The Best Subflooring Types

If you want to install the best type of subflooring you should take into consideration what type of finished floor you want to have on top of it. The most popular subflooring in wood frame constructions is either oriented strand board (OSB) or plywood. The subfloor thickness depends on the construction design. Plywood is less affected by rain and holds nails and screws better than oriented strand board, but the latter is usually less expensive.

Wood and carpet are installed directly on the subfloor. Any irregularity in a subfloor is most visible through vinyl flooring, so to avoid this it is normally installed over particleboard that has the cracks and nail holes smoothed with spackle. Ceramic tile, marble, and other stone floors are better to be laid over a rigid floor that will not flex and crack the tile or grout. A mortar bed or cement the board is preferred in this cases as subfloor types.

Resilient flooring types are good for rooms that will not be exposed to a lot of moisture, like living rooms, kitchens and bedrooms. In these rooms, people will more likely install tiles, hardwood flooring or laminate.

Carpeting requires certain types of subflooring. The wrong padding may result in a faulty warranty or the carpet getting messed up after being walked on for too long. Carpets are better to install over padding types like frothed foam, foam, waffle rubber, slab rubber, fiber or moisture barriers, to avoid later problems.

Wood and laminate floors also require special subflooring to avoid problems in the material from moisture or mold. Wood and laminate floors are better to install over standard foam, a combo of film and combustion foam, upgraded foam, or cork underlayment to protect the wood or laminate from damages and make it last longer.
