These include the panel 300, the insulating panel 310, the water-resistant interior facing 320, the exterior air and rain-barrier facing 330, the female rabbet edge 340, the male rabbet edge 350, the skirt 360 and the tape or adhesive 370. elements will not be described again.
• the panel 300 further comprises an improved fire-resistant "face” 380, possibly provided on the side of the insulator 310 which is facing the interior of the building.
• the fire resistance is provided by a coating or cladding 380 applied to the insulation 310, over the inner cladding 320.
• the improved fire-resistant coating is applied directly to the insulation 310, without any 320 facing layer.
• a mixture comprising vermiculite and expandable graphite is dispersed in water, and the dispersion is coated on the glass fiber substrate 310, and dried.
• This process is described in detail in U.S. Patent Application Serial No. 10 / 322,433, filed December 19, 2002, incorporated herein by reference.
• Some particular examples of fire resistant facing materials 380 that can be used to improve fire resistance include:
• the surface of the panel 100 or 300 closest to the installer is the surface of the panel 100 or 300 closest to the installer
• the outer layer 130 is provided with vertical lines 400 printed every inch (or at another chosen interval) to serve as guide marks for the installation of the panel 100 or 300 on the steel uprights 202.
• All Screws (or other fasteners) 402 driven through panel 100 or 300 must penetrate into a steel stud 202 under the panel.
• Most of the steel stud 202 is concealed by panel 100, 300 (as shown in FIG. 4) when the installer places the panel against the studs. However, the top of the amount 202 is visible, and the installer can identify the position of the steel uprights 202 relative to the pattern of vertical lines printed on the face of the panel.
• the installer can place his fastening screws 402 at these vertical lines 400 in the middle, at the top and bottom of the panel 100, 300.
• the panels serve as spacing mark.
• This mark indicates the fastener separation position required by the manufacturer or architect (for example, 12 inches center-to-center, or every 12 inches). This will facilitate also the installation process, as long as the installer can count the lines once, start the installation and follow the same line throughout the installation.
• these lines may be of different but repeating colors (e.g., 6 or 12 different colors that repeat in the same manner). This would provide the installer with a line that is easy to identify and follow for the installation process (that is, if the installer starts on the red line, he knows he has to follow the red line for the rest of this line fastenings).
• FIG. 5 illustrates another example in which vertical lines 400 and horizontal lines 502 are provided to form a grid pattern. Regardless of the orientation of the panel, one group of lines will be parallel to the uprights 202, and the other group of lines may be used to space the anchors (or other fasteners).
• FIG. 6 illustrates another external wall 600, namely a variant of the wall 200 of FIG. 2. The similar elements are identified by similar numerical references. The elements described above with reference to Figure 2 will not be mentioned again.
• the wall 600 includes steel posts 202, an outer gypsum layer 602 held in place by fasteners 604, a panel 100, anchors (or other fasteners 208) to the wall, and an exterior stone veneer (or other outer layer of building) 204.
• the inner facing 120 of Figure 6 may optionally be a variable type vapor retarder 120 (such as the Smart MEMBRAIN TM vapor retarder marketed by Valley Forge's CertainTeed Corp.). in Pennsylvania).
• a variable type vapor retarder 120 such as the Smart MEMBRAIN TM vapor retarder marketed by Valley Forge's CertainTeed Corp.). in Pennsylvania.
• the fasteners 206 are not necessary, since the panel system 110 includes an attachment to the outer wall 204, e.g. tie rods for brick.
• FIG. 8 is a cross-sectional view of a wall 800, namely another variant of the wall of FIG. 2. In FIG.
• an air gap is provided between the panel 100 and the outer building layer 204.
• the outer building layer 204 may be "freestanding" in the vertical direction (eg, brick) and may possibly require only anchors 806 in the horizontal direction for tensile and compressive strength.
• the anchor 806 may be an "X-Seal TM" anchor marketed by Hohmann and Barnard, Inc. of Hauppauge, New York.
• the anchor device "X-Seal TM" is advantageously used for the insulating panel 110 in that it transfers the load of the outer wall to the steel upright 202.
