There are formulas used in the industry to determine if the subfloor has excessive `deflection` [bounciness. lack of rigidity]. The most cited one is the Tile Council of North America standard for deflection. which is stated as L/360 as a minimum. before tile underlayment is installed. L/360 means that the floor should not bend under weight more than the length (expressed in inches) of the unsupported span divided by 360. For example. if the span between supports runs for 20 feet then the deflection should not be more than 2/3" between the center and the end. L=20 x 12" = 240". L/360 = 240"/360 or 2/3". So 2/3" is the maximum amount of movement the center of the span should be allowed to move.
This article talks about garage tile flooring and the advantages and disadvantages you should consider before installing it in your garage. Tiles date back to the middle ages and have always been a popular flooring option. From the simple to the ornate choices are virtually limitless and you can have a field day choosing your tiles.
It is adaptable to any decor. Tile can create the foundation for your decorating theme. or become the final accent in your room motif. Tile is now available in finishes and shapes that lend themselves to any décor. Ceramic tile can appear Southwestern. starkly contemporary or smoothly traditional. Colors range from lively to subdued; textures vary from classically smooth to antiqued markings. Imagine a color and texture and you will almost certainly find it on the market today. Tile goes with other flooring. Tile next to wood can be a distinctive look. as brilliant hardwood in one room is married to elegant ceramic in the next. This combination effect will also divide large open spaces into smaller living areas.
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.
