M-BLOC Ekcel Type X Gypsum Board

American Gypsum’s patented 1/2” M-Bloc Ekcel® Type X gypsum panel was developed as a fire resistant, mold and moisture resistant wallboard for use in the patent pending 2-1/2 hour fire rated ME Area Separation Firewall System. The M-Bloc Ekcel® Type X panel is encased in a mold and moisture resistant blue face paper and brown back paper, that has been tested to the industry’s most rigorous standard, ASTM D3273 (Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber) 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. 

1/2” M-Bloc Ekcel® Type X gypsum panels are used in conjunction with metal framing members for the patent pending ME Area Separation Firewall System.

Technical Data

Storage and Handling

The 1/2” M-Bloc Ekcel® Type X gypsum panels must be stored off the ground with sufficient risers to assure support for the entire length of the wallboard to prevent sagging, and under protective cover in accordance with the Gypsum Association’s technical bulletin, Handling and Storage of Gypsum Panel Products (GA-801).

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 should be delivered to the job site as near to the time it will be used as possible.
