Saving in Laying Time

New clay tiles which result IN
construction savings of IS to 80 per
cent in laying time and labor, as
compared with ordinary masonry
wall and foundation materials, are
described in a research bulletin
edited by the structural service de-
partment of the American Institute
OF Architects from data provided by
the Producers Council.
Improved winter conditioning
units, steel windows which permit
better classroom daylighting, mov-
able walls and scientific kitchen
planning are also discussed.
The smooth, built-in handles of
the new tiles facilitate quick and
easy laying-one hand for the tile,
the other for the trowel," the bulle-
tin says. Dead air spaces in every
tile and mortar joint insulate
against rapid changes in tempera-
ture
water tests. in which water was
used in quantities which could never
be present under actual conditions,
revealed that basement walls con-
structed of these tiles prevent the
penetration of water from the ex-
terror to the interior"
New Attacks on Old Problems.
The use of gas-fired warm air
conditioning units opens new ap-
proaches to old heating problems, it
is pointed out. when the room
temperature drops, the room ther-
mostat responds, causing the units
controls to pass gas to the main
burners. The blower control, ther-
mostatically operated, acts only
when heat is supplied, so that only
properly tempered air and no cold
drafts are delivered.
when the room thermostat shuts
of the controls turn off the gas, but
the blower continues to operate
until all of the heat has been de-
lvered. All emergencies are pro-
vided. for by special controls. The
high limit control turns off the main
burners if the air temperature gets
too high. The thermostatic safety
pilot turns off the gas supply to any
burner in the event its pilot fails.
The motor overload control is pro-
lection against all forms of over
load, both mechanical and elec-
trical"
Steel-framed windows, which af-
ford larger glass areas, give better
classroom lighting, according to the
bulletin. Comparing two bay win
dbws in four sections, one framed
with wood and the other with steel,
1t was found that the steel win
dows have a % per cent larger ex-
posed glass area.
Additional Light Allowed.
"In the case of the wood windows
the glass line is 61z to 712 inches
below the ceiling. while in the case
of the steel windows it is but is
inches. Thus the steel-framed win
dows provide an important addi-
tional amount of direct sky light.
In total, the exposed glass areas of
the two types of windows are "a
square feet and 116 square feet, re-
spectively."
A new low-cost movable wall, easy
. to erect, is equally suitable for sub
dividing an overcrowded Office or for
partitioning off the departments of
q plant or factory.
The panels forming the finished
wall consist of a sealed core faced
on both sides with a a Inch facing
of an asbestos-ceme material.
These double-faced panels, 1s4
inches in thickness, are firmly an
chored to steel floor channels con-
cealed in the partition. The result
is lightweight, yet unusually solid
and durable wall, and one which,
because of it's simplified construc-
ton, can be easily and economically
erected. Relocation is equally rapid
and simple.
Exceptional sound resistance is
another feature of these movable
walls. They have sound isolation
value, as determined by exacting
comparative tests made on full-siZe
ceiling high units which is equal to
that of a 3-inch solid gypsum tile
partition.
Line of Accessories.
'The walls are made in both free
standing and ceiling high types, with
or without borrowed lights and with
q complete line of all necessary ac-
cessories, including hardware, metal
light frames, door bucks and doors.
Doors are of the same construction
as the wall panels"
Illustrating straight line produc-
ton" principles in scientific kitchen
planning, the bulletin shows how
efficient kitchen operation centerS in
four main areas: The receiving area
for food or supplies, centering around
the refrigerator and the necessary
storage cabinets: the preparation
and cleaning area, the axis around
which all kitchen work revolves, CEN
tering around the sink and storage
cabinets: the cooking and serving
area, which consists of space for
range and storage cabinets; the
planning area, where meals are
planned, recipes stored and groceries
ordered
"In the base cabinets of the re-
ceiving area are stored flour, sugar,
mixing utensils and baking pans,
also fruit and vegetables intended
= for immediate use. Canned fruits
are located in the less accessible
spaces. Wall cabinets should be in
stalled 18 inches above work surfaces
which are 25A inches deep. The
base cabinets are SO inches high
exactly the same height as the sink.
and a 4-inch toe space is provided
beneath all cabinets
