Comply with the manufacturer’s published instructions for the installation of the membrane roofing system including proper substrate preparation, jobsite considerations and weather restrictions. B. Position sheets to accommodate contours of the roof deck and shingle splices to avoid bucking water. 3.02 VAPOR RETARDERS A. General: The use of a vapor retarder to protect insulation and reduce moisture accumulation within an insulated roofing assembly should be investigated, especially on projects with high interior humidity, such as, swimming pools, breweries, pulp mills, etc. B. In the generally temperate climate of the United States, during the winter months, water vapor flows upward from a heated, more humid interior toward a colder, drier exterior. Vapor retarders are more commonly required in northern climates than in southern regions, where downward vapor pressure may be expected and the roofing membrane itself becomes the vapor retarder. C. On cold storage/freezer facilities, the perimeter details must be selected to provide an air seal and prevent 14 outside air from infiltrating and condensing within the roofing assembly. D. Consult the latest publications by ASHRAE (American Society of Heating, Refrigerating and Air- Conditioning Engineers, Inc.) and NRCA (National Roofing Contractors Association) for specific information. E. If insulation is to be adhered to the vapor retarder with Flexible FAST Adhesive, the 725TR vapor retarder must be compatible and shall be fully adhered to the substrate. Available products include Carlisle supplied “peel and stick” rubberized asphalt membrane with compatible film coating (Carlisle VapAir Seal 725TR Air and Vapor Barrier), and spray or roller applied butyl coatings. Installation requirements for Carlisle’s VapAir Seal 725TR Air and Vapor Barrier are identified in Carlisle published specification. F. VapAir Seal 725TR Installation: 1. Surface Preparation: Concrete shall be in place for 7 days minimum and the substrate must be dry. The surface shall have a smooth finish and be free of voids, spalled areas, sharp protrusions, loose aggregate, latence and form release agents. In the event of rain, concrete must be allowed to dry before primer is applied. 2. Primer: Surfaces to receive Carlisle VapAir Seal 725TR Air and Vapor Barrier must be clean and dry. Prime with CCW 702 or 702LV or Cav-Grip III Primer. Apply Primer by spray, brush or with a long nap roller at the applicable coverage rate noted above. At 75° F allow primer to dry 1 hour minimum. Primer has a satisfactory cure when it will not transfer when touched. Prime only areas to be waterproofed the same day. Re-prime if area becomes dirty. 3. Application: Apply Carlisle 725TR Air and Vapor Barrier from low to high point, in a shingle fashion, so that laps will shed water. Overlap all edges at lease 2-1/2". End laps shall be staggered. Place membrane carefully so as to avoid wrinkles and fishmouths. Immediately after installation, roll with a 30” wide, 150 pound weighted segmented steel roller. 4. Insulation Installation: Ensure surface of Carlisle 725TR Air and Vapor Barrier is dry prior to installing insulation. Place insulation over the surface and mechanically fasten to the roof deck or adhere to the vapor barrier with Flexible FAST Adhesive in accordance with this Carlisle Specification. G. For metal decks, VapAir Seal MD Air and Vapor Barrier is specifically designed for direct application to fluted steel decks. It may also be used in conjunction with either Carlisle’s CAV-GRIP on vertical wall surfaces, such as structural concrete, gypsum, Securock, DensDeck Prime and plywood substrates. H. VapAir Seal MD Installation: 1. Surface Preparation: The surface shall have a smooth finish and be free of voids, spalled areas, sharp protrusions, loose aggregate, laitance and form release agents. In the event of rain, concrete must be allowed to dry before primer is applied. 2. Primer: Surfaces to receive VapAir Seal MD Air and Vapor Barrier must be clean and dry. Prime with CCW 702 or 702LV or Cav-Grip III Primer. Apply Primer by spray, brush or with a long nap roller at the applicable coverage rate noted above. At 75° F allow primer to dry 1 hour minimum. Primer has a satisfactory cure when it will not transfer when touched. Prime only areas to be waterproofed the same day. Re-prime if area becomes dirty. 3. Application: Apply VapAir Seal MD Air and Vapor Barrier to the metal deck from low to high point, in a shingle fashion, so that laps will shed water. Overlap all edges at lease 2-1/2". End laps shall be staggered. Place either a 6” wide section of 24 gauge sheet metal or a 6” wide section of VapAir Seal MD directly on the metal under each end lap, perpendicular to the end lap, to ensure a solid surface to roll the end lap together. Seams and end laps must be rolled with a 2” seam roller or stand-up seam roller. Place membrane carefully so as to avoid wrinkles and fish mouths. Immediately after installation, broom the sheet to ensure proper contact to the metal. 15 4. Insulation Installation: Ensure surface of VapAir Seal MD Air and Vapor Barrier is dry prior to installing insulation. Place insulation over the surface and mechanically fasten to the roof deck accordance with this Carlisle Specification. 3.03 INSULATION PLACEMENT A.

Stagger joints both horizontally and vertically if multiple layers are provided. B. Insulation shall be loose laid over the substrate in accordance with the manufacturer’s specifications. 3.04 MEMBRANE PLACEMENT A. Unroll and position membrane without stretching. Allow the membrane to relax for approximately 1/2 hour prior to splicing. B. Install adjoining membrane sheets in the same manner, overlapping edges approximately 4 inches. 3.05 MEMBRANE SPLICING A. Position membrane sheet to allow for required splice overlap. Mark the bottom sheets with an indelible marker approximately 1/4” to 1/2” from the top sheet edge. The pre-marked line on the membrane edge can also be used as a guide for positioning splice tape. B. Fold the top sheet back and clean the dry splice area (minimum 3” wide) of both membrane sheets by scrubbing with clean natural fiber rags saturated with Sure-Seal Primer. When using Sure-Seal (black) PRE- KLEENED membrane, cleaning the splice area is not required unless contaminated with field dirt or other residue. C. Apply Sure-Seal EPDM Primer or Low VOC EPDM Primer to splice area and permit to flash off. Primer must be applied to both the top membrane layer and the bottom membrane layer. D. When adhering Factory Applied Tape (FAT), pull the poly backing from FAT beneath the top sheet and allow the top sheet to fall freely onto the exposed primed surface. Press top sheet on to the bottom sheet using firm even hand pressure across the splice towards the splice edge. E. For end laps, apply 3” or 6” SecurTAPE to the primed membrane surface in accordance with the manufacturer’s specifications. Remove the poly backing and roll the top sheet onto the mating surface. F. Tape splices must be a minimum of 2-1/2” wide using 3” wide (Butyl/EPDM) SecurTAPE that is a minimum 25-mil thick. SecurTAPE must extend 1/8” minimum to 1/2” maximum beyond the splice edge. Field splices at roof drains must be located outside the drain sump. Note: For projects where a 20-year System Warranty is specified, splice enhancements are required. Refer to Carlisle’s EPDM Roof System specification. G. Immediately roll the splice using positive pressure when using a 2” wide steel roller. Roll across the splice edge, not parallel to it. When FAT is used, Carlisle’s Stand-Up Seam Roller can be used to roll parallel to the splice edge. H.
