DETAILED DESCRIPTION OF THE INVENTION

[0022] Aside from the preferred embodiment or embodiments disclosed below, this invention is capable of other embodiments and of being practiced or being carried out in various ways. Thus, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. If only one embodiment is described herein, the claims hereof are not to be limited to that embodiment. Moreover, the claims hereof are not to be read restrictively unless there is clear and convincing evidence manifesting a certain exclusion, restriction, or disclaimer.

[0023] In one example, the building insulation and cladding system includes a plurality of spaced vertically extending tracks 10 (for example a Z-girt shaped track). Securable to the building exterior which may include building wall 12 with existing sheathing 14 covered with a vapor permeable membrane 16 (e.g., an adaptive weather resistant barrier (AWRB)) and/or additional insulation and/or other waterproof layers. Tracks 10 can be secured to the building exterior using fasteners. Tracks 10 can be assembled together as a subframe including L-angle top member 18 and a similar bottom L-angle member (not shown in FIG. 1) and the subframe then fastened to the building exterior. Other subframe combinations are possible.

[0024] Then, clips 20 (e.g. made of plastic) are fitted to the tracks. Preferably, each clip 20 includes a top rail 22 which is received in a lower edge groove 24 of a building structure 26 to support the building structure on top of a row of clips.

[0025] Also, the clips preferably include means such as a lower gripping surface with teeth 27 (FIG. 3) 28 configured to allow the top edge 32 of a lower building structure 26 in FIG. 1 to snap fit underneath clip 20 and is thus held in place by teeth 27 at least while the next building structure in FIG. 1 is installed on the top of the spaced clips. Thereafter, outer lower edge 30 of each building structure in FIG. 1 prevents the top edge 32 of the lower building structure in FIG. 1 from pivoting outwardly.

[0026] The building structures can be in the form of panels as shown in FIG. 1 and/or configured around windows, doors, and the like as shown in FIG. 2. The building structures may include an insulation core 40, FIG. 1 and outer coating 42. The building structures may also include other insulation components 50, FIG. 2 pre-configured as a set for a given building layout. In one example, the building structures include a wood fiber or hemp wool insulation core. Coating 42 may be an epoxy.

[0027] As shown in FIG. 3, additional insulation and/or protective layers can be used in the system such as mineral wool insulation 50 behind building structure panels 26. Breather and/or water-resistant layers can also be used.

[0028] FIG. 3 also shows how clip 20 includes spaced rearwardly extending upper tab 60a and lower tab 60b which are received in spaced slots 62a, 62b in track 10. Tab 60b may include a spring finger 64b as shown which flexes into slot 62b and springs upward so barb 65 catches the track 10. Tab 60a includes upwards extension 61 held against the back side of track 10.

[0029] In one preferred version as shown in FIG. 3, each building structure 26 includes a top edge profile with first (70a) and second (70b) ascending steps and a bottom edge profile with outer lower edge 72 to be seated on or near the tread of first step 70a of the lower building structure. Preferably, the tread of step 70b engages the underside of the clip allowing the top edge of each building structure to snap fit underneath a set of clips. In some versions, the tread of step 70a of the lowermost building structure 26 in FIG. 3 supports outer lower edge 72 of the next upper adjacent building structure 26 in FIG. 3. In other versions, there is a space between step 70a and outer lower edge 72 which can be sealed by a gasket if desired.

[0030] Also, preferably, each clip 20 further includes top shelf 78 inward of rail 22 and each building structure 26 includes inner lower edge 80 which may seat on clip shelf 78. In other examples, the building structure is supported only by the clip rail.

[0031] FIG. 3 also shows how clip rail 22 seats in panel 26 lower edge groove 24.

[0032] FIG. 4A depicts the structure of a long panel clip 20 while FIG. 4B shows a typical short version and FIG. 4C shows a panel clip that also joins two adjacent vertical tracks.

[0033] In FIGS. 5A-5F, vertical track 10 is fastened to L-angle member 18 in order to assemble a subframe joint.

[0034] In FIG. 6A-6D, a clip is shown being inserted and mated with a vertical track.

[0035] FIG. 7A shows a method of assembly and hanging of a subframe on a mockup of an existing building structure with numerous vertical tracks 10 and upper and lower subframe members connected between the spaced vertically extending Z-shaped side tracks. Successive rows of clips are then installed as shown in FIG. 7B and the building structure panels 26 are then dropped into place starting with the lowermost building structure panels seated on the lowermost row of clips and snap fit underneath the next uppermost row of clips. FIGS. 7D-7F depict additional panels being inserted and attached to the clips and to the building exterior. Thus, as can be seen the plurality of clips are configured to join two adjacent building structures and to secure the building structures to the tracks and this to the building exterior. The clips preferably include a top surface profile complementary to the building structure lower edge profile to support a building structure on the clip and the clips have a bottom surface profile complementary to the building structure upper edge profile to snap fit a building structure under the clip. Although specific features of the invention are shown in some drawings and not in others, this is for convenience only as each feature may be combined with any or all of the other features in accordance with the invention. The words including, comprising, having, and with as used herein are to be interpreted broadly and comprehensively and are not limited to any physical interconnection. Moreover, any embodiments disclosed in the subject application are not to be taken as the only possible embodiments. Other embodiments will occur to those skilled in the art and are within the following claims.

[0036] In addition, any amendment presented during the prosecution of the patent application for this patent is not a disclaimer of any claim element presented in the application as filed: those skilled in the art cannot reasonably be expected to draft a claim that would literally encompass all possible equivalents, many equivalents will be unforeseeable at the time of the amendment and are beyond a fair interpretation of what is to be surrendered (if anything), the rationale underlying the amendment may bear no more than a tangential relation to many equivalents, and/or there are many other reasons the applicant cannot be expected to describe certain insubstantial substitutes for any claim element amended.
