RoofNav is a complimentary tool from FM Approvals that provides access to the most up-to-date FM Approved roofing products and assemblies. FM Global through its FM Approvals provides this third-party certification.
Elastizell has over 93,000 individual assemblies listed in FM's RoofNav database with different variables (substrates, membranes, fasteners, etc.).
RoofNav is available 24/7 on their website, www.roofnav.com, and registration is free. Once on www.roofnav.com, click on "register", and after a few short questions, you are in the system. This will allow you to look up products and search for assemblies.
To conduct an efficient RoofNav search, you must be as specific as possible. Vague information will typically result in a large number of assemblies to sort through. Specifications should include substrate (structural concrete or steel), membrane (manufacturer and material), membrane attachment (nailed or fully adhered), and desired wind uplift rating.
