<br />3. SIDE LAP PROCEDURE: Side-lap detail Diagram A, <br />A TF AS recommends butyl sealant tape on all roofing <br />applications. <br /> <br />Pay careful attention that the purlin bearing leg is <br />lapped over as shown in Diagram A. <br /> <br />1. PBR Panel used as siding is side lapped the same as in roof application. <br />R-Panel used as siding has similar side lap method without the purlin <br />bearing leg. <br /> <br />3. Butyl sealant tape is not required for sidelap applications. However, butyl <br />sealant tape is recommended where any closures are necessary. <br /> <br />4. See diagram B view for R-Panel side-lap procedure. <br /> <br />FASTENERS: See Diagram D <br />Consult ATFAB for the specific <br />recommendation of compatible fasteners. Fastener <br />selection is based on the substrate of the specific material <br />chosen for application. <br /> <br />Metal-to-Wood Application: PBR panels are to be fastened to a <br />plywood deck or a plywood deck with purlins by a <br />minimum #9x1-1/2" compatible fasteners. The stitch screw for wood <br />application are #12x3/4" wood-fast stitch. <br />SIDING APPLICATIONS: (PBR & R-Panel) <br /> <br />Metal-to-Metal Application: Attach PBR panels to metal purlins <br />with a minimum #12x1" hex head Tek screw or equivalent. Recommending use of <br />stitch screw for metal application are #14x7/8" metal-fast stitch. <br /> <br />END LAP PROCEDURE: When long panel runs are <br />required, advise end lapping two or more panels <br />to span the required distance. The upper panel should <br />always overlap the lower panel a minimum of 12 inches to <br />insure correct drainage. Two strips of butyl sealant tape <br />should be installed across the panel width for additional <br />weather tightness. <br /> <br />EAVE DETAIL PROCEDURE: Inside PBRlR closures and butyl <br />sealant tape on eave applications to avoid water infiltration. <br />
