Non-Wood SIPs | 2.2Fiber-Reinforced Plastic Panels:Fiber-reinforced plastic (FRP) is a composite material madeof a polymer reinforced by fiberglass or other fibers. FRPis typically used in combination with a polyurethane core.The manufacturing process uses synthetic compositematerials and industrial processes similar to those of themarine and aircraft construction industries. This type ofconstruction is most common in coastal areas.Non-Wood SIPsOverview: Structural insulated panels can be manufacturedusing a variety of non-wood structural skin materials.These include metal (stainless or galvanized steel),fiber-reinforced cement, and fiber-reinforced plastic (FRP).Like wood SIPs, these panels are used to build floors, exteriorwalls, and roofs, and may be used alone or as part of ahybrid system that also uses steel framing, wood framing,concrete, or other building techniques.Metal Panels:Stainless Steel (SS) and G90 Galvanized are the most commonlyused metal surfaces. Metal panels can be used forresidences or residential roofs, but are more often used inindustrial or commercial buildings that require the product’sstrength or non-corrosive properties. Stainless steelis essentially low carbon steel containing 10% or morechromium, which gives the steel its corrosion-resistingproperties. Galvanized steel is coated with a thin layer ofzinc that protects the steel from corrosion. Metal SIPs canbe costly, but for the right application, the benefits maybe worth the extra cost. Benefits include: corrosion-resistance,fire- and heat-resistance, hygiene, noise insulation,good strength-to-weight ratio; and impact resistance.Fiber Cement Panels:Fiber-reinforced cement (‘fiber cement’) is a mixture of cement,sand, cellulose fibers, silica, and additives, which areautoclaved (cured with pressurized steam) and moldedinto finished siding products. Fiber cement products suchas those manufactured by the James Hardie Corporationare commonly used for siding, trim, and other exteriorand interior applications. Panels can be made with fibercement on one or both sides as a finished or unfinishedsurface. According to ToolBase, a technical homebuildinginformation, “manufacturers emphasize that fiber-cementsiding is appropriate for hot and humid climates becauseit is resistant to rot, fungus, and termite infestation. Theyalso state that it has excellent weathering characteristics,strength, and impact resistance.” 6INSTALLATION<strong>Construction</strong> Process: Methods of constructionvary depending on the manufacturer and system in use.In most cases, panels are mechanically connected usingpower-driven screws or cam-locks. In other cases, connectionsare made using glue, resin, and/or specialized tools.Most non-wood SIPs cannot be easily modified on site andmust be manufactured to the dimensions required.Many manufacturers offer a range of services, usually fora fee.
