Why Plywood for Floors?


Plywood for Floors

Versatility

  • Allows homeowners the option to change floor coverings as their lifestyles change, whether they want hardwood, carpet & pad, ceramic or vinyl tile

Plywood for floors

  • Stiffer, firmer feeling floors
  • Up to 10% stiffer than OSB at equal joist spacing - decreasing the probability of ceramic tile cracking and soft, springy floors

Durability

  • Holds up better than OSB under incidental wettings, such as appliance overflows

Appearance

  • Real wood veneer
  • No surface flaking to show through floor coverings

Quieter floors

  • The ultimate nail withdrawal strength of 23/32" plywood is 15-20% higher than 23/32" OSB
  • Holds hardwood flooring firmly
  • Minimizes nail pops and squeaks

Greater point impact resistance

  • More resilient (less brittle) than OSB
  • Withstands life's "hard knocks" better with minimum punch-through due to heavy impact loads dropped on the floor

Preferred under ceramic tile

  • Both the TCA and NTCA (Ceramic Tile Associations) recognize plywood as the "preferred" sub-floor panel under backer board when applying ceramic.
  • 10% stiffer than OSB - decreasing the probability of ceramic tile cracking

Superior long-term load-carrying ability

  • Will deflect (sag) less than OSB over time under high humidity, helping floors stay flatter longer than OSB - maybe for the life of your home!

Excellent base for adhesion

  • Has an all wood surface - no wax results in better adhesion than OSB
  • Holds laminate hardwood flooring or vinyl tile better

Lighter panels

  • Weighs 15% less than OSB Sturd-I-Floor of the same thickness
  • Less stress on the floor framing

Proven

  • More than forty (40) years of reliable performance and certified APA quality

Lifetime Limited Warranty

  • Original homeowner protection for floors and roofs as long as you own your structure (See actual warranty)

1 Information concerning stiffness provided by the APA - The Engineered Wood Association, Panel Design Specification, D510A. Information concerning nail withdrawal strength provided by the APA - The Engineered Wood Association, Report T2001-3A, direct withdrawal for a 6d common nail.
2 Stiffness. 23/32" plywood is 10% stiffer than 23/32" OSB. The result? Less deflection and sag under heavy loads.
3 Nail withdrawal strength. 23/32" plywood holds fasteners more firmly than 23/32" OSB - a 36.5% greater nail withdrawal strength for a 6d common nail. The result? Less nail pops and floor squeaks.
