Our plywoods are certified to E0 rating which is the lowest emission rating along with California Air Resources Board (CARB) certification issued by Environment Protection Agency (EPA). E0 grade plywood and other wooden boards are allowed to be used in interior environment without extra treatment. In order to reduce the interior environment pollution and protect human health, we have adopted processes and standards to achieve E0 emission to bring safe indoors and ensure your family’s wellbeing.Wellmade plywood is manufactured using a special type of phenol formaldehyde resin on a zero gap lay up system, which reduces the formaldehyde emission from plywood to its minimum value. These boards are then tested and certified, every quarter, by NTA USA and CALIFORNIA AIR RESOURCES BOARD.
