Ceramic Tile Deflection Limits

And since it is small i will leave the source for where it is found here 1.

Ceramic tile deflection limits.

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. The l stands for length. The tile council of america recommends that deflection be limited to l 360 l span length in inches under total load for ceramic tile. 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.

So if you have a beam 20ft long the allowable deflection limit is 20ftx12in ft 240 1. Mia suggest in their standards to use a stricter total load deflection limit of l 720 where stone tiles are used. Learn more about it here. Mia installation general information 3 8 3 frame construction.

Please read everything on the attached photo below. 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. Some large natural stone tiles that aren t as uniformly strong as ceramic tile may require an even stiffer structure. 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.

Whether you are installing stone or ceramic tile over floors and walls there s one thing to consider.
