Asbestos cement sheet product production, properties, & uses: this article describes asbestos cement sheet materials including asbestos roofing tiles or shingles, asbestos-cement shingle siding, flat asbestos-cement sheet products such as asbestos millboard and asbestos insulation, and corrugated asbestos sheeting used for both roofing and siding.

    Semi-compressed flat asbestos cement sheets can be found in partitioning in farm buildings, infill panels for housing, shuttering in industrial buildings, decorative panels for facings, bath panels, soffits, linings to walls and ceilings, portable buildings, propagation beds, domestic structural uses, fire surrounds, composite panels for fire.   between exterior walls, vertical fire divisions, fire separations, corridor partitions or any other partitions having at least the same fire resistance rating as the ceiling. All such fire-rated partitions shall be constructed as set forth in section or subdivision (a) of section , as appropriate. The concealed space above such.

Fire-Rated Wood-Frame Wall and Floor/Ceiling Assemblies. Building Code Requirements. For occupancies such as stores, apartments, of-fices, and other commercial and industrial uses, build-ing codes commonly require floor/ceiling and wall assemblies to be fire-resistance rated in accordance with standard fire tests.

This test method measures the ability of the wall system to resist fire penetration from the exterior into the wall cavity or unexposed side of the test assembly under the conditions of exposure.

This test method provides data suitable for comparing the performance of vertically oriented materials, products or assemblies in exterior. Asbestos-cement insulating panels are designed for exterior and interior walls, partitions, curtain walls, roof decks, and for decorative purposes.

All measurements and tests necessary for determining the conformity of asbestos-cement insulating panels with this specification are made in accordance with the methods covered in Section 9. Fire-Rated Type X Drywall Basics.

Fireproof drywall is the pejorative term; its industry name is Type X drywall. The thickness of this drywall is 5/8-inch, including all layers. Glass fibers are added to the board to help it retard fire.

Also, because it is denser than normal gypsum-and-paper drywall, it takes longer for the fire to degrade it. An illustration of an open book.

The fire resistance test results tabulated in Appendix A have been reviewed and c o n s e r v a t i v e l y adjusted to reflect criteria found in the currently accepted ver-sions of consensus-based stan-dard fire resistance test methods.

Without a test specimen present in the tunnel, the ignition flame from the gas jet extends down the tunnel for a distance of 4½ feet from the burners.

In instances where there is a difference, we have noted the variance so that you can make the choice to build for sound or if a fire rating is required, build for fire and know that if tested for sound, results may vary.
