"IN-SEAM" MECHANICALLY-ATTACHED SYSTEM
Unlike adhered roofing systems where the membrane is secured to the system using adhesive, the Sarnafast/In-Seam systems secure the membrane using fasteners within the membrane seam overlap. Typically called an “in-seam” attachment system, after the plates and screws secure the edge of the membrane, the next sheet overlaps the fasteners and is made watertight by hot-air welding the seam.
Below are some of the reasons why a Sarnafast/In-Seam systems might be the best fit for your project.
MECHANICALLY-FASTENED/IN-SEAM SYSTEM BENEFITS:
- Fast and easy installation
- Best for low slope applications
A MEMBRANE DESIGNED FOR MECHANICALLY-ATTACHED APPLICATIONS
The Sarnafil S 327 membrane is a thermoplastic PVC roof membrane used in mechanically-attached systems. Similar to the Sikaplan Fastened membrane, this roof membrane is polyester reinforced, which provides the high breaking and tearing strength needed to prevent excessive elongation and sheet deformation under the stresses produced by the lifting of the membrane by wind in this type of system. Sarnafil membranes are formulated to be the best in the industry with an unmatched proven performance history and multiple third party verified testing data.
