QSB Construction Board

Characteristics

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.

Usage

BUILDING AND CONSTRUCTION APPLICATIONS:

  • load-bearing wall or roof sheathing
  • ceiling construction shutters
  • subfloors and bearing plates in flooring systems
  • internal non load-bearing wall and ceiling sheathing, panels
  • roof superstructures
  • fencing around a construction site
  • shuttering: sacrificial shuttering, foundation shuttering, prefabricated elements shuttering, etc.

 

FURNITURE MAKING APPLICATIONS:

  • sheathing in rooms with increased humidity
  • frames for upholstery, doors and windows

 

PACKAGING INDUSTRY:

  • sheathing and manufacturing of transportation boxes, packages, and containers with high technical load-bearing and shock-proofing requirements
  • manufacturing of shelves and racks
