WALI CONSTRUCTION
Background of the Invention
(1) Field of the Invention:
This invention relates to wall construction such as used in
frame building construction exterior walls and the like.
(2) Description of the Prior Art:
Prior art wall structures have us~Ially employed wooden studding
with flat inner and outcr surfaces and havc located the insulating
board or sheathing and the lath and plater or drywall directIy aqainst
the flat surfaces of the studcling. A number of different wall construc-
tions have also been proposed in the past. See for example applicant's
(Joseph Charniga~ U.S. Pat. 4,031,681 of June 28,1977; U.S. Pat, 2,118,237~
G. S:Layer,et al of ~y 2~, 1938 and U.S. Pat. 3,611,653, D.L. ~Lnn of Oct. 12, 1971,
In applicant's patent 4,031,681 a wall construction is disclosed
having scalloped exterior surfaces of studding enga~ing the exterior
wall material. The inner surface oF the studding is flat onto which
drywall or lath and plaster construction is secured.
Ih U.S. Patent 2,11~,237 a partition is shown having studs with many
very small grooves in the stud ed~es thereby decreasin~ the amount of
surface contact with both the inner and outer parts of the wall structure.
In U.S. Patent 3,611,653 a sound attenuation wall partition is clisclosed
wherein a metal stud system has a series of projecting tabs so that the
interior wall is spaced with respect to the studs of the wall. The
tal>s are provided with foam pads.
The present invention provides an exterior load bearing wall wherein
the inner wall material such as lath and plaster or drywall is supported
in limited surface contact with the studding allowing circulation of
the air between the cavities normally formed by the studs. Additional
2~ vent openings are provided in the interior wall material and in the
--3--
~`
lower plate of the wall so that warm air can circulate witl-in the wall
cavity providing a warm wall interior. The limited surface contact
between the inner and exterior walls results from the formation of a
plurality of closely spaced transverse scallops in the studding. The
exterior insulating board, foam and siding therefore remain at the
exterior temperature with the inner heated wall being at room tempera-
ture.
Summary of the Invention
A wall construction incorporating spaced vertical studding, the
inner surfaces of which are provided with a plurality of transverse
shallow scallops in closely spaced relation to one another receives
and isolates an interior lath and plater or drywall material from the
exterior wall material with a minimum of contact between the studding
and the interior wall material. The outer or opposite surface of
the studding is flat and directly engaged against insulating board,
foam and exterior siding or the like so as to form the isolated
exterior wall. Openings are provided in the interior wall and in the
lower portion of the wall t
Air circulation is thus provided in the interior o-f the wall.

Description of the Preferred Embodiment
28 By reFerring to the drawings and Figure 1 in particular, it will
--4--
67~
be seen that a wall construction such as an exterior load bearing wall has
been disclosed and wherein a subfloor lO or the like of a building is
disclosed and supports a lower plate ll with a plurality of studding 12
standing vertically thereon in spaced relation to one another and extending
upwardly and receiving a double upper plate construction 13 on their
uppermost ends. Each of the studding 12 has a flat outer surface 14
and a contoured interior surface 15 formed by a plurality of closely
spaced transversely arranged shallow scallops 16. The lower plate 11,
the double upper plate 13 and the studding 14 are formed of 2 x 4's as
known in the art.
An insulating fiberboard 17 is positioned on the flat outer sur-Faces
14 of the studding 12 with a foam board 18 secured to the exterior surface
of the insulating board 17. Exterior siding l9 or the like is attached
to the foam board 18 by fasteners which pass through the foam board and
insulating board respectively to the studding 12. An interior wall 20,
shown as being formed of drywall, is secured to the studding 12 between
the transversely arranged shallow scallops 16.
Referring to Figure 2 of the drawings, a basement wall 21 is seen
supporting a joist member 22 onto which the subfloor lQ is resting.
A finished floor 23 is positioned on top oF the subfloor lO adiacent
the lower plate ll of the wall structure. A basement area 2L~ can be
seen to communicate with the interior of the wall construction throu~h
an opening in the lower plate 11 and subfloor lO covered with a fire
screen 25. Openings in the intcrior wall 20 have grills 26 and 27
secured thereon to allow the passage of interior air into and through
the wall structure. An insulating bat 28 is positioned within the wall
construction and is preferably of a type having a foil backing which
2~ provides a moisture and radiant insulating barrier. The insulation bat 28
_.5_
;7~
is positioned within the wall construction adjacent the exterior wall
insulating board 17 and is o-f a size that allows for an air space
be-tween it and the interior wall 20.
Referring now to Figures 2 and 3 of the drawings, it will be noted
that the temperature of the lath and plaster or interior wall 20 will
generally conform with that of the room partially defined thereby in
the building construction in which the invention is used. It will also
be seen that the circulation of warm air from the interior of the building
structure and the base~ent area 24 into the wall construction provldes a
cross flow pattern through the contoured interior surface 15 of the
studding 12, thereby circulating within the entire wall construction and
maintainin~ the interior wall 20 at the temperature of the room.
The dissipation of heat through the relatively small surface areas
defined by the contoured surface 15 of the studdina to the exterior wall
material is greatly reduced thereby increasing the insulating effectiveness
of the wall construction. There is little or no travel of moisture frorn
the inner warm wall to the exterior waTl because they are at substantially
the same temperature. The present invention therefore primarily relates
to the formation of an exterior bearing wall construction which is
internally warm and which forms a weather and temperature barrier from
the exterior thereof by reason of the siding 19, the air spaces there-
beneath and relatively thick foam board 1~ and insulatinrJ board 17 and
the insulating bat 2~, all of which is in very limited contact with the
interior wall 20 by reason of the transversely arranged shallow scallops
16 in the studding 12. This also stops sound transmission.
It will be understood that scallops can be formed in the inner surfaces
of the plates 11 and 13 so that the interior wall 20 is further isolated
2~ from the remainder of the wall construction.

Although but one embodimen~ o-E the present invention
has been illustrated and descrlbed, it will be apparent
to those skilled in the art that various changes and
modifications may be made therein without departing
from the spirit o:E the invention.
