How to make a house out of OSB with their hands, without losing the quality and savingfunds?After all, with the same area of the cost of construction, depending on the materials used can vary greatly.And at some construction technology can not do without a powerful rent equipment.The cheapest, fastest and easiest way is considered to frame housing of sandwich panels or OSB.
OSB, or oriented strand 90% consist of wood chips.The remaining components - waterproof resin binder.Get a building panel by pressing large pieces of wood conifers, aspen and larch.Chip size - 15 cm. Inside the future products it is placed in three rows.The outer layers are arranged parallel to the long side of the plate.Middle layer - perpendicularly.Press pressure was so strong that there is a mutual penetration of the fibers.This ensures a high strength of the final product.
resulting material is sometimes referred to as
biggest issues consumers have led to the use of phenol in the composition of mixtures of binders.But now many manufacturers began to move to the polymer resin is completely safe for health.Such a product is labeled labeled "eco" or «Green» on the packaging.

Construction of OSB panels
In the private house-building used 4 types of OSB panels, differing in water resistance, durability and price.
Moisture depends on the adhesive binder and the strength - the relative placement of the chips in its structure.More resistance to all types of influences gives Laminating and Coating the surface.Such plates can be used in the construction of the formwork, and reused.
Type 1. OSB-1 has a small load resistance and hydrophobicity.They take to finish at the inner workings and the manufacture of furniture;
Type 2 OSB-2 is also afraid of water, but much stronger and so is suitable for the construction of partition walls, suspended ceilings, ie those parts where there are large loads and the possibility of getting wet;
Type 3. OSB-3 for creating the outer facade, and they are high-moisture-proof;
Type 4 OSB-4 is very strong, used to build load-bearing elements of walls and roofs, attached to the structure stiffness.
House of OSB is done mostly from 3 types of products.Height - 3 floors inclusive.
Features construction of OSB
- work takes 2-3 weeks without involving heavy vehicles.
- building is not even built, and is going as a designer of ready-made factory parts.They are made to order for a specific project.This means that there will be unexpected expenses and urgent additional money purchasing fees of missing materials and residues difficult to be realized after the completion of all stages.
- OSB boards are much cheaper than brick or foam blocks.
- Frame construction weighs little, almost 5 times less than the brick house of the same cubic capacity.Therefore, the structure does not require a massive and costly foundation.
- in boxes of OSB-3 is already in the production can be laid layers of insulation.Since SIP-made panel.Then, and additional insulation is not necessary.Inside the comfortable temperature is maintained at the outer differential of -40 to + 40 ° C.
- flat surface panels does not require priming and leveling before finishing decorative coating on the walls or ceiling.Unless required Shpatlevanie joints.
- With the technology of the house of RSD do not shrink and distortion.
boards OSB - a versatile material and can be used at any stage of construction.
Foundation. or laminated veneer sheets can be used as a facial foundation boards assembled on the frame of the boards.They are fixed with steel wire ties or fine fittings.
foundation for the house of OSB
Paul. Plates stacked logs on the long side perpendicular to them.Along the perimeter of the panels is left of Technology (dilatation) clearance of 3 mm.It is needed to compensate for thermal expansion or other deformation.Between the walls and floor, too, keep a gap of 12 mm.Sami sheets are fixed using a profile "tongue and groove" and reliability strengthened mounting adhesive.

Connection short sides should always take place on the supports.Under the flooring adjacent to the ground, pull an additional layer of waterproofing.Step between the lags determined by the thickness of the material:
distance between supports mm
walls. Oriented particle products can be mounted vertically or horizontally.When you build a wall, use sheets of 12 mm thick.They rely on the boards at 400 and 600 mm.Between the plates, as well as at the junction to the door and window openings left by 3 mm intervals.For insulation on the outside of the building can be warm mineral wool.
Walls of house from RSD
roof. sheets form a continuous crate, which subsequently spreads roofing.It begins with the installation along the ridge, similar to stacked wood panel floor.Each sheet is fastened so that beneath it were two supports.Joints of plates should also fall on truss joists.
roof is OSB
to sustained roof snow load, the spaces between them are chosen depending on the thickness of the plate:
Thickness mm OSB
Step rafters mm
Due to the properties of the sheet-oriented chip structure does not decay and insects undermined.Fires are also not afraid of him.According to specialists, the life of the house of the panels OSB-3 is the same as a brick.
