WAL,L LINE INSULATION PILLOWS
BACI~ROUND OF THE INVENTION
This invention relates to new and useful improve-ments in insulating pillows for insulating the wall line area or junction between a vertical wall and the sloping roof. Adjacent roof rafters and ceiling joists, where they rest upon the upper plate of a vertical wall, forms a wedge-shaped recess beyond which is usually provided a soffit area.
It is normal to insulate an attic area by the use of blown or loose fill insulation supported by the ceiling panels attached to the underside of the ceiling joists and in order to get the necessary ~ value, a considerable thickness of such insulation is required.
While this is no problem over the major area of the attic floor, nevertheless as the wedge-shaped recesses are reached, the thickness of the insulation necessarily decreases thereby causing a situation where -the P~ value also decreases from the desired amount.
When using loose fill insulation, it is also necessary firstly to prevent same from being blown or dis-; placed into the soffit area and perhaps blocking the air intake thereof and also to provide an air passageway from the soffit area to the free air area above the insulation ; within the attic area.
~79~7 SUMMARY OF THE INVENTION
The present device solves all of these problems by providing a wedge-shaped pillow formed of an insulation material having a relatively high ~ value so that the ~ value of the insulation is maintained to the outer surEace of the vertical wall. Means also may be incorporated which main-tains an open air passageway between the soffit area and the free air area above the insulation so that the necessary circulation of air may take place thus preventing condensa-tion occurring.
Vent and baffle units are well known and exam-ples include U.S. Patent 4,214,$10 which shows a vent and baffle unit made from a sin~le thickness of material. U.S.
Patent 4,223,489 shows an insulation stop which once again merely prevents insulation from passin~ into the soffit area but does not add to the insulating value of the structure.
U.S. Patent 4,237,672 shows a roofing vent with an installation tool and 49184,416 shows a combination of thermal insulation stop and ventilation baffle. U.S. Patent 4,185,433 shows an insulation baffle and U.S. Patent 3,863,553 shows a combination insulation stop and ventilating baffle.
However, none of these are formed frfom an insula-ting material ~ se which not only acts as an insulating stop and baffle but also maintains the necessary insulating ~'7~7 value to the outer surface of the vertical wall.
In accordance with the invention there is pro-vided a wall line insulation pillow locatable within the wedge-shaped recess defined by adjacent roof rafters, roof panels extending therebetween and adjacent ceiling joists and ceiling panels therebetween, said pillow maintaining the insulation R value between attic insulation and the outer surface of the structural wall; comprising in combination a substantially wedge-shaped block of insulating material having a substantially rectangular face, a substantially rectangular wall extending upwardly from one edge of said face, spaced and parallel side walls extending upwardly from said face and a further face extending from the distal edge of said wall to the other edge of said face with the thickness and hence the R value of said pillow increasing from said other edge of said face towards said substantial-ly rectangular wall, said pillow, when in situ, being situated with said one face forming the base thereof and engaging between adjacent ceiling joists and upon the associated ceiling panel and air vent means being formed through said other face from the front to the rear thereof.
In accordance with another aspect of the inven-tion there is provided a wall line insulation pillow for location within the wedge-shaped recess defined by adjacent roof rafters, roof panels extending therebetween and adja-cent ceiling joists with ceiling panels therebetween, com-~75~7 prising in combination a wedge-shaped block of insulating material engageable within the associated wedge-shaped re-cess whereby the R value of said pillow increase from the inner end of said wedge towards the thicker end thereof and means to maintain said pillow in position.
A yet further advantage of the invention is to provide a device of the character herewithin described which is simple in construction, economical in manufacture and otherwise well suited to the purpose for which it is designed.

D _ I~.ED DESCRIPTION
Proceeding ~herefore to describe the invention in detail, reference should first be made to Figures 1 and
2 in which reference character 10 shows spaced and parallel ceiling joists having a ceiling panel 11 secured to the underside thereof in the usual way. Said panel may be of a dry wall construction, plywood, or any other well known material.
These ceiling joists rest upon the upper hori-~379!6~
zontal plate 12 of a vertical wall shown schematically at 13 and spaced and parallel roof rafters 14 also rest upon the plates 12 one adjacent each ceiling joist 10. Convention-ally, the roof rafters incline upwardly and inwardly from the upper side of the vertical wall 13 thus defining a wedge-shaped area 15 between adjacent joists 10, adjacent rafters 14, the ceiling panel 11 and a corresponding roof panel 16 spanning the upper sides of the roof rafters. The roof rafters normally extend outwardly beyond the outer side 13A
of the vertical wall with a soffit panel 17 extending in-wardly ~rom the extremities of the rafters to the outer sur-'7~ 6 face in a conventional manner. Such soffit areas or panels 17 normally include ventilators 18 at spaced intervals to permit air circulation through the attic area indicated by reference character 19.
