What Is CDX Plywood?
CDX plywood is a structural softwood plywood classified by its veneer grades and glue type:
- C face — allows knots, repairs, and natural defects; utility grade, not for appearance
- D back — lower grade back; structural use only
- X (Exterior glue) — moisture-resistant adhesive that holds up to weather exposure during construction
CDX is not rated for permanent exterior exposure without cladding or roofing — it is a structural sheathing panel designed to be covered by siding, roofing, or flooring. For applications requiring permanent moisture resistance, specify pressure-treated plywood or marine plywood.
CDX Applications in South Florida Construction
Roof Sheathing
CDX is the standard sheathing panel for residential and light commercial roofing in South Florida. Hurricane-strapped roof assemblies require properly specified sheathing thickness — 5/8″ and 3/4″ CDX are commonly specified for high-wind zones in Miami-Dade and Broward.
Wall Sheathing
Used as structural wall sheathing behind stucco, siding, and exterior cladding systems. Provides racking resistance and a nailing surface for cladding.
Subfloor
3/4″ CDX (or tongue-and-groove Sturd-I-Floor) is used as subfloor decking over floor joists in wood-frame construction.
Concrete Forming
Lower-cost CDX is used for single-use concrete forms, temporary shoring, and site work where the panels will not be reused. For reusable forms with smooth concrete finish, specify MDO plywood.
Sizes & Thicknesses

Frequently Asked Questions — CDX Plywood Miami
What CDX thickness is required for Miami-Dade hurricane-rated roofing?
Miami-Dade County’s high-velocity hurricane zone (HVHZ) building code requires specific sheathing specifications — typically 5/8″ or 3/4″ CDX with 8d nails at 6″ on center at panel edges.
