~ Background of the Invention 1040377
(1 ) Field of the Invention
This invention relates to a wall construct;on such as used in frame building
construction exterior walls and the like.
(2) Description of the Prior Art
Prior wall structures have uswlly employed wooden studding with flat outer
and inner surfaces and have locahd the insulating board or sheathing and the
lath and plaster or dry wall directly aga;nst the flat surfaces oF the studding as
seen in U.S. Patents 2,482,918 of Sept. 27, 1949 to E. J. Kump, Jr. and
3,318,056 of May 9, 1967 to J. H. Thompson. The first of these patents
utilizes insulation positioned in the cavities between the studding and the second
prov;dos grooved surfaces in the insulating board or sheathing and tho contruc-
ttons of both patents permit a relatiwly free hoat transfor between tho lath
and plastor or dry wall on tho inhrlor of tho~tudding and the insulatin~ board
or ~hoathing on tho oxtorior of tho studd7ng.
Tho prosont inventlon provides an exterior load boarlng wall wherein tho
Inner woll material, such as lath and plaster or dry wall, is supported in flat
contact with the studding so as to enable heat from tho inhrior lath and plasteror dry wall to move outwardly into the studding and heat the cavity in the wall
défined betweon tho studding. The transfer of the heat by the studding to the
oxterior insulated wall board or sheathing and siding is prevented by the
contouring of the exterlor surface of the studding through the formation of a
plurality of closely spaced transvene scallops therein. The exterior insulating
board and Its slding thereforo remain at exterior temperature and the inner lathand plaster or dry wall remain at room temperature with the cavities defined by
tho studding in the wall beina warmed by the heat flow through the studding which
act as heating fins therein.

~040377
A wall construction incorporating spaced vertical studding, the exterior
surfaces of which are provided with a plurality of transverse shallow scallops
in closely spaced relat;on to one another receives and isolates an exterior insulating
board and siding or the like with a miniumum of contact between the studding and
the insulating board. The inner or opposite surfaces of the studding are flat and
directly engaged against the lath and plaster or dry wall so as to conduct heat
therefrom into the cavit;es between the studding so as to form a warm wall isolated
from the exterior insulating board and siding thereon by very limited contact
therewith, the insulating board being unbroken and form;ng a weather, air and
10 moisture-tight exhrior wall.

Doscr;pt!on of tho Preforred Embodiment
By referr7ng to tho draw;ngs and F;gure 1 ;n particular, it will be seon that
20 a wall construct;on such as an exterior load bearTng wall has been disclosed and
whoreTn a sub-floor 10 or the like of a butld;ng ;s d;sclosed and supports a lowor
plate 11 with a plural7ty of studding 12 shnd;n9 vert;cally thereon in spacod
relation to ono another and extending upwardly and receiving a doublod upper
plato construction 13 on their uppermost ends. Each of the studd;ng 12 has a flat,
inner surface 14 and a contoured exterior surface 15 formed by a plurality of
closely spaced, transversely arranged shallow scallops 16, the lower plate 11, ;-
the doubled uppor plates 13 and the studdin5~ 14 are formed of two by fours as
20 known in tho art and the innor and outer two ;nch surfaces of the lower plate 11

and the doubled upper plates 13 are smooth and openings in the wall constructionas for example a window opening W as seen in Figure 1 is defin~d by smooth facedframing members 17. These framing members 17 are usually smooth faced studding
in the vertical sides of the window opening W and the sill portion of the opening
and are usually two by sixes or doubled two by fours bridging the top of the window
opening W
Still referr;ng to Figure 1 of the drawings, it will be seen that the framing
members 17 have smooth flat exterior surfaces just like the lower plate 11 and
the doubled upper plate 13 so that relatively thick insulating board 18 preferably
10 formed with a moisture-proof membrane 19On its inner side may be sealed along
its edges to the smooth flat surfaces of the !ower plate 11, the framTng members
17 about the opening Wand the smooth flat surfaces of the double plate 13. An
adhes7ve soalant which may be appl;ed with a caulking gun or the like forms
an effocttve seal as will be understood by those skilled in the art and they will
recogntze that the relattvely th7ck insulating board 18 is secured to the narrow
transverse flat surfaces between the scallops 16 of the studding 12 by fastenen
such as natls.
By referrtng now to Ftgures 2 and 3 of the drawings, it will be seen that
horizonhlly positioned lap siding 20 is shown affixed to the exterior of the
20 relat;vely thick insulating board 18 with a siding mounting strip 21 formed of a
reslltent plasttc material in accordance with my patent 3,ol8,668 of June 25,
1974 forming cushioned continuous closures between the overlapping siding 20
and the exterior of the relatively thtck insulating board 18 The sidirlg 20 is
athched to ~he wall by fashners such as nails preferably engaged through the
overlapptng portions of the siding 20 so as to engage the insulating board 18
and the studding 12 The construction forms a plurality of horizonhlly extending
vertically spaced air pockets between the interior of the siding 20 and the
28 exterior of the rolatively thick insulating board lô and results in an efficient

weather res;sting water-tight exterior wall having only very limited engagement
with the contoured surface of the studding on which it is supported.
In Figure 2 of the drawings the inner surfaces of the studding 12 which
are smooth and flat will be seen to directly support a lath and plaster or dry
wall 22 and that the same extends from the lower plate 11 to the doubled upper
,j plate 13 and is engaged thereagainst.
Still referring to Figure 2 of the drawings"t will be seen that the hmperature
of the lath and phshr or dry wclll 22 will Slenerally conform with that of the room
partially defined thereby in the bullding construction in which the invention is
10 used. It w;ll also be soen that this temperature will be conveyed by conhct
into the studding 12 and be dissipated from the larger sides of the studding 12
into the cavitTes dofinod therebetween so that a warm wall interior resulh.
Thoro ts llttlo or no travel of moisture from tho inner warm wall into the interior
,~ of tho wall bocau o it Is all at substantially tho same tomperaturo and the prosont
Invontlon th-rofoN prlmarily relatos to tho formation of an extorior bearlng wall
constructTon which is in internally warmod and which forms a weather and tempora-
turo barrior from tho oxterior thereof by reason of the siding 20, the air spacos
theroboneath and tho relatively thick insulating board 18and the moisturo barrier
'1 '
mombranco 19 thereon all of which is in very limitod conhct with the studding 12
20 by reason of tho plurallty of scallops 16 formed in the exterior surfaces thereof.
~ Ithough but ono ombod;ment of tho present invention has boon illustrated
and doscrTbed, It will bo apparont to thoso sklllod in tho art tha,t variou5 changos
and modifications may bo made thoroin without doparting from tho spirit of tho
Invontlon.
