Air Quality Sciences, Inc. (AQS) has developed environmental chamber test protocols that allow manufacturers to understand the levels of volatile organic compound (VOC) emissions released by wood finishes, including stains, sealers and topcoats. These materials can be tested individually or as applied systems on wood. The information produced indicates what VOCs are being released and at what level. It also indicates whether reaction products are present and whether the finish provides a barrier to natural emissions from a wood substrate. Finishing professionals can use this information to determine whether their emissions will be acceptable for use on products to be qualified as low emitting under the new green building guidelines from the National Homebuilders Association and the U.S. Green Building Council's (USGBC) Leadership in Energy and Environmental Design (LEED) program.
