Benefits - Engineered Wood Products

Increasing the stiffness of a floor system will improve its performance and 'feel'. The most efficient way of increasing the stiffness of the floor is to deepen the joists - this is simple engineering fact - a 25% increase in joist depth will have the same effect as doubling the joist width or halving the joist centres. A clear justification for the 'deeper is cheaper' statement that echoes around the engineered wood product industry. Our designers can easily design the floor to performance levels above the minimum code requirements if so desired.

About Floor Performance

The performance of a floor is matter of opinion. The 'feel' that satisfies one individual may not satisfy another. Many factors affect the perceived performance of a floor. These include:

  • The depth of the joist - The stiffness of a floor can be markedly improved by increasing joist depth. For example, a 25% increase in joist depth will double the floor stiffness.
  • The spacing of the joist system - The stiffness of a floor increases in proportion to reductions in joist spacing.
  • Continuous or simple spans - Allowing joists to span over internal load-bearing walls instead of breaking them at these joints can increase floor stiffness by up to 240%.
  • The decking / flooring material - Thicker decking slightly improves floor performance - 22mm chipboard increases floor stiffness by 2%* compared to 18mm chipboard and means less 'local' deflection under foot.
  • The fixing of the decking material to the joist - Gluing the floor deck to the joists significantly improves floor stiffness, by as much as 70%.*
  • The ceiling material below the joist - Directly applied ceiling boards can improve floor performance by up to 3%.*
  • Level bearings - Unlevel bearings can mean joists feel "spongy" under foot near bearing positions.
  • The location of walls and furniture - The position and size of dead loads on floors can either dampen or exaggerate the dynamic response of floors under foot.
