USES 4.1 FOAMULAR® and FOAMULAR® NGXTM Insulation Boards (ASTM C578 Types X, IV, VI, VII, V): FOAMULAR® and FOAMULAR® NGXTM XPS insulation boards are extruded polystyrene foam plastic insulation used as nonstructural insulation on the exterior or interior of above grade walls, door cavities, in ceiling/floor assemblies, on the interior or exterior of below grade walls, below concrete slabs, around concrete slab edges, or as roof insulation. Insulation Boards may be used on the exterior of above grade walls when installed in accordance with Section 6.2 of this report. The insulation boards may be used as insulation under slabs -on -ground, slabs on decks, concrete pavers, and concrete pavers on pedestals when installation is in accordance with Section 6.8 of this report. In areas where the probability of termite infestation is defined as "very heavy" the insulation must be installed in accordance with Section 2603.8 of the IBC or Section R318.1 of the IRC, as applicable. Page 6 of 15 The insulation boards may be used as an alternative to the water -resistive barrier specified in Section 1404.2 of the IBC and Section R703.2 of the IRC when installation is in accordance with Section 6.5 of this report. See Table 1b for further guidance on the intended uses of FOAMULARO and FOAMULARO NGX XPS insulation boards. 5. PRODUCT DESCRIPTION The FOAMULARO and FOAMULARO NGXTM XPS insulation boards are extruded polystyrene foam plastic insulation boards having a flame spread index not exceeding 25 and a smoke developed index not exceeding 450 for thicknesses up to 4 inches and at a maximum density of 3.6 pcf, when tested in accordance with UL723 (ASTM E84) as required by Section 2603.3 of the IBC or Section R316.3 of the IRC, as applicable. FOAMULARO and FOAMULARO NGXTM XPS insulation boards have been found to comply with ASTM C578. The boards are manufactured at minimum densities of 1.30, 1.45, 1.80, 2.20, and 3.00 Ibs/ft3 and have ASTM C578 designations of Type X, Type IV, Type VI, Type VII, and Type V respectively.

The boards must be covered with an approved exterior wall covering. FOAMULARO and FOAMULARO NGXTM XPS insulation boards measuring 2 feet by 8 feet or 4 feet by 8 feet are installed horizontally or vertically with long joints and end joints in contact with one another. When installed directly on framing members, the insulation boards measuring 2 feet by 8 feet must be installed horizontally and framing members are spaced a maximum of 16 inches on center. For wood framing, the Page 10 of 15 insulation boards are attached using 3/8-inch-diameter-head galvanized nails, 1-inch-crown plastic washers or equivalent fasteners long enough to penetrate framing a minimum of 3/4 inch, or through the sheathing, whichever is less. For steel framing, the insulation boards are attached using No. 6, Type S drywall screws with 1-inch minimum plastic washers long enough to penetrate the framing a minimum of 3/4 inch. Fasteners must not be over -driven. Fasteners must be spaced a minimum of 12 inches on center around the perimeter and 16 inches on center in the field. For window installations, the nailing flange is set against sealant bedding and fastened to the framing with galvanized roofing nails 3 inches from each corner and 8 inches on center. Minimum 3-inch-wide flashing is used to seal the sills of windows and minimum 2-inch-wide (50.8mm) flashing is used to seal jambs and heads. Window installation must be in accordance with the window manufacturer's instructions. Flashing of flanged window penetrations must be installed in accordance with Section 1404.4 of the 2018 IBC and Section 1405.4 of the 2015 IBC. The flashing tape must completely cover the framing sill and extend a minimum of 8 inches (203 mm) up the sides of the opening and 6 inches (152 mm) onto the face of the insulation at the front of the window opening. Joints between boards must be covered by minimum 3-'/2-inch-wide JointSealR Foam Joint Tape positioned using hand pressure, and finished with a roller. Penetrations in exterior walls must be sealed with a sealant complying with ASTM C920, Type S or M, Grade NS, Class 25, or with expanding spray foam sealant complying with AAMA 812 as part of the penetration flashing procedure. When the insulation boards are applied over open framing, vertical butt joints must be over framing members. Horizontal joints of foam plastic boards must be tongue -and -groove, or supported by blocking. For cementitious exterior wall coating systems, unbacked joints are permitted only when specified in an approved cementitious exterior wall coating system. It is important that the roof and the interior sides of walls are water -tight prior to application of the air and water barrier system. The manufacturer's installation instructions shall be followed for proper flashing of through -penetrations and fenestrations. 6.6 Use Under Slabs -on -Ground, Slabs on Decks, Concrete Pavers, and Concrete Pavers on Pedestals: FOAMULAR® and FOAMULAR® NGXTM XPS insulation boards may be used under slabs -on -ground, slabs on decks, concrete pavers, and concrete pavers on pedestals when designed in accordance with strength design, load and resistance factor design, allowable stress design, empirical design or conventional construction methods. ACI 360 provides guidance for the design of floor slabs installed over insulation as a slab -on -ground. The insulation modulus specified in Section 13.2.1 of ACI 360 should be determined based on data provided in Table 6.

'For insulation systems that utilize a variety of thicknesses, the system foundation modulus is determined by adding the reciprocal of the foundation modulus of the individual layers. The total is the reciprocal value for the foundation modulus of the entire system. °Recommended stress (load) levels will limit long term compressive creep to not exceed 2% in 20 years. 'Ultimate compressive stress is measured at 10% deformation or yield, whichever occurs first. For thinner product (1 in.), yield typically occurs first. For thicker products (1.5 in. and thicker), yield typically occurs first with 3% to 4% deformation. 7.
