Pinepanels Oriented Strand Board (OSB) produced by Kronospan in Romania (EC) is a performance based engineered, mat-formed panel product made of Spruce, Pine and Beech Wood strands, flakes or wafers and bonded with an exterior-type formaldehyde free PU binder under heat and pressure. High Moisture Resistant MDI/PMDI resin binders are combined with the strands to provide internal strength, rigidity and moisture resistance.
Pinepanels OSB 3 meets or exceeds the performance standards of any Moisture resistant plywood and is also cost effective for uses in interior conditions.
Pinepanels OSB 3 has excellent moisture tolerance and suitable in both dry and highly humid areas of applications and absolutely free from insects and termite infestations in its natural form even without any preservative treatment. In addition, OSB3 has exceptional dimensional stability and a uniform structure with no knots or core voids without any tendencies to warp, twist, cup or bend.
Pinepanels OSB 3 is highly recommended as a structural wood panel and conforms to practically all international standards for applications in Buildings including sheathings and roofing, cabinetries and durable packaging.
Pinepanels OSB 3 is also compliant California ARB regulations Phase 1 and 2, being exempted.
Pinepanels is environment friendly solution in our times to save tropical hardwood forests from extinction and augment the initiatives of sustainable forestry by using the thinning of the plantations as its constituent wood.

Non-formaldehyde synthetic resin MDI/PMDI is used as binder in OSB 3. However, the natural formaldehyde in the veneer strands do emit formaldehyde but such emission is far below the limits set out in EN 13986.
The thermal conductivity (l) of OSB as determined according to BS EN 12664 Thermal performance of building materials and products. Determination o f thermal resistance by means of guarded hot plate and heat flow meter methods. Dry and moist products of medium and low thermal resistance5 is 0.13 W/m.K for a mean density of 650 kg/m3 as set out in BS EN 13986.
Panel sizes commonly available is 2440mm x 1220mm in thickness 12mm & 18mm. Other dimensions can also be arranged with prior arrangement.
Wood Fibers is a living material and is subject to moisture movement according to surrounding conditions, which affects the flatness and thickness swell of panels. .It is important to condition the panels to reach a moisture content near to the equilibrium of their permanent environment. The recommended stocking conditions are 20°C and a RH of air of about 60%.
Wetting of OSB should be avoided. OSB3 is not waterproof; the term ‘moisture resistant’ applies to the adhesive binder which will not break down in the presence of moisture (within BS EN 300 limits).
Like other wood-based panel products, OSB is hygroscopic and its dimensions change in response to a change in humidity. A change of 1% in moisture content typically increases or decreases the length, width and thickness of the OSB by 1% in dimensions and thickness.
The recommended stocking conditions are 20°C and a RH of air of about 60%. The boards should be stored in their intended installation area for a minimum of 48 hours to acclimatise to the surrounding temperature and humidity. Check for any damages before fitting.
Wetting of OSB must be avoided. OSB3 is not waterproof; the term ‘moisture resistant’ applies to the adhesive binder which will not break down in the presence of moisture (within BS EN 300 limits).
All common woodworking tools can be used successfully with Kronospan OSB 3. As a general rule, cutting speeds should be lower than for conventional wood. Carbide or diamond tipped blades and cutters are recommended because of their longer cutting life.
Boards with straight edges need 2-3 mm dilatation gap at the edges of the boards for possible moisture expansion, depending upon the assessment of risk by the users.
Corrosion resistant fasteners should be used where OSB is part of a load bearing structure. Structural fastening systems are only permitted if their use has been approved by the manufacturer.
Guidance on the use of OSB in load-bearing applications is given in DD CEN/TS 12872.
OSB 3 boards must be free from direct exposure to weather conditions, sun light and rains to prevent from weathering and decay.
Physical wetting of all grades of OSB should be avoided. When wet, OSB will increase appreciably in thickness and start the weathering and decay process.
OSB will not normally be attacked by wood-boring insects common in temperate climates as these are susceptible to fungal attack under prolonged wet conditions.
