PRODUCT DESCRIPTIONRmax Thermasheath-3 is an energy-efficient thermal insulation board composed of a closed-cell polyisocyanurate (polyiso) foam core bonded to reinforced aluminum foil facers on each side. Thermasheath-3 utilizes a CFC-, HCFC- and HFC-free blowing agent that has zero Ozone Depletion Potential (ODP) and negligible Global Warming Potential (GWP). This insulation is suitable for use in walls, ceilings and some limited roofing applications in new construction for commercial, residential, agricultural and industrial buildings and in thermal retrofit construction within existing buildings.

Exterior Stucco Construction - Thermasheath-3 may be used as the insulative sheathing under hard coat stucco finishes.It may be secured to the studs with bugle-head screws, galvanizedroofing nails or common-nails driven through cap washers. Cover theThermasheath-3 with a suitable separation layer such as an organic or inorganic felt. Then, attach conventional metal wire lath andexpansion joints with appropriate fasteners as dictated by the local Building Code. Rmax does not recommend the direct attachment ofstucco, such as Portland cement or polymer-modified types, directly to the face of the insulation product. Consult stucco manufacturers for details.

Re-Siding Construction - Thermasheath-3 may be used in retrofit constructionprovided theexistingsiding issoundandsolidlyattached.It is securedwith galvanized nails of sufficient length to penetrate theold sidings, sheathings below and at least one inch into the existing wall studs. Then, cover theThermasheath-3with a suitable new siding ofaluminum,vinyl,fibercement,woodorwoodfiberbasedproducts.

Vaulted Ceiling Construction - Thermasheath-3 may be applied to the inside face of the roof rafters in vaulted ceilingconstruction to provide a layer of continuous insulation (ci) andincrease the R-value of the roof. Simply nail the Thermasheath-3 to thefaceoftherafter,coverwithaminimum1/2inchgypsumwallboard and finish.

Attics and Crawl Spaces - Thermasheath-3 may be applied to the interior face of stud walls or roof rafters within attics and crawl spaces toprovidea layerofcontinuous insulation (ci). Simplynail theThermasheath-3 to the framingmembers and cover with an approvedignition barrier such as 3/8 inch gypsum wallboard or 1/4 inch woodstructural panel, particle board or hardboard.

Concrete Foundations - Thermasheath-3 may be installed horizontally under foundations and vertically inside of the footings. Aseparate vapor retarder sheet should be installed directly against thecrushed stone base and well tamped backfill or undisturbed earth.
