, due to the
tact that wood is porous and lets
small quantities of air pass through
1t. Paper is less porous and the tar
preparations make it practically
wind-tight.
The shingles on the house are of
asphalt composition with granite
face and varicolored, lending a pleas
ing effect to the roof. Wood
shingles may be used and from some
standpoints are desirable but the
permanence of asphaltic shingles,
their attractiveness and the ease Of
laying them properly causes them
to be widely used.
The shingles were supplied fol-
the Demonstration Home by the Bis
marck Paint and Glass company.
The insulation was sold by the Cen
trail Lumber company.
