Characteristics of OSB boards ( OSB ) , the advantages and disadvantages of plates of oriented strandboard

OSB stands for Oriented Strand Board - plate from oriented strand board, or OSB in Russian.It is a modern construction and surfacing material composed of 90% wood chips, bonded with synthetic resins, water-resistant.Plates formed of 3-4 layers of thin shavings up to 15 cm, compressed at high pressure and temperature, and the chip area in each layer - the.

Plates OSB can be used for:

• production of sandwich panels and construction of frame houses,
• with shut-off devices, ladders,
• cladding of walls, ceilings, floors,
• for roofing,
• with auxiliary work(installation of casing, forests),
• for the manufacture of auxiliary buildings (sheds, warehouses), outdoor structures, fences,
• as structural elements of furniture.

quality OSB to EN 300 OSB, imposes requirements on environmental safety and technical parameters of plates.

Forms boards and their features

Produced 4 main types of panels:

• OSB-1 - low strength and low moisture resistance, is used for internal work, the manufacture of furniture,
• OSB-2 -high strength and low moisture resistance, is used for internal partitions, load-bearing structures, floors,
• OSB-3 - high strength and high moisture resistance, ideal for outdoor work,
• OSB-4 - ultra high strength and high resistance to moisture,used for bearing members, walls and roofs.

Moisture plate depends on the composition of the adhesive used, and strength - the number of layers and the mutual arrangement of chips in them.

addition, there are plates with lacquered or laminated on one side surface of which, for example, can be repeatedly used for producing the formwork.For laying on a flat surface can be used with the compounds of OSB tongue and groove at the ends with 2 or 4 sides.

The most common standard sizes of plates:

• 122 * 244 cm,
• 122 * 366 cm,
• 125 * 250 cm * 6 -40 mm,
• 125 * 370 cm,
• 125 * 600 cm.

Pros OSB

Manufacturers sometimes called OSB - «advanced» timber.It is the same durable, light and easy to handle, but at the same time devoid of drawbacks such as flammability, susceptibility to rotting and mildew, the presence of voids and knots.For technical properties exceed OSB particle board, MDF and even plywood.

Factory assembly line ensures dimensionally stable and uniform thickness across the plate.OSB provides excellent sound insulation, heat preservation, it is not subject to deformation and destruction of water.For processing it uses the same tools and materials as for timber.Large size sheets allow to build walls with a minimum number of joints.Life of the structure of such panels is almost unlimited.

Cons OSB

Recently found a lot of material about the dangers and negative impact on the health of OSB.All criticism related to the use of phenol in the composition of synthetic resins, which are used for connecting chips and produce carcinogens.To date, the majority of European manufacturers have switched to polymer resins without including formaldehyde and completely safe, such plates are usually marked with ECO, Green-.

for interior works and furniture is permissible to use OSB only intended for domestic work, and if there is any doubt in his capacity as - well insulated plasterboard, interior materials and carpets and take care of ventilation in the room.OSB-3 and -4 may be used only for work outside the home.

products of Russian producers are also gradually comes to a decent level, but the study certificates, the origin of the tar and other details - is necessary.OSB Chinese origin combines low price with the same quality as most are made from low-grade wood and shady pitches, it can be used, except that, for odd works outdoors.
