Thermasheath-XP. Insulation for Exposed Use

Transcription

1 Insulation for Exposed Use PRODUCT DESCRIPTION Rmax Thermasheath-XP is an energy-efficient thermal insulation board composed of a closed-cell polyisocyanurate (Polyiso) foam bonded to durable, embossed aluminum facers on both sides. One side has a white modified acrylic coating, and the other side has a reflective surface with a clear coating. The foam core utilizes a CFC, HCFC and HFC free blowing agent that has zero Ozone Depletion Potential (ODP) and negligible Global Warming Potential (GWP). This pressure washable insulation is suitable for use in wall or ceiling applications in residential buildings new construction or thermal retrofit. Specifically, Thermasheath-XP is ideal for masonry or stud construction; attics and crawls spaces; sheds and other light storage structures. Thermasheath-XP is designed for use without a thermal barrier to provide an attractive interior finish. Thermasheath-XP is just one of the many Rmax products providing a one-stop shop for all your residential insulation needs. Rmax s engineered products and solutions allow for optimal energy efficiency and ease of construction, all while adding to the bottom line through both material and labor savings.

APPLICATION / INSTALLATION General Thermasheath-XP passes UL75 (walls only or ceilings only) without joint treatment of any kind. Therefore, the boards only need to be tightly butted. However, taping the seams is acceptable. Rmax recommends using R-SEAL 3000 or equivalent for the reflective silver side, and R-SEAL 3000W or equivalent for the white side. Thermasheath-XP may be covered with an interior finish product provided it is compliant with the requirements of IBC Chapter 8. A quality grade acrylic latex paint is recommended for coating the surface. While primer is not generally required, consult the paint manufacturer and/or industrial paint supply for recommendations and best practices. Radiant Barrier The reflective side of Thermasheath-XP acts as a radiant barrier; adding to the energy efficiency of the assembly. To achieve radiant barrier properties, the silver surface must face an air space. For optimal performance, install perpendicular to the radiant heat flow and in a manner to minimize dust accumulation. The ASHRAE Handbook of Fundamentals, assigns values to air-tight spaces under varying conditions. For example, ASHRAE assigns a 2.77 R-value to a 3/4 inch air-tight space against a reflective foil in a typical wall assembly such as when Thermasheath-XP is installed over furring strips against a block wall. This value is in addition to the R-value of the polyiso foam. Pressure Washable Thermasheath-XP is pressure washable, up to 000 psi using a spray rig. The wand nozzle must have a fan spray tip with an angle of at least 5 degrees. The washing wand should not be used at a distance of less than 3 feet from the surface of the insulation board. Pressures greater than 000 psi may result in damage to the insulation facer. Masonry Thermasheath-XP may be applied to the interior face of concrete or concrete masonry walls to provide a finished layer of continuous insulation (ci) over the entire surface. For example, Thermasheath-XP is an excellent product for use in insulating the interior side of basement walls. It may be adhered or anchored directly to the concrete surface or attached to furring. Use Rmax PVC insulation clips for an easy, yet clean, professional install. Refer to Rmax publication, Installation Instructions for Exposed Basement Walls, for additional information and guidelines on installation, joint treatment and sealing techniques. Stud Wall Construction Thermasheath-XP may be applied to the interior face of wood studs for additional thermal protection with a finished appearance. For example, Thermasheath-XP is an excellent product for use in insulating walls or ceilings of garages. Simply fasten the Thermasheath-XP directly to the wood framing. Securement Thermasheath-XP may be fastened to wood framing using roofing nails, bugle head screws or minimum 3/4 inch cap nails. The fasteners shall be long enough to penetrate at least inch into the wood framing. Thermasheath-XP may be fastened to metal framing using self-taping screws and plastic washers. The fasteners shall be long enough to penetrate at least 4 threads into the metal framing. Wherever possible, the insulation boards shall be installed vertically with all edges tightly butted and backed by framing. Thermasheath-XP may be secured to concrete surfaces using plastic masonry fasteners with washers or a quality grade construction adhesive.

3 Attics Thermasheath-XP may be applied to the interior face of stud walls or roof rafters within attics without the need for an additional thermal or ignition barrier, including when the space is used for storage. Simply fasten the Thermasheath-XP directly to the wood framing. Consult your local Building Code for ventilation requirements within attics. Sheds and Other Light Storage Structures Thermasheath-XP may be used as an exposed, finished, continuous insulation (ci) system in sheds and other light storage structures. It may be secured directly to the wood or metal framing. Crawl Spaces Thermasheath-XP may be applied to the walls or ceilings within crawl spaces without the need for an additional thermal or ignition barrier, including when the space is used for storage. Simply fasten the Thermasheath-XP directly to the masonry or wood framing. Consult your local Building Code for ventilation requirements within crawl spaces. LIMITATIONS Thermasheath-XP is not recommended, nor warranted, for use as a commercial roof insulation directly under membrane systems. Consult Rmax Sales for suitable commercial roof insulation products. Thermasheath-XP is not a structural panel. It must not be used as a nailing base for any other building products. Furthermore, walls insulated with Thermasheath-XP must be properly braced for lateral loads according to the requirements of local Building Codes. WARNING Polyiso foam is an organic material which will burn when exposed to an ignition source of sufficient heat and intensity and may contribute to flames spreading. Consult local Building Codes and insurance authorities regarding special applications or details required when using Thermasheath-XP as an exposed product. The code also has provisions regarding vapor retarders, type and location, based on the assembly, climate zone and the amount of continuous insulation. It is up to the design professional to specify an assembly that will perform adequately and meet these requirements. Use care when handling insulation. Product may have sharp edges and could result in injury. To avoid, use protective puncture-resistant gloves and/or sleeves when handling.

Rmax does not assume any responsibility or liability for the performance of any products other than those manufactured by Rmax. NOTE: All Rmax products must be tarped, placed on skids and kept dry before and throughout construction.
