IN-SEAM, OUT-OF-SEAM AND OUT OF THE BOX
Sika Sarnafil offers the most mechanically-attached system options than any other thermoplastic manufacturer. The reason, because not every building has the same needs or complexities as the other. There is no “one size fits all” roofing system so we go the extra mile and offer you more options so you know you are getting the right system for your project. From standard “in-seam” attachment methods to induction welded attachment methods, the below list of systems will cover you and your investment no matter what the requirements are.
This mechanically-attached system is your best roof system choice when speed and ease of installation are important. Sarnafast features metal plates fastened in the membrane overlap, spaced according to the roof’s wind uplift requirements. It is designed to meet wind conditions on most building types.
The Sarnafil Engineered System is designed for roofs that are subject to severe or extreme wind uplift forces, such as high-rise buildings or facilities located in coastal areas. The advantage of the Engineered system is the fastening pattern – both row spacing and fastener spacing can be customized or “engineered” for any specified wind load. The Engineered System utilizes a specially designed bar which is secured to the structural roof deck with corrosion-resistant fasteners. The bar clamps the membrane fully along its length, uniformly distributing the dynamic load produced by wind uplift. Sika Sarnafil offers wind warranty protection of up to 120 mph with this system.
Sika Sarnafil RhinoBond is an alternative attachment system for Sika Sarnafil roof membranes. The RhinoBond system eliminates membrane fastener penetration by welding the membrane directly to the specially coated plates used to secure the insulation or hardboard to the deck. The result is a commercial roofing system that uses fewer plates and fasteners while enhancing the wind uplift resistance. The RhinoBond system can be fastened directly to an approved roof deck, or into the structural roof purlins like in a metal retrofit application.
