Fine. but how do you know if your floor meets the L/360 standard? We face this in the field all the time. but in remodeling. there`s not always a clear answer. There are published tables for calculating deflection. (including a really cool online calculator at http://www.johnbridge.com/vbulletin/deflecto.pl ) but they assume you have full knowledge of how the floor was built. To be able to use the engineering tables. you`d need to know how far apart the joists are. the length of the unsupported span. how thick the joists are. what type of wood and in what condition the wood is in. as well as how thick the plywood is. if any. Realistically. if all of this flooring is hidden by finished ceilings below and covered over by old flooring layers above. educated guessing takes center stage. The following questions help to determine floor stiffness using common sense guidelines
Ceramic Tile Flooring - Remodeling Over Wood Subfloors. Before you can install a ceramic tile or stone floor. you need to know if the subfloor is even capable of supporting tile. Simply put. tile can be a durable. low maintenance. beautiful floor choice...if it`s on a solid substrate. Or it can be an expensive mistake that cracks. breaks and requires multiple repairs that may never work if the subfloor is not prepared correctly. What factors do you need to look out for to decide if tile is right for your project. and what steps can be taken to insure a trouble free installation?
How thick is the subfloor and what is it made of? In new construction. ¾ inch plywood or Oriented Strand Board is a standard subfloor over joists that are 16 inches on center apart. We find that is almost never enough to meet the deflection standards in most homes. Other times there is old plank flooring beneath a layer of plywood. This is a wild card. since the engineering tables usually don`t include the value for planks in their calculation. but common sense says it does add some stiffness.
If a subfloor displays excessive deflection. it can usually be remedied by installing more plywood on top of it before tile is laid. and by reinforcing the joists from below. While it may make the floor higher than before. think of it as a sort of `insurance policy` against flooring failure.
