Thermasheath®-3 insulation boards, when covered by an approved 15-minute thermal barrier, may be used within or on interior walls, roof assemblies, floor assemblies, ceiling assemblies and wall cavities in any construction type. The insulation boards can be used at the perimeter or under flat concrete slab on grade construction, or on the exterior or interior of basement foundation walls in any construction type. They also can be used on the outside faces of exterior walls of Type V-B (IBC) construction or dwellings under the IRC. Thermasheath®-3 insulation boards may be used in attics and crawl spaces without a 15-minute thermal barrier or an ignition barrier required by the code, when installed in accordance with Section 4.2.1. 2.2 TSX-8500 and TSX-8510: Rmax® TSX-8500 and TSX-8510 insulation boards are used as nonstructural, thermal insulating materials in Types I, II, III, IV and V construction (IBC) and dwellings under the IRC. The insulation boards may be used without a thermal barrier within or on interior walls, the inside face of exterior walls, roof assemblies, floor assemblies, ceiling assemblies and wall cavities in any construction type. The insulation boards may also be used at the perimeter or under flat concrete slab on grade construction and on the exterior or interior of basement foundation walls in any construction type. They also may be used on the outside faces of exterior walls of any type construction or dwellings under the IRC. When used in exterior walls in Types I, II, III and IV construction, construction must be in accordance with Section 4.4. TSX-8500 and TSX-8510 insulation boards may be used in attics and crawl spaces without a 15-minute thermal barrier or an ignition barrier required by the code, when installed in accordance with Section 4.3.2. 3.0 DESCRIPTION 3.1 Materials: 3.1.1 General: Rmax® insulation boards are nonstructural, closed-cell, rigid polyisocyanurate, foam plastic insulation boards that are faced on both sides. The foam plastic core has a nominal density of 2 pcf (32 kg/m3). The boards are available in various lengths and widths. 3.1.2 Thermasheath®-3: Thermasheath®-3 insulation boards consist of a polyisocyanurate foam core described in Section 3.1.1, faced on both sides with aluminum foil bonded to kraft paper. The boards have square edges and are available in thicknesses of 1/2 inch to 41/2 inches (12.7 mm to 114 mm). Thermasheath®-3 insulation boards are Type I, Class 1, materials in accordance with ASTM C1289. 3.1.3 TSX-8500: TSX-8500 insulation boards consist of the polyisocyanurate foam core described in Section 3.1.1, with a silver facer consisting of aluminum-foil bonded to *Revised March 2015 ESR-1864 | Most Widely Accepted and Trusted Page 2 of 4 glass-fiber mat on one side. The other side is faced with either aluminum-foil bonded to glass-fiber mat or a sheet consisting of aluminum foil bonded to kraft paper. The boards have square edges and are available in thicknesses of 1/2-inch to 41/2 inches (12.7 mm to 114 mm). TSX-8500 insulation boards are Type I, Class 1, materials in accordance with ASTM C1289. 3.1.4 TSX-8510: TSX-8510 is the same as TSX-8500 except that the silver facer is replaced with a white facer made of the same material. 3.2 Surface-burning characteristics: The Thermasheath®-3 insulation boards have a flame- spread index of 75 or less and a smoke-developed index of 450 or less at a maximum thickness of 41/2 inches (114 mm), when tested in accordance with ASTM E84. The TSX-8500 and TSX-8510 insulation boards have a flame-spread index of 25 or less and a smoke-developed index of 450 or less at a maximum thickness of 41/2 inches (114 mm), when tested in accordance with ASTM E84. 3.3 Thermal Resistance: The insulation boards have thermal resistances, R-values, at a mean temperature of 75°F (24°C), as shown in Table 1. 3.4 Vapor Permeability: At a minimum thickness of 1/2 inch (12.7 mm), the insulation boards have vapor permeance of less than 0.1 perm [5.7x1012 kg/(Pa-s-m2)] when tested in accordance with ASTM E96 (desiccant method) (Procedure A), and qualify as a Class I vapor retarder. 4.0 INSTALLATION 4.1 General: The insulation boards must be installed in accordance with the Rmax® published installation instructions, the applicable code and this report. The manufacturer’s published installation instructions must be available on the jobsite at all times during installation. The insulating boards may be installed on any or all surfaces up to a thickness of 12 inches (305 mm) based on room corner fire testing in accordance with UL 1715, when covered with a minimum ½-inch-thick (12.7 mm) gypsum board complying with the applicable code. Exceptions to the requirement of a thermal or ignition barrier covering are detailed in Section 4.2.1 for Thermasheath-3 or Sections 4.3.1 and 4.3.2 for TSX-8500 and TSX-8510. The insulation boards may be installed in either single or multiple layers up to the maximum thickness. When installed against wood or steel framing, the fasteners must be of sufficient length to penetrate into wood framing a minimum of 3/4 inch (19 mm) or through the steel framing a minimum 29/64 inch (11.4 mm). For cementitious exterior wall coating applications, fasteners for insulations boards thicker than 11/2 inches (38 mm) must take into account for lateral resistance to provide support for the exterior wall coatings. Exterior wall assemblies, exterior finishes or wall covering assemblies must be structurally adequate to resist transverse loads. All walls must be braced in accordance with IBC Sections 2308.9.3 and 2308.12.4 or IRC Section R602.10.3, as applicable. 4.2 Thermasheath®-3 — Installation without a Prescriptive Ignition Barrier: 4.2.1 Attics and Crawl Spaces: Thermasheath®-3 insulation boards, at a maximum thickness of 1 inch (25.4 mm), may be used on walls of attics or crawl spaces with no covering applied to the attic or crawl space side of the foam plastic when installation is in accordance with all of the following conditions: a. Entry to attic or crawl space is only to service utilities, and no storage is permitted. b. There are no interconnecting attic or crawl space areas. c. Air in the attic or crawl space is not circulated to other parts of the building. d.
