INSULATION SYSTEMS FOR COMMERCIAL BUILDINGS PAGE 17 APPLICATION RECOMMENDATIONS INSULATION SYSTEMS FOR COMMERCIAL BUILDINGS Product Options EcoTouch Flame Spread 25 or Thermal Batt Fiberglass Insulation FOAMULAR XPS Insulation JointSealR Foam Joint Tape Installation & Design Considerations EcoTouch Batts are suitable for installation in the stud cavity. FOAMULAR Insulation is not a structural material so when using, provide adequate bracing for structural framing. Steel stud spacing, 24" o.c. maximum. Between the inside brick face and the exterior surface of the insulation board, provide a minimum of 1" clear space, 1" in residential construction. Use corrosion-resistant masonry ties; connect them directly to steel framing. Install with caulk movement joints, functioning weep holes and adequate flashings. Insulation joints must fit together tightly and should be sealed with sealant or tape recommended by its manufacturer for this application. Building designer should determine the need for and placement of vapor retarders, air barriers and moisture barriers. IMPORTANT NOTE: ASHRAE 90.1 compliance requires the use of a "CONTINUOUS INSULATION LAYER" over the exterior flange of the steel stud. FOAMULAR XPS insulation meets this requirement. JOINTSEALR FOAM JOINT TAPE Product Options FOAMULAR CW15/CW25 Insulation FOAMULAR 250 Insulation Scored Square Edge FOAMULAR High-R CW Plus Insulation JointSealR Foam Joint Tape Installation & Design Considerations Position insulation horizontally between wall ties directly on back- up wall. Tightly fit insulation around vents, louvers, pipes, conduits and other penetrations. Foam insulation board joints should also fit tightly. Install with caulk movement joints, functioning weep holes and adequate flashings. Openings and joints may be sealed with construction tape per tape manufacturers' recommendations. Use corrosion-resistant masonry ties. Maintain a minimum of 1" of clear space between inside brick face and the insulation board's exterior surface. Building designer should determine the need for and placement of vapor retarders, air barriers and moisture barriers.
