The OSB or plywood is normally 19/32- to 1 1/8-inch thick. 4 Joists: These lateral wooden framing members rest on foundation walls and beams and provide the structural support for the entire framing system.

Introduction
Purpose
- Flooring underlayment is a thin material that rests between the floor covering above and the subfloor below. Because underlayment is a catch-all term, it can take different forms depending on the flooring material is supports. Unlike the subfloor, which is part of a home's framework and structure, the underlayment serves mostly to provide a flat smooth surface to allow for an easy, …
Construction
- In most major remodeling jobs, the flooring installation will involve laying down some form of underlayment on which to install the surface flooring. But the nature of that underlayment may sometimes be no more substantial than a layer of rosin paper or carpet padding. In brand-new construction, the subfloor may be so sturdy and smooth that carpeting can be laid directly on a …
Future
- More often though, and almost always in remodeling projects, a more substantial underlayment will need to be attached over the subfloor. In cases where the subfloor is in very bad shape, it's even possible that the subfloor itself will need to be removed and a new subfloor layer installed before underlayment and floor covering can be installed. In a bathroom that has seen water dam…
Variants
- There is a trend toward using soft underlayments such as sheets of foam or cork as underlayment materials. Because these do not provide the same kind of structure as sheets of wood or cement board, they really fall into a different class altogether. These are \"floating\" underlayments, which means that they are not attached to the subfloor at all.
Benefits
- Foam and cork underlayments do two things. First, they provide a very slight buffer between the top floor covering and imperfections in the underlying subfloor (or the existing floor, if you are installing new flooring directly over the old). Foam and cork underlayments can smooth out imperfections, such as barely protruding screw heads and small knot-holes.
Use
- These materials probably should not be used as a replacement for a rigid underlayment applied directly over a subfloor, but they can be a good solution when you are installing a new floor covering directly over an old floor that is still in good shape. For example, a layer of foam or cork can work well as an underlayment when you are installing laminate flooring over an existing woo…
Prevention
- Keep your underlayment as thin as possible. Thicker underlayments will begin to pose problems since they can create offset issues between rooms with different flooring materials. Transitions can be problematic if the floor level is substantially higher in one room than in the adjacent room. And in rooms with low ceilings, thick underlayments may ev...
