INSULATION SYSTEMS FOR COMMERCIAL BUILDINGS PAGE 11 FIBERGLAS 700 SERIES INSULATION FIBERGLASS INSULATION-PRODUCT DATA APPLICATION RECOMMENDATIONS Types 701 and 702 are lightweight, unfaced, flexible insulations in batt form for use on vessels having irregular surfaces, where compressive strength is not a performance criterion. Types 703, 704 and 705 are board insulations usually impaled over welded pins on flat surfaces. Unfaced boards are normally finished with reinforced insulation cement or weather- proof mastic. ASJ-, FSK- or faced insulation boards shall be applied using mechanical fasteners such as weld pins or speed clips. Fasteners shall be located not less than 3" (75 mm) from each edge or corner of the board. Pin spacing along the equipment shall be no greater than 12" (300 mm) on center. Additional pins or clips may be required to hold the insulation tightly against the surface where cross breaking is used for stiffening. Weld pin lengths must be selected to ensure tight fit but avoid "oil canning." In multiple layer applications, use faced material on outer layer only. Where a vapor retarder is required, cover pins and clips with vapor sealing, pressure-sensitive patches matching insulation facing. Rub hard with a plastic sealing tool to ensure a tight bond and a vapor seal. All insulation joints should be sealed with pressure-sensitive joint sealing tape to match the insulation facing. Rub hard with a plastic sealing tool to effect a tight bond. Recommended practice suggests a 3" (76 mm) wide tape on flat surfaces or where edges are shiplapped and stapled. Use 5" (102 mm) wide tape in lieu of shiplapping. If insulation is being applied to sheet metal ductwork, all sheet metal joints must be sealed prior to insulating. Glass fabric and mastic may be used in lieu of pressure sensitive tape. May be installed in either single or multiple layers up to a maximum of 6" (152 mm) at temperatures not over 450F (232C).

Values are based on horizontal heat flow, vertical flat surface, 80F ambient temperature, still air, ASJ jacket. To convert heat loss values to W/m 2 , multiply values by 3.15. To convert surface temperatures, use the formula: C = (F-32)/1.8.
