QSB (Quality Strand Board) is a high quality single-layer particleboard made of specially sorted chips to guarantee compactness and high density of the board across its entire thickness. Humidity resistant MUF adhesives are used in the board production process. QSB CONSTRUCTION BOARDS meet the requirements set out in standard STN EN 312, type P5 for load-bearing boards used in humid conditions.
