DURAGARD ROOFING SYSTEM
CREDENTIALS AND TESTING

Thank you for your interest in the Duragard Roofing Systems. Young Builders would like to offer the following for your consideration: 

Young Builders, in continuing our thirty-year tradition of customer service, has developed the Duragard roof system, which is, by far and above, the finest coated foamed roofing system in the industry based on quality, proven performance and quality/quantity of proven materials (per UL Testing, we exceed the industry standard for “cementitious topped coated foamed roofing,” a standard which we pioneered over 20 years ago). The Duragard roof system was designed and engineered for Arizona and has been installed in the Southwest for over twenty years.            

Though concerted efforts with our manufactures and by utilizing premium materials such as BASF foam insulation and United Coatings Diathon, the Duragard coated foamed roofing system enjoys state of the art fire resistive construction credentials unlike any other.  

UL-790 Class “A” System:

Duragard has UL-790 Class “A” classification over all types of roof deck construction for fire resistive construction methods. The Duragard roof system is not limited to thickness or incline restrictions, as are most foam roofing systems. This means that installing crickets utilizing sprayed in place polyurethane foam insulation at any slope requirement will not affect the required UL-Class “A” Classification. This applies to both combustible and non-combustible decking applications.  

UL Construction Numbers:

UL Construction numbers 74, 82, 136, 181, & 206-U.S. Navy White House Test/UL Standard 1256 (Roof Coatings Classified by Underwriters Laboratories Inc.® as roof deck construction material with resistance to an internal fire exposure only for use in Construction Nos. 74, 82, 136, 181 & 206). 

Factory Mutual (FM) Approvals:

Duragard is approved as a Class 1 Insulated Steel or Concrete Deck Roof System for new construction and as a Class 1 Re-Cover Application System when installed over existing Class 1 built-up roofing. Approval Guild, or job Identification NO. 2NIA3.AM. 

ICBO Approval:

The Duragard roof assembly is supported by ICBO in accordance with the ICBO ES Acceptance Criteria for Membrane Roof-Covering Systems (AC75), data dated 1997; reports of tests in accordance with UL 1256-85 (Wind Uplift Resistance of I-180).  

Fire Resistive Design:

The Duragard coated foamed roofing system complies with UL Fire Resistive Design numbers UL P-733 & UL P-826 for approved metal deck construction and UL P-904 for approved concrete deck construction and can achieve the designated 1, 2 or 3 hour rating. 

Environment:

Certificates from the manufacturer’s of the Duragard system showing that the polyurethane insulation and elastomeric coating system components are VOC compliant and environmentally safe. The Duragard polyurethane foam insulating system is CFC-11 free, HCFC 141b product. The Duragard polyurethane foam insulation is UL 723 tested and rated. 

ISO 9001:

ISO 9001 – Quality Management System of Design and Manufacturer of Polyurethane Chemicals, Specialty Systems and Thermalplastic Polyurethanes and ISO 9002 – Manufacturer, Distribution and Servicing of Microcellular Polyurethane Parts – Through Design by Manufacturer.

ASTM D-6083-97a:

The Duragard coating system is in compliance with ASTM D-6083, which is an all-encompassing test, developed by the American Society for Testing and Materials for the purpose of providing a standard specification for liquid applied acrylic coating used in roofing. The test umbrellas the following ASTM tests that apply specifically to coated roof assemblies: ASTM C-794, D-1079, D-16, D-1653, D-2196, D-2370, D-2697, D-471, D-4798, D-522, D-562, D-624, D-903 and, D-1644.