In climates requiring the upper side of the ceil-ing panels 11 to be insulated, it is conventional to util-ize a standard loose fill insulation indicated by refer-ence character 20 and this insulation may take the form of fiber, loose rock, wool or the like. It is either poured or blown into position between adjacent joists 10 to a suffi-cient thickness above the joists to give the necessary insu-lating R value.
No problem is encountered in placing a sufficient thickness of insulation over the majority of the attic floor but as the wedge-shaped areas are encountered, it is obvious that the thickness of the insulation must decrease to prac-tically nil adjacent the outer surface 13A of the outer wall 13. This necessarily decreases the R value below the de-sired figure. Furthermore when such insulation is blown into position, it often extends between adjacent roof rafters and into the soffit area and may even 'Dlock the air intakes 18 thus preventing the desired circulation of air.
The pillow collectively designated 21 is placed in the wedge-shaped area 15 and acts firstly to maintain the necessary insulation value to adjacent the outer surface 13A of the wall 13 and second:Ly acts as an insulating stop 7~7 thus preventing loose insulation from entering the soffit area. At the same time the desired air circulation is main-tained between the soffit area and the attic area 19.
Several embodiments are shown but they all incor-porate a substantially wedge-shaped block of insulating mate-rial having a relatively high R value. A preferred material to use is polyurethane but other rigid foam insulation mate-rials may be used depending upon design parameters and the desired R value required. It will also be appreciated that any other insulating material may be used instead of foam, depending once again on design parameters.
It consists of a substantially rectangular face 22 having a substantially rectangular wall 23 extending up-wardly therefrom. Spaced and para:Llel end walls 24 are pro-vided with another face 25 which curves over and then down-wardly towards a junction line 26 with the first mention-ed rectangular face 22. The configuration of the face 25 may curved inwardly as at 27 or may be relatively straight as at 28 (see Figure 1).
In the embodiment illustrated in Figures 1, 2 and 8, the insulating pillow is situated between adjacent ceiling joists 10, the width of the pillow being such that it is a relatively snug fit therebetween as clearly shown in Figure 1.
9~
Thus the rectangular face 22 becomes the base and it is moved outwardly towards the outer surface 13A of the wall until it takes up the position shown in Figures 1 and 8.
791~7 Depending upon the height of the rear side or thicker side of the wedge-shaped pillow, it may be neces-sary to provide an air vent slot 29 on the the upper side of the thicker end of the wedge and between the end walls 24, it being assumed that the device is in the position shown in Figures 1 and 8. It is also desirable to provide a rec-tangular panel 30 of screen material such as netting or the like secured by the lower edge thereof to adjacent the upper side of tne rectangular rear wall 23 as by stapling or ad-hesive. This flexible panel curves upwardly and inwardly when the pillow is installed as shown in Figure 8, and may be stapled or otherwise secured to the inner surface of the roof panel 16. This allows the desired air circulation to be maintained but prevents the loose insulation ~0 from passing outwardly into the soffit area. Once the pillGws are installed, the insulation may be blown or poured in position.
~ eans are provided to maintain the pillows in thedesired location and Figure 7 shows one embodiment compris-ing small tabs 31 extending outwardly from the pillow uponthe rectangular face 22 thereof. These may be stapled or otherwise secured to the ceiling joists 10 once it has been placed in position.
Alternatively, a plurality of small interference-fit protrusions 32 may be formed when the pillow is manufac-tured, extending from each end wall 24 so that when the 79t~
g pillow is engaged 'between the adjacent ceiling joists 10, these partially collapse and holds the pillow in position by friction.
Figures 3 through 6 show the device used in the preferred environrr,ent under which circurrlstances, it is re-versed with respect to Figures 1, 2, 7 and 8 and secured between adjacent roof joists 14. Once again the increase in thickness Detween the inner or relatively thin end 33 and the outer or thicker end 34, maintains the necessary ~ value to adjacent the outer surface 13A of the vertical wall.
The air vent slots are provided, in this embodiment, by the provision o~ a plurality o~ spaced apart protrusions 35 ex-tending from the rectangular face 22 and engaglng against the inner surface of the roof panel 16 thus permitting a flow of air to take place between the soffit area and the attic area above the insulation 20.
