Cost of insulating
this wall: 13
per sq. ft., installed.
Simply pour water repellent
Zonolite Masonry Fill Insulation
into the cores of this 8" block.
That's all the wall needs to stay warm and dry
on the inside. If you don't want to finish the
nterior, you don't have to.
One man can easily insulate 29 square feet of
vall a minute with Zonolite Masonry Fill Insula
ion. To install it, he just opens the bag and pours.
"Either directly into the wall or into a hopper
hat can easily be knocked together on the job.)
He doesn't need to know any new techniques.
f he's smart enough to pour coffee into a cup,
me's smart enough to install Zonolite Masonry
Fill Insulation.
This insulation cuts heat transmission through
he walls up to 50% or more. Cuts the cost of
Your heating and cooling equipment, too, by
allowing you to use smaller units.
The material is water repellent. In tests at the
Structural Clay Products Research Foundation,
Geneva, III., it was installed in a cavity wall pur-
posely built to leak. The wall was subjected to
144 hours of rain-5" to 8½" per hour-at winds
up to 75 m.p.h. No water came through the
wall, or penetrated the insulation.
Another nice thing about Zonolite Masonry Fill
Insulation; when you pour it in, it doesn't get
hung up on mortar or reinforcement. Just fills
the wall right up and stays there without set-
tling, saving on heating and air conditioning bills
for the life of the building. For complete infor-
mation, read our Bulletin MF83. Write to Zono-
