Description R-Tech FF (Fanfold) is a high-performance sheathing consisting of a superior closed-cell, lightweight and resilient expanded polystyrene (EPS) with advanced polymeric laminate facers. The core of R-Tech is the same high-quality as our InsulRoof brand insulations, and meets or exceeds the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation. In addition, R-Tech has excellent dimensional stability, compressive strength and water resistant properties. Uses R-Tech FF is ideal in recover applications, and is well-suited for single-ply roof applications that employ mechanically fastened or ballasted TPO, PVC, EPDM and CSPE membranes. Consult local building codes and membrane manufacturers for system requirements. Advantages Labor Savings. R-Tech FF comes in 200 ft2 bundles, and is lightweight enough that the average roof mechanic can carry an R-Tech bundle under each arm (a total of 4 squares). Competing 4’ x 8’ recover products would require 13 sheets to cover 4 squares, and weigh almost 5 times as much as R-Tech FF. Sizes R-Tech FF is available in nominal thicknesses of 3/8”, 1/2” and 3/4” with the 4’ x 50’ FF (2 squares). Individual panel sizes within the FF bundle are 2’ x 4’. R-Tech is also available in 4’ x 8’ units. Installation Recommendations Versatile. The unique polymeric laminate facers allow singleply membranes, including PVC, to be installed directly over R-Tech without additional slip sheets or divorcement. Cost-Effective. R-Tech is typically less expensive than other recover products, requires fewer fasteners per square foot, and is easier to handle. Environmentally Friendly. It contains no formaldehyde or HCFCs, may contain recycled material, and has a foam core that is 100% recyclable. Proven Performance. The same fundamental chemistry has been in use since the mid-1950s, so the actual performance of the product is well known. One fastener is to be placed at each corner of the leading and trailing edges, and thereafter at a rate of one fastener every 12 square feet placed on alternating sides of the sheet. Fasteners are to be 6” from the board’s edge. When used with dark colored membranes, R-Tech should be installed with the silver or metallic side facing up. Note: Some membrane manufacturers may require a higher density of fasteners for their warranted systems. Consult the membrane manufacturer for specific requirements. Water-Resistant. R-Tech is hydrophobic (does not readily absorb moisture) and does not promote the migration of moisture into the insulation. Code Approvals. R-Tech has numerous recover listings with Underwriters Laboratories. Please refer to UL’s Roofing Materials Directory or contact your Insulfoam representative for additional information.