It may 'be held in position by means of the afore-mentioned tabs 31 or by the interference-fit protrusions 32 which engage against the inner surfaces of the adjacent roof rafters between wnich the pillow is situated.
A relatively small rectangular panel of screening rnaterial 36 rnay 'be secured to the thin end or junction 26 between the two faces and rnay extend upwardly to tne inner surface of the roof panel as shown in Figure 4 and may be secured thereto in order to prevent loose fill insulation from passing downwardly into the soffit area.
9f~7 _ 10 -One of the faults of loose or blown in insulation is that it tends to settle with time thereby developing an air gap illustrated by reference character 37 in Figures 3 and 6. In order to close this air gap, a strip of flexible material in the form of a flexible membrane 38 is secured across the thinner end 33 and hangs downwardly as clearly shown in Figure 5. When the insulat:ion is blown or other-wise installed, the membrane bends upwardly or flexes up-wardly as shown in Figure 6 and as the air gap 37 develops, this membrane maintains contact with the upper surface of the insulation. ILf this gap is not closed, the R values will not be additive between the insulation 20 and the pill.ow 21. As it settles, so will the floating membrane so that the developing air gap thus remains enclosed.
It will be appreciated that the insulating pillow 21 may, if desired, be surrounded with or by reflective foil which enhances the total R value considerably.
Figure 9 shows an alternative method of construc-ting the pillow which consists of foaming in place a pillow 21A within the area 18 and in the form of a wedge-shaped configuration similar to the pillow 21 except that the con-figuration is similar to that shown in Figure 10. It in-cludes the substantially rectangular face 22, the end walls 24, the substantially rectangular rear wall 23 and a rough 79~7 - lOA
surfaced upwardly and inwardly sloping face wall 38. A back stop panel 39 is first secured between the adjacent ceiling jolsts 10 and an inverted channel panel 39 is provided between adjacent ceiling joists portion 40 with side panels 41 which in turn are secured to the inner faces of adjacent ceiling joists 14 by staples 42 or the like. This channel is spaced downwardly rom the underside of the roof panel 16 andg when the foam is in place, provides the necessary air space between the pillow and roof panel, communicating with the soffit area.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made with the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illus-trative only and not in a limiting sense.
These ceiling joists rest upon the upper hori-~379!6~
zontal plate 12 of a vertical wall shown schematically at 13 and spaced and parallel roof rafters 14 also rest upon the plates 12 one adjacent each ceiling joist 10. Convention-ally, the roof rafters incline upwardly and inwardly from the upper side of the vertical wall 13 thus defining a wedge-shaped area 15 between adjacent joists 10, adjacent rafters 14, the ceiling panel 11 and a corresponding roof panel 16 spanning the upper sides of the roof rafters. The roof rafters normally extend outwardly beyond the outer side 13A
of the vertical wall with a soffit panel 17 extending in-wardly ~rom the extremities of the rafters to the outer sur-'7~ 6 face in a conventional manner. Such soffit areas or panels 17 normally include ventilators 18 at spaced intervals to permit air circulation through the attic area indicated by reference character 19.
In climates requiring the upper side of the ceil-ing panels 11 to be insulated, it is conventional to util-ize a standard loose fill insulation indicated by refer-ence character 20 and this insulation may take the form of fiber, loose rock, wool or the like. It is either poured or blown into position between adjacent joists 10 to a suffi-cient thickness above the joists to give the necessary insu-lating R value.
No problem is encountered in placing a sufficient thickness of insulation over the majority of the attic floor but as the wedge-shaped areas are encountered, it is obvious that the thickness of the insulation must decrease to prac-tically nil adjacent the outer surface 13A of the outer wall 13. This necessarily decreases the R value below the de-sired figure. Furthermore when such insulation is blown into position, it often extends between adjacent roof rafters and into the soffit area and may even 'Dlock the air intakes 18 thus preventing the desired circulation of air.
The pillow collectively designated 21 is placed in the wedge-shaped area 15 and acts firstly to maintain the necessary insulation value to adjacent the outer surface 13A of the wall 13 and second:Ly acts as an insulating stop 7~7 thus preventing loose insulation from entering the soffit area. At the same time the desired air circulation is main-tained between the soffit area and the attic area 19.
Several embodiments are shown but they all incor-porate a substantially wedge-shaped block of insulating mate-rial having a relatively high R value. A preferred material to use is polyurethane but other rigid foam insulation mate-rials may be used depending upon design parameters and the desired R value required. It will also be appreciated that any other insulating material may be used instead of foam, depending once again on design parameters.
