Division 7 Ebook Page 189 Exterior Insulation Finish Systems, EIFS Overview

Section Overview EIFS Insulated Wall Systems CommercialComplete Wall Systems Owens Corning's CommercialComplete Wall Systems provide insulation solutions for the performance demands of Exterior Insulation Finish Systems (EIFS) including energy efficiency, moisture management, indoor air quality, sustainability, and energy and building code compliance. Exterior Insulation Finish Systems (EIFS) Class PM (polymer modified) EIFS, with water resistant, high strength, FOAMULAR 250 insulation, is used for exterior walls in new and retrofit commercial and institutional construction where durable continuous insulation and impact resistance are needed, either directly over steel stud framing or over another sheathing layer such as gypsum board or OSB. Traditionally, Class PM EIFS use extruded polystyrene (XPS) insulation, and a thicker, cementitious base coat applied over mechanically attached lath and glass fiber reinforcing mesh. FOAMULAR XPS insulation is also used in one coat EIFS and traditional stucco systems. Class PB, polymer based, EIFS typically use adhesively fastened lower strength and lower R-value expanded polystyrene (EPS) insulation, and a glass fiber reinforced thin base coat. FOAMULAR XPS Rigid Board Insulation Rigid FOAMULAR XPS insulation, with high resistance to water absorption is perfect for use as continuous insulation in EIFS. It is available with the standard R 5 per inch of thickness, or, R 5.6 in High-R products, with a variety of edge configurations such as straight, ship-lap or T&G. FOAMULAR insulation qualifies as a water resistive and air barrier for code compliance when joints are taped with JointSealR Foam Joint Tape. Steel stud walls with traditional stucco or EIFS cladding comply with NFPA 285 fire test requirements. Consult the EIFS system manufacturer for all system performance details. EcoTouch Fiberglas Batt Insulation Batt insulation products are available in different thicknesses to achieve a variety of R-values in the stud cavity. They are available in either full widths to fill the hollow voids in C-shaped steel studs, or in widths to fit between wood studs. They are either unfaced, or faced with a variety of facers available to address interior vapor resistance requirements. EcoTouch Flame Spread 25 insulation has a durable facer with a flame spread rating of 25, suitable for use exposed, or concealed in non-combustible building types as required by the International Building Code (IBC). Sustainability Owens Corning is committed to driving sustainability through greening our operations, greening our products and accelerating energy efficiency in the built environment. Owens Corning EcoTouch Fiberglas insulation produced with PureFiber Technology, and FOAMULAR XPS products, are GREENGUARD Indoor Air Quality Certified and GREENGUARD Children and Schools Certified SM . EcoTouch insulation products are made with 99 percent natural 1 ingredients and are verified to be formaldehyde free. They are also third party certified to have a minimum of 50 percent recycle glass content. FOAMULAR XPS insulation is also third party certified, to contain a minimum 20% recycled polystyrene content and is produced with Exterior Insulation Finish Systems (EIFS) Continuous Insulation Systems FOAMULAR 250 XPS continuous insulating sheathing ECOTOUCH BATT INSULATION (unfaced) ECOTOUCH FLAME SPREAD 25 INSULATION
