The silicone vapor shield is a very specific tool for a very specific job. It should only be used in situations where the subfloor is either plywood or OSB, and the nail down flooring you are installing calls for a semi-impermeable vapor barrier/vapor retarder (moisture will get through this product). It ultimately depends on what your nail down wood flooring installation instructions call for.
