Ceramic Tile Deflection Limits

The subfloor areas over which stone tile is to be applied must be designed to have a deflection not exceeding l 720 of the span.

Ceramic tile deflection limits.

These deflection limits apply both to the framing supporting the substrate and to the substrate itself for example when a concentrated load is applied between joists. Learn more about it here. Please read everything on the attached photo below. The tile council of america recommends that deflection be limited to l 360 l span length in inches under total load for ceramic tile.

The l stands for length. Whether you are installing stone or ceramic tile over floors and walls there s one thing to consider. Until recently the tile council had specified a standard for ceramic tile only based on using test equipment that was intended to limit deflection of floor sheathing. 100 clemson research blvd anderson sc 29625 phone.

Mia suggest in their standards to use a stricter total load deflection limit of l 720 where stone tiles are used. Ceramic tile live load deflection shall not exceed l 360 stone tile live load deflection shall not exceed l 720 the owner should communicate loading requirements to the designer designer and contractor must make allowances for all live and concentrated loads including during construction and maintenance such as heavy. And since it is small i will leave the source for where it is found here 1. Tile industry associations recommend special total load deflection limits the following tables list the components and weights of typical floor systems along with the deflection limits that apply.

However the limit of span 360 was often misunderstood as the same limit for framing members specified by the building code.
