Tectum Inc. Voluntarily De-Listed from the FM RoofNav Website

Carlisle Construction Materials (CCM) has learned that Tectum Inc. has voluntarily de-listed their decking products from the FM RoofNav site.
 
Tectum Inc. produces structural acoustical roof decks made of wood fiber cement which absorb sound and are compatible with a wide variety of insulation and roofing materials. CCM’s roofing systems are compatible with Tectum decks and share many RoofNav-approved assemblies.
 
Because of the de-listing by Tectum, the FM Approvals for wood fiber cement decks and all related RoofNav listings have been removed from the FM approval site for all roofing manufacturers, not just CCM.
 
Consequently, all wood fiber cement deck ratings listed in Carlisle’s State of Florida Evaluation Reports have been added to the SPRI DORA (Directory of Roof Assemblies) listing website. These ratings will still be applicable and can be specified when using the SPRI DORA directory in lieu of specifying FM approved roof assemblies. Many specifiers use FM approval ratings as a general guide for design, but may be specifying them on buildings which are not insured by FM Global. When specifying for building projects that are not FM insured, the specifier may use SPRI DORA assemblies or UL assemblies.
 
The SPRI DORA listing is a web application database of roof systems tested in accordance with standards referenced in Chapter 15 of the International Building Code (IBC). This service lists wind uplift load capacity on single-ply and modified bitumen roof systems.
