Bridging can also be eliminated with resilient finish flooring installed over plywood underlayment and a plywood or wood subfloor. In other words, with resilient flooring, bridging can be eliminated provided plywood underlayment is used.

The FHA office in Washington says the action to omit bridging in these cases was taken because tests indicate bridging contributes little to the total strength of the floor system compared with the strength contributed by the subfloor and finish floor at right angles to joists.

FHA says a plywood underlayment over a subfloor eliminates the need for bridging because it ooprovides for considerable transfer of concentrated loads to adjacent joists."

While the new rulings indicate obvious savings in cost and labor, the Douglas Fir Plywood Association urges builders to use proper grade and type of plywood for underlayment applications. The plywood industry produces a special minimum-cost panel developed specifically to function as a substrato for resilient flooring. This special panel bears the DFPA gradetrademark stamp and the words "Underlayment Grade."

If the Underlayment grade panel is unavailable, any sanded grade of Exteriortype plywood can be substituted. The DFPA does not recommend ordinary Interior-type panels with D.grade veneer.

Both Underlayment grade plyrvood and any sanded grade of Exterior-type plywood require C-grade or better inner plies which can withstand the highly concentrated loads imposed by spike heels on women's shoes and furniture casters.

These inner ply characteristics resist puncture when resilient flooring is applied over plywood underlayment. The DFPA special 2-4-I panel, a combined subfloorunderlayment panel, also has this built-in puncture resistance.
