Secon 7: Fastening
Fiber Cement should be fastened to studs or solid framing a maximum of 24” on center
(o.c.). In some instances, there may not be a stud or framing member available to fasten
into—such as along a rake, inside or outside corners, or at a window or door opening.
In these areas, the fiber cement must be fastened to a structural-rated sheathing. Refer
to te asi Fastening Sedule or aliations in ind ones u to m t

Building codes and regulations vary throughout the country. In some specific situations,
fastening into other structural materials may be acceptable. Refer to local building
codes and/or ICC-ES Report ESR-1668 found on www.AlluraUSA.com for alternative
applications or wind conditions.
All fasteners must be corrosion-resistant, hot-dipped galvanized or stainless steel. Do
not use electro-galvanized nails because they corrode faster, especially in coastal areas.
NOTE: Basic fastening schedule appears on page 34.
