Big Changes to the Lumber Industry

As we move into 2016, we see changes in the pressure treated wood industry. Both the American Wood Protection Association and the ICC Evaluation Service have determined that wood used in many physically above-ground applications needs to be treated to Ground Contact requirements.  


When should a user switch from Above Ground material to Ground Contact material? 

Ground Contact treatment is necessary for physically above-ground material when:

  1. soil or other debris may build up and stay in contact with the wood
  2. there is insufficient ventilation to allow air circulation around the wood
  3. material is installed <6 inches above ground on permeable building materials
  4. material is installed in contact with non-durable untreated or older construction with any evidence of decay
  5. wood is subject to frequent or recurring wetting 
  6. used in tropical climates 
  7. the wood is both: 
  8.                   difficult to maintain, repair or replace and 
  9.                   critical to the performance and safety of the entire system

Joists and beams for decks and docks fit both of these final criteria and therefore require Ground Contact treatment.    


What products does this apply to?  

These changes apply to wood that is treated with all residential preservative systems. ICC-ES approved changes to its Acceptance Criteria for treated wood and these changes will be effective for all products covered by ICC-ES Reports by July 2016. Regardless of whether the similar revisions to AWPA Standards are finalized, these changes reflect the industry direction and should be followed for all products.    


What do I need to do?

These changes ultimately leave decision-making in the hands of builders, consumers and building inspectors to determine if the application requires Ground Contact treated wood. Together, we will need to educate your customers on what material they should stock and how to guide users in selecting the appropriate treated product for their project. The attached flow chart should be a useful tool to help accomplish this.


What does this mean for my warranty?

Beginning in July 2016, material must be used as described above to be covered by Arch's consumer warranty. Arch will supply a revised version of our warranty to ensure our warranty language clearly reflects these standards.
