  • Why use ProWood pressure-treated lumber?
    Lumber's greatest enemy is biological attack — destruction by termites, fungi and marine borers — as well as damage from rain, sun and wind. Thanks to over 50 years of research, ProWood can stand up to every threat for decades of use.
  • How do I know if the treated wood I'm using is properly treated for my intended use?
    Look for a lumber end tag. Each piece of ProWood lumber has a tag containing information regarding the preservative used, the appropriate end use (i.e. above-ground or ground contact), the quality standard and safe handling instructions.
  • Is it okay to install an under-deck ceiling system to my elevated wood deck?
    If you intend to install an under-deck ceiling system, the general guidance is that the homeowner/builder must ensure that the ceiling system is well ventilated, drainage systems have proper slope and the system prevents debris from accumulating. The homeowner must use building code compliant ground-contact treated materials (UC4A) for all parts of the structure, including the decking. Systems with poor ventilation (or no ventilation) should not be used, as even ground-contact pressure-treated lumber may not provide adequate service life.
