Environmental Specifications

 

ACQ is an arsenic and chromium-free wood preservative made of copper oxide and a quaternary compound.

It was introduced in North America in 1992 and has a 20-year history of safe, effective use.   Registered by the PMRA of Health Canada, ACQ is the most widely-sold pressure-treated wood in Canada.  ACQ pressure-treated wood is also standardized by the Canadian Standards Association (CSA-O80) and meets all applicable major model building code requirements in Canada.

ACQ is listed by the NAHB's Research Center's Home Innovation Program as an NGBS Green Certified Product for Resource Efficiency and is eligible to contribute points towards the certification of homes and buildings under the National Green Building Standard™.  ACQ wood preservative won the 2002 US EPA Presidential Green Chemistry Challenge Award. Recycled copper is used in the making of the ACQ, reducing the carbon footprint of its manufacture.
