Ceramic Tile Deflection Limits
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.
Ceramic tile deflection limits. So if you have a beam 20ft long the allowable deflection limit is 20ftx12in ft 240 1. 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. Whether you are installing stone or ceramic tile over floors and walls there s one thing to consider. 100 clemson research blvd anderson sc 29625 phone.
Mia installation general information 3 8 3 frame construction. 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. 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. Some large natural stone tiles that aren t as uniformly strong as ceramic tile may require an even stiffer structure.
The l stands for length. 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.

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