INSULATION SYSTEMS FOR COMMERCIAL BUILDINGS PAGE 9 CURTAINWALL INSULATION FIBERGLASS INSULATION-PRODUCT DATA DESCRIPTION, USES & DESIGN CONSIDERATIONS Unfaced Faced (FSK) Provides thermal performance in curtainwall spandrel systems when placed between or over framing members and held in place with mechanical fasteners. Semirigid, board-like fiberglass insulation is available unfaced or FSK (foil-reinforced kraft) faced in thicknesses from 1" to 4". (Evaluate the use of vapor retarders based on the project requirements.) Equip curtainwall buildings with sprinkler systems for fire protection as required by building codes. FEATURES & BENEFITS The standard size is 24" x 48"; nonstandard lengths and widths are available. Accommodates most thermal specifications. Will not decay or slump within the wall cavity, and its fibers will not shrink or warp. INSTALLATION Impaling pins, if used, should be 3" to 8" from the edges. Follow pin manufacturer's recommendations. Cut with a utility knife and fit into irregularly shaped areas. Install on impaling pins, friction-fit between furring strips, or install with appropriate adhesive. Seal joints and repair facing tears and punctures with a pressure-sensitive foil tape. Keep product dry. Use adhesives appropriate for lightweight board insulation. Follow manufacturer's recommendations. APPLICABLE STANDARDS ASTM C518 tests determined R-values. * Listed R-values are for insulation only. Surface burning characteristics were determined with ASTM E 84, a standard used solely to measure and describe properties of products in response to heat and flame under controlled laboratory conditions. The results are not intended to reflect hazards presented under actual fire conditions. Complies with ASTM C612, Type 1A/1B. ASTM C 612 replaces Federal Specification HH-I-558B. NRC data produced through ASTM C423 testing. Facing permeance determined through ASTM E96 (desiccant method) and the MEA 87-84 requirements of New York City.
