The Truth About AWPA Standards
Recent changes to the American Wood Protection Association (AWPA) standards have led to the misconception that all deck framing, including joist and beams, must be treated to Ground Contact retentions; this simply isn’t true. The AWPA standards do not require all joists and beams to be treated to Ground Contact (UC4A) retentions, and Above Ground treated wood (UC3B) remains IBC and IRC code compliant for common deck framing applications.
THE VIANCE WARRANTY
Opposed to other companies, we stand behind our preservative treatments by continuing to provide a Lifetime Limited Warranty on Above Ground treated wood products. Our new warranty enhancements include slight variations of the following statement:
Viance warranty coverage includes Above Ground treated wood framing members that are critical to the safety and performance of the structure, including joists and beams.
RESIDENTIAL PRESERVATIVES WARRANTIES
FIRE RETARDANT TREATED WOOD WARRANTIES
INTERIOR FRAMING WARRANTIES
INDUSTRIAL · COMMERCIAL WARRANTIES
The VIANCE DIFFERENCE
The recent modifications to the standards language has created confusion in the marketplace with builders, retailers and code officials. We strongly believe that wood treated to the AWPA’s Above Ground (UC3B) standard and used appropriately, will perform.
Enhancements to our warranties clarify our general industry position; Above Ground treated wood, treated to AWPA standards and used properly, should meet customer safety and performance expectations without the need to introduce excessive amounts of chemicals into the environment, or to potentially increase costs unnecessarily.
