Due to the no formaldehyde added resin (NAF) being used, ECO-Board panels have emissions far below the strict E0 European low formaldehyde (LF) and the USA (HUD 24) CARB standards. ECO-Boards are suitable for use in environmentally sensitive areas such as
· nurseries
· children's furniture
· hospitals
· public buildings
· laboratories
· nursing homes
or any domestic application with concern for the living environment and sustainable lifestyle. The Beijing Olympic Gymnasium eco-strawboards were used.