It consists of a substantially rectangular face 22 having a substantially rectangular wall 23 extending up-wardly therefrom. Spaced and para:Llel end walls 24 are pro-vided with another face 25 which curves over and then down-wardly towards a junction line 26 with the first mention-ed rectangular face 22. The configuration of the face 25 may curved inwardly as at 27 or may be relatively straight as at 28 (see Figure 1).
In the embodiment illustrated in Figures 1, 2 and 8, the insulating pillow is situated between adjacent ceiling joists 10, the width of the pillow being such that it is a relatively snug fit therebetween as clearly shown in Figure 1.
9~
Thus the rectangular face 22 becomes the base and it is moved outwardly towards the outer surface 13A of the wall until it takes up the position shown in Figures 1 and 8.
791~7 Depending upon the height of the rear side or thicker side of the wedge-shaped pillow, it may be neces-sary to provide an air vent slot 29 on the the upper side of the thicker end of the wedge and between the end walls 24, it being assumed that the device is in the position shown in Figures 1 and 8. It is also desirable to provide a rec-tangular panel 30 of screen material such as netting or the like secured by the lower edge thereof to adjacent the upper side of tne rectangular rear wall 23 as by stapling or ad-hesive. This flexible panel curves upwardly and inwardly when the pillow is installed as shown in Figure 8, and may be stapled or otherwise secured to the inner surface of the roof panel 16. This allows the desired air circulation to be maintained but prevents the loose insulation ~0 from passing outwardly into the soffit area. Once the pillGws are installed, the insulation may be blown or poured in position.
~ eans are provided to maintain the pillows in thedesired location and Figure 7 shows one embodiment compris-ing small tabs 31 extending outwardly from the pillow uponthe rectangular face 22 thereof. These may be stapled or otherwise secured to the ceiling joists 10 once it has been placed in position.
Alternatively, a plurality of small interference-fit protrusions 32 may be formed when the pillow is manufac-tured, extending from each end wall 24 so that when the 79t~
g pillow is engaged 'between the adjacent ceiling joists 10, these partially collapse and holds the pillow in position by friction.
Figures 3 through 6 show the device used in the preferred environrr,ent under which circurrlstances, it is re-versed with respect to Figures 1, 2, 7 and 8 and secured between adjacent roof joists 14. Once again the increase in thickness Detween the inner or relatively thin end 33 and the outer or thicker end 34, maintains the necessary ~ value to adjacent the outer surface 13A of the vertical wall.
The air vent slots are provided, in this embodiment, by the provision o~ a plurality o~ spaced apart protrusions 35 ex-tending from the rectangular face 22 and engaglng against the inner surface of the roof panel 16 thus permitting a flow of air to take place between the soffit area and the attic area above the insulation 20.
It may 'be held in position by means of the afore-mentioned tabs 31 or by the interference-fit protrusions 32 which engage against the inner surfaces of the adjacent roof rafters between wnich the pillow is situated.
A relatively small rectangular panel of screening rnaterial 36 rnay 'be secured to the thin end or junction 26 between the two faces and rnay extend upwardly to tne inner surface of the roof panel as shown in Figure 4 and may be secured thereto in order to prevent loose fill insulation from passing downwardly into the soffit area.
9f~7 _ 10 -One of the faults of loose or blown in insulation is that it tends to settle with time thereby developing an air gap illustrated by reference character 37 in Figures 3 and 6. In order to close this air gap, a strip of flexible material in the form of a flexible membrane 38 is secured across the thinner end 33 and hangs downwardly as clearly shown in Figure 5. When the insulat:ion is blown or other-wise installed, the membrane bends upwardly or flexes up-wardly as shown in Figure 6 and as the air gap 37 develops, this membrane maintains contact with the upper surface of the insulation. ILf this gap is not closed, the R values will not be additive between the insulation 20 and the pill.ow 21. As it settles, so will the floating membrane so that the developing air gap thus remains enclosed.
It will be appreciated that the insulating pillow 21 may, if desired, be surrounded with or by reflective foil which enhances the total R value considerably.
