These listings are short summaries to serve as a. Estimated range of acoustical performance is based on laboratory test data of similarly constructed assemblies.
Ul rating roof assembly. IBC Section 703 permits multiple ways of determining fire-resistance ratings. More about UL support for code authorities. You can use only the specific type, size, and minimum thickness of Fire Guard™ ceilings or suspension system identified in each assembly.
Class A roof assemblies shall be permitted for use in buildings or structures of all types of construction. Class A roof assemblies and roof coverings shall be listed and identified as Class A by an approved testing agency. The UL Certification Mark on roofing products and assemblies is relied on by code enforcement officials and buyers.
UL's P561 roof assembly allows for a 1, 1-1/2, or 2 hour configuration using either a hot-mopped or cold applied roof membrane and Sure-Span's steel framing joist system. It is based on data and knowledge considered to be true and accurate and is offered for consideration, investigation and verification by the user, but we do not warrant the results to be obtained. In the test, steel balls are dropped on roof shingle samples and the shingles are examined for damage.
1.2 Three classes of fire exposure are described. Only products which bear UL's Mark are considered Certified. UL Designs & Thickness — Roof Assemblies We are inspired to influence how the world is built.
The min truss depth shall be 5-1/4 in. No ceiling or suspension system product alone constitutes a fire-rated assembly. The Dek Design Team® is a full-service technical group dedicated to the engineering, design, and support of Metal Dek Group® products and services in application.
For designers seeking shallower floor and roof depths, the following options exist: Products that receive a Class 4 rating from UL are the most resistant to hail damage. This table is a guide.
Those that have passed UL 1256 may be found in the UL Roofing Materials & Systems Directory. Underwriters Laboratories (UL) 2218 classifies the resistance of roofing products to impact damage. One method is to use calculations in accordance with IBC Section 722.
Both UL and GA emphasize that the fire resistance rating of listed assemblies applies to the assembly in its entirety. Intertek, UL & ULC Ratings provided. This move aligns us with the rest of the industry and will hopefully simplify the fire rated assembly options available.
Components are not intended to be interchanged between assemblies. Size Duct Area per Assembly Construction Design Rating Tiles/Panels Panel System % Ceiling Area 100 Sq. 6 USG Fire-Resistant Assemblies Test Certiﬁcation Test Conditions and Fire- and sound-tested assemblies listed in this Selector are based on characteristics, properties and performance Certificationof materials and systems obtained under controlled test conditions as set forth in the appropriate ASTM Standard in effect at the time of test.
Questions often arise about the construction needed to achieve a Class A, B, or C fire rating for a roof assembly. UL Standards An overview of UL Standards for Safety, how they are developed, and how they related to installation codes and regulations. With a min roof slope of 3/12 and a min.
What are these ratings? * Indicates such products shall bear the UL or cUL Certification Mark for jurisdictions employing the UL or cUL Certification (such as Canada),. IBC section 722.6 could be used to calculate up to a 1-hour rating for a wood-frame wall, floor or roof assembly.
1.3 Class A roof coverings are effective against severe fire test exposures. Additional means to specify fire rated assemblies are as follows: Class A roof assemblies are those that are effective against severe fire test exposure.

View Fire Resistance Approvals on Metl-Span's ThermalSafe Fire Resistant Panels. The previously UL assemblies held by Trus Joist now have a generic I joist specification and can be found on UL directory searches. Roof assembly search tool.
Adhesive — (Optional) — May be applied to steel roof deck units or between insulation layers at a max application rate of 0.4 gal per 100 sq ft. For More Information Class 1 and Class A roof assemblies are not the same. Ask the Dek Design Team ® Let Us Help.
For the most up-to-date fire-resistance ratings, refer to the UL Online Certifications Directory, UL P522. Certification Database — UL Product iQ™. According to the scope of FM 4470:
Where the truss intersects with the We hope the information here will be helpful. See R oofing Materials and Systems Directory-Roof Covering Materials (TEV T).
The Class 1 rating is an exclusive designation that can only be awarded by FM Global, which indicates the successful testing of the entire roof assembly using FM Approval Standard 4470. UL tests rate an entire assembly.
