INTRODUCTION TO

SARNAFIL MECHANICALLY-ATTACHED S327 ENGINEERED

Sarnafil has three Mechanically-Attached Systems, “Sarnafast®”, “Sarnafil Express” and “Sarnafil Engineered”. Each system uses polyester reinforced S327 roof membrane. S327 is available in three widths; 5-feet (5S327), 6.5-feet (6S327), and 10-feet (10S327). The membrane is fastened directly into the structural deck or the structural framing in any mechanically-attached configuration. The Engineered System is described as follows:


System Description
The Engineered System of mechanical-attachment is the most secure attachment method available. The Engineerd System uses a heavy steel bar (“Sarnabar”) that is fastened over the S327 membrane and into the roof deck or into the structural framing, effectively clamping the S327 in place. The Sarnabar is then covered with a heat-welded, narrow strip of pre-cut S327. Sarnabars are not used in the seam overlap (as done for the Sarnafast System).
The advantage of the Engineered System is that the fastening pattern, both row spacing and fastener spacing within each row, can be customized or “Engineered” for any specified wind load for that building. During periods of high wind load, the Engineered System maximizes the S327 membrane’s resistance to tearing and the fastener’s resistance to pullout and backout. The Engineered System is used on many important facilities. No other manufacturer has the experience that Sarnafil has with this attachment system.
The attached Guide Specification is generic in nature and may be amended as required to meet the project’s needs. Prior to bid, submit amended Specifications with Detail Drawings to Sarnafil’s Technical Department for review and comment.
We welcome you to review the following Guide Specifications and Detail Drawings and we ask that you contact us if you have any questions or need any additional information.
Thank you for choosing Sarnafil for your roofing and waterproofing needs.
