Noraa Block Board
To ensure our commitment to quality Noraa block boards are made from top quality plantation timber logs, which are well seasoned and chemically treated before being converted into battens. The battens are then sandwiched between two mechanically dried veneers and then hot pressed. Noraa block boards are ideal for good strong support to specially wood work, because we believe that.
