Sarnafil Express Roofing System - Double Weld Attachment

Sarnafil Express Roofing System - Double Weld Attachment

This break-through in mechanically-attached roof systems combines the speed of installation of the Sarnafast system with the wind performance of a double-weld system. Sarnafil Express features a polymer batten strip fastened in the membrane overlap and welded on both sides. The Sarnamatic automatic seam welder, with a patented double weld kit, creates a continuous weld in a single pass on both sides of the batten. This results in symmetrical wind loading across two seams, unlike a single-weld attachment system. Sarnafil Express reduces the chance of fastener rocking and pullout, membrane tearing and seam peeling. This commercal roofing system is ideal for 10-foot wide membrane attachment and buildings that experience repeat high wind events.

Repeat heavy wind events can play havoc with a roof. Be confident the roofing system you specify will perform for years to come by choosing Sarnafil Express.

YOU SHOULD SEE DOUBLE

Double-weld that is. Sarnafil Express combines Sarnafil's time-proven thermoplastic membrane with a polymer batten and fasteners between two welds in the membrane overlap. This breakthrough attachment system provides symmetrical wind loading on two welded seams, unlike single-weld mechanical attachment systems. Sarnafil Express reduces the chances of fastener pullout, membrane tearing and seam peeling. This is especially important with today's wider thermoplastic membranes.

SINGLE-WELD

Single-weld mechanical attachment systems can create fastener rocking and pullout, membrane tearing and seam peeling.

SARNAFIL EXPRESS

Unlike single-weld systems, Sarnafil Express utilizes a polymer batten and fasteners between two welds to maximize wind uplift performance.

GUARANTEED

When you specify Sarnafil Express, you maximize the roofing system's capability to withstand repeat wind events. We guarantee it! Sika Sarnafil stands behind every Sarnafil Express roofing system with a 100 mph wind warranty - hurricane conditions - in our standard warranty.

SAME PRICE

When the wind blows, Sarnafil Express provides superior protection, at no additional cost to the building owner.

Next time you're specifying a mechanically-attached roof, choose Sarnafil Express, Sarnafil's double-weld mechanical attachment system. Your customers will get double-weld security at the single-weld cost. Simple as that. Guaranteed.
