M-BLOC® Type C Gypsum Board End Tape

M-BLOC® Type C Gypsum Board

Description

M-Bloc® Type C interior gypsum panels treated with AzoTech™ fungicide were developed as an improved mold and moisture resistant wallboard with additional properties to enhance the core of this type X wallboard to achieve superior performance when used in specific fire rated assemblies.. M-Bloc Type C panels are encased in a mold and moisture resistant blue face paper and brown back paper manufactured from 100% recycled paper.

At an independent laboratory certified in accordance with ISO 17025-2005, M-Bloc panels have been tested to the industry’s most rigorous standard achieving the best possible results per ASTM D3273, scoring a perfect 10 thus minimizing the risk of mold and mildew growth.

American Gypsum products contain no asbestos and no detectable levels of formaldehyde. AzoTech™ is a trademark of a Syngenta Group Company.


Basic Uses

M-Bloc Type C interior gypsum panels are used as a covering material for interior walls and ceilings in residential and commercial applications that often require specific fire rated assemblies. It is designed for direct attachment by screws, nails or adhesive to wood or metal framing. M-Bloc Type C interior gypsum panels can be finished the same as regular gypsum wallboard and they accept a wide variety of attractive finishes.

GREENGUARD Certification

M-Bloc Type C interior gypsum panels have achieved UL Environment’s GREENGUARD GOLD Certification. GREENGUARD Certified products are scientifically proven to meet some of the world’s most rigorous, third-party chemical emissions standards, helping reduce indoor air pollution and the risk of chemical exposure while aiding in the creation of healthier indoor environments.

Technical Data

Storage & Handling

Gypsum board does not generate or support the growth of mold when it is properly transported, stored, handled, installed, and maintained. However, mold spores are present everywhere and when conditions are favorable; mold can grow on practically any surface. GYPSUM BOARD MUST BE KEPT DRY to prevent the growth of mold. Adequate ventilation shall be provided to prevent condensation.

Gypsum board that has visible mold growth must not be used. For additional information refer to Gypsum Association publication, “Guidelines for the Prevention of Mold Growth on Gypsum Wallboard” (GA-238).

Gypsum board must be stored in an area that protects it from adverse weather conditions, condensation, and other forms of moisture. Job site conditions that can expose gypsum board to water or moisture must be avoided.

Gypsum board must be protected during transit with a weather-tight cover in good condition. Plastic shipping bags are intended to provide protection during transit only and must be promptly removed upon arrival of the load. Failure to remove the shipping bag can increase the likelihood of developing conditions favorable to the growth of mold.

Gypsum board must be delivered to the job site as near to the time it will be used as possible. Individuals delivering gypsum board to jobsites should ensure that it is carried, not dragged, to place of storage/installation to prevent damage to finished edges.