Figure 9 shows an alternative method of construc-ting the pillow which consists of foaming in place a pillow 21A within the area 18 and in the form of a wedge-shaped configuration similar to the pillow 21 except that the con-figuration is similar to that shown in Figure 10. It in-cludes the substantially rectangular face 22, the end walls 24, the substantially rectangular rear wall 23 and a rough 79~7 - lOA
surfaced upwardly and inwardly sloping face wall 38. A back stop panel 39 is first secured between the adjacent ceiling jolsts 10 and an inverted channel panel 39 is provided between adjacent ceiling joists portion 40 with side panels 41 which in turn are secured to the inner faces of adjacent ceiling joists 14 by staples 42 or the like. This channel is spaced downwardly rom the underside of the roof panel 16 andg when the foam is in place, provides the necessary air space between the pillow and roof panel, communicating with the soffit area.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made with the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illus-trative only and not in a limiting sense.
Claims
CLAIMS:
(1) A wall line insulation pillow locatable within the wedge-shaped recess defined by adjacent roof rafters, roof panels extending therebetween and adjacent ceiling joists and ceiling panels therebetween, said pillow maintaining the insulation R value between attic insulation and the outer surface of the structural wall; comprising in combination a substantially wedge-shaped block of insul-ating material having a first planar substantially rec-tangular face, a substantially rectangular wall extending upwardly from one edge of said face, spaced and parallel side walls extending upwardly from said face and a second face extending from the distal edge of said wall to the other edge of said second face with the thickness and hence the R value of said pillow increasing from said other edge of said face towards said substantially rec-tangular wall, said pillow, when in situ, being situated with said first face forming the base thereof and engaging said ceiling panels between adjacent ceiling joists and air vent means being formed through said second face from the front to the rear thereof, said rectangular wall join-ing contiguously with said first planar face at a corner whereby said pillow can be slid into place in said wedge shape recess with said first face in contact with said ceiling panel until said second face engages said roof panel.
(2) The pillow according to Claim 1 which in-cludes air vent means formed along one of said faces.
(3) The pillow according to Claim 1 in which said pillow, when in situ, is situated with said one face forming the upper side thereof and engaging between adja-cent the associated roof panel, an air vent means being formed through said one face.
(4) The pillow according to Claim 2 which in-cludes air vent means formed along one of said faces.
(5) The pillow according to Claim 1 which in-cludes means to maintain said pillow in position, said means including collapsible interference fit protrusions extending from each side wall of said pillow.
(6) The pillow according to Claim 1, 2 or 3 which includes a flexible screen panel secured by one edge thereof to adjacent the upper rear edge of said rectangular wall and securable to the associated roof panel.
(7) The pillow according to Claim 6 which includes a flexible membrane secured by one edge thereof to the junction between said faces and depending downwardly therefrom when said pillow is in situ between adjacent roof rafters.
(8) The pillow according to Claim 1, 2 or 3 in which said pillow is covered by reflective material.
(1) A wall line insulation pillow locatable within the wedge-shaped recess defined by adjacent roof rafters, roof panels extending therebetween and adjacent ceiling joists and ceiling panels therebetween, said pillow maintaining the insulation R value between attic insulation and the outer surface of the structural wall; comprising in combination a substantially wedge-shaped block of insul-ating material having a first planar substantially rec-tangular face, a substantially rectangular wall extending upwardly from one edge of said face, spaced and parallel side walls extending upwardly from said face and a second face extending from the distal edge of said wall to the other edge of said second face with the thickness and hence the R value of said pillow increasing from said other edge of said face towards said substantially rec-tangular wall, said pillow, when in situ, being situated with said first face forming the base thereof and engaging said ceiling panels between adjacent ceiling joists and air vent means being formed through said second face from the front to the rear thereof, said rectangular wall join-ing contiguously with said first planar face at a corner whereby said pillow can be slid into place in said wedge shape recess with said first face in contact with said ceiling panel until said second face engages said roof panel.
(2) The pillow according to Claim 1 which in-cludes air vent means formed along one of said faces.
(3) The pillow according to Claim 1 in which said pillow, when in situ, is situated with said one face forming the upper side thereof and engaging between adja-cent the associated roof panel, an air vent means being formed through said one face.
(4) The pillow according to Claim 2 which in-cludes air vent means formed along one of said faces.
(5) The pillow according to Claim 1 which in-cludes means to maintain said pillow in position, said means including collapsible interference fit protrusions extending from each side wall of said pillow.
(6) The pillow according to Claim 1, 2 or 3 which includes a flexible screen panel secured by one edge thereof to adjacent the upper rear edge of said rectangular wall and securable to the associated roof panel.
(7) The pillow according to Claim 6 which includes a flexible membrane secured by one edge thereof to the junction between said faces and depending downwardly therefrom when said pillow is in situ between adjacent roof rafters.
(8) The pillow according to Claim 1, 2 or 3 in which said pillow is covered by reflective material.
