Abstract
ABSTRACT OF THE DISCLOSURE:
A width adjustable, two face, expanded polystyrene panel includes a plurality of parallel, spaced-apart first slots open to a first panel face and a plurality of parallel, spaced-apart second slots parallel to said first slots and open to a second opposite panel face. Each of the second slots is situated in a plane equidistant from the planes of two adjacent first slots. The first and second slots overlap each other substantially. That is, each of the slots extends well past a plane parallel to the first and second panel faces and situated midway between those two faces.

Description
9 2 ~ 2 WIDTH ADJUSTABLE EXPAN~ED FOAM INSULATION PANELS
BACKGROUND OF THE INVENTION:
This invention has relation to the insulating of buildir.g walls and particularly to the applying of insula-tion to fill the void between adjacent vertical wall studs and between the outer wall sheathing and the interior wall paneling. In the past, such voids have been filled with a large number of insulating materials including shredded newspapers, rocks, and about every imaginable substance.
However, common in new building construction today is the use of fiberglass batts which have an R value of 3 or rock wool batts having an R value of about 3.25.
Expanded polystyrene foam panels would make an excellent insulating material at such locations, the R value being 4.35. Also, such panels present no moisture problem such as that presented by fiberglass and rock wool batts, for example.
The difficulty with the use of such expanded poly-styrene panels, before the present invention, was that, in order to get an effective fit and seal of the panel between the wall studs, each panel would have to be made oversize and then trimmed to take into account the irregulariti.es in the particular two by fours constituting the wall skuds defining a certain void to be filled and to take into account the irregulari~ies in the size of the void caused by the fact that these wall studs are seldom positioned in exact parallel relationship with respect to each other. This extra fitting and cutting and handling has made it economically impossible to employ such panels. Further, it is virtually impossible, even with such a fitting, to get a good seal against both of 19 ~
~ ~9~2 the wall studs. Any tendency for the panel to shrink over its lifetime will further destroy the seal and therefore a lot of the insulating value of the panel.
It is well known to fill the voids between wall studs and the sheathing and interior wall panels in houses after such walls have been constructed by blowing dry insula-tin~ material into such spaces from holes in the shea~hing at the top of the void after the walls have been constructed.
However, such dry materials will settle over their lifetime, and this settling leaves progressively larger areas at the top of each such void where no insulating material is present~
Such voids have also been filled and are being filled with active and expanding foam materials. However, when this foam sets up, there is a certain amount of inherent shrinkage which pulls the foam mass away from the wall studs and all sides of the insulated void thus very substantially decreasing the insulating value of such foam.
In order to provide insulating panels which will --~ompletely fill voids between adjacent approximately parallel wall studs/ and which will continue to substantially completely fill such voids over the life of the building wall, the width adjustable expanded foam insulating panels of the present invention were developed.
No search has been made in regard to this invention.
However, ~he inventor and those in privity with him know of no prior art which anticipates the claims made in this appli-cation.
BRIEF SU~MARY OF THE INVENTION:
Width adjustable expanded foam insulating panels are made from ~lat sheets of low density, firm, resilient, ~ ~69~2 insulating material having a uniform nominal thickness through-out. They can be installed against building wall sheathing or other walls to abut against spaced-apart pairs of wall studs or other abutments where the spacing between such abutment pairs is not uniform. The nominal widths of these panels from side edge to side edge will be the same as or, preferably, slightly greater than the maximum dimension between adjacent wall studs or other abutments.
The invention provides a laterally compressible insulating panel of rigid foamed plastic adapted to be fitted into an open space between a pair of spaced-apart approximately parallel stud-like abutments extending outwardly from a wall;

By providing many first and second slots, a consider-able width variation can be obtained in a panel to make it possible to install that panel between pairs of wall studs or other abutments which vary widely in spacing. However, where such panels are to be used between pairs of wall studs which do not vary substantially in spacing, as little as a single :
slot open to one face and another single slot open to the other face can give the necessary adjustability in accordance with the teaching of the invention.

