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.
GENERAL REQUIREMENTS FOR PARTICLEBOARDS ACCORDING TO STN EN 312

Characteristics
- high dimensional accuracy and dimensional stability
- the same strength in all directions of the board surface
- increased resistance to humid environments
- low thickness swelling
- easy machining with common woodworking tools
- easy fixation using classic fasteners (screws, nails, staples)
- excellent holding of fasteners, also close to the edges
- quick assembly
- advantageous price / utility value ratio
- possibility of ecological recycling
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