DESCRIPTION OF PREFERRED EMBODIM~NT:
A width adjustable expanded cellular insulating panel 10 can be made of expanded polystyrene foam or any other suitable product having thermal insulation and/or sound daadening characteristics. This can include foamed or expanded urethanes, for example. The invention is not li~lited to any particular panel structure, except one that can be deformed slightly upon receiving edge to edge compression in a manner to be described.
Each such insulation panel 10 is designed to be installed against a flat surface such as building wall 1 ~92~2 sheathing 12 and to fit snugly between two outstanding abutments such as building wall studs 1~. In order to be of maximum value as an insulating panel, it is important that side edges 16 and 18 of the insulation panels 10 fit snugly if not tightly against the building wall studs 14. I it were possible to utilize only exactly parallel and perfect wall studs 14, and if these wall studs were always placed on the same center dimension, for example, 16 inches on center, then it would be possible to manufacture each insul ation panel to have precisely the proper width to he gently forced into place between the wall studs to form a perfect seal and to provide maximum insulation value~ However, wall studs are not perfectly straight, are not of uniform exact thickness, are not installed perfectly at right angles to the top plate and floor plate~ Further, in the design and construction of buildings~ it is not possible or even desirable to maintain every vertical wall stud in a 16 inch center-to-center relationship with respect to its adjacent wall stud. It is to accommodate variations in the spacing between any two particular wall studs from top to bottom thereof and to accommodate different center line spacings between wall studs that the insulation panel of the present invention was developed.
In order to provide for such adjustment, each insulation panel 10 is provided with a series of parallel, spaced-apart, first slots 20 open to a first face 22 thereof;
and a plurality of parallel, spaced-apart/ second slots 24 open to a second face 26 of the insulation panel 10. The second slots 24 extend part way through the panel to be in spaced relation between the first slots 20, and in the form of invention shown, neither sets of slots extends toward the g 2 ~ 2 opposite face any closer than the width between adjacentfirst and second slots. The full thickness insulation panel portion between adjacent slots 20 and 24 are designated as insulation panel bars 27 each having a width indicated at 28 in FIG. 4.
As best seen in FIGS. 2 and 4, the insulation panel 10 need be compressed laterally only very slightl~ in order to take its position between the wall studs 14 and to be snugly in contact with them to provide insulation from one surface of one of the studs to the other surface of the other stud.
As seen in FIG. 3, when the facing between the wall studs 14 is less than the nominal spacing shown in FIG. 2, the insulation panel 10 can be laterally compressed to change its dimension sufficiently so that it can be placed between the wall studs 14l14 and allowed to ex~and resiliently back into very firm contact with those wall studs.
As seen in FIG. 5, if the spa~ing between the wall studs i5 such that compression of the insulation panel completely does not make it possible to fit the panel between the adjacent wall studs 14, one or more of the full width insulation panel bars 27 adjacent one of the slots 20 or 24 can be broken or cut off by making a cut through the insulation panel extending from the bottom of that slot to the opposite face of the panel. The insulation panel can then be compressed laterally, and it will fit between the building wall studs 14,14 as seen in FIG. 5. For example, an outermost full width insulation panel bar 30 as seen in FIG. 3 can be removed from its adjacent insulation panel har 32 by making a break or cut along the dotted line 34. This same insulation panel 10 can then be further compressed and placed between building --6~
2 ~ 2 wall studs 14,14 which are much closer to each other, to take the position as seen in FIG. 5.
By providing many first and second slots, a consider-able width variation can be obtained in a panel to make it possible to install that panel between pairs of wall studs or other abutments which vary widely in spacing. However, where such panels are to be used between pairs of wall studs which do not vary substantially in spacing, as little as a single :
slot open to one face and another single slot open to the other face can give the necessary adjustability in accordance with the teaching of the invention.

The insulation panel can then be compressed laterally, and it will fit between the building wall studs 14,14 as seen in FIG. 5.
