OSB 3 with tongue and groove Uncut 18 x 675 x 2500 mm

Detailed Description

What are OSB boards

OSB (Oriented Strand Board) is a building board made up of usually three layers of wood fibers that are parallel to the longer edge of the board on the outside, while the middle layer has fibers arranged perpendicularly. The wood grain is bonded together with high temperature and pressure and then glued together with resin. This makes them strong and durable.

Advantages of OSB

• Easy and quick assembly,
• Stability of the material,
• Long service life,
• Maintenance-free
• High durability and strength,
• Good fire resistance,
• Good thermal insulation properties

OSB for safe interiors and furniture

Previously, OSB was manufactured using a formaldehyde binder. Nowadays, manufacturers use binders with polyurethane resins, which are health-safe and safe.

What are the types of OSB

• OSB/1 - for dry indoor environments with a temperature of around 20 °C and humidity up to 65%.
• OSB/2 - are durable and suitable for load-bearing use in dry environments.
• OSB/3 - suitable as load bearing construction boards that can withstand environments with elevated humidity, up to 85%.
• OSB/4 - are the most durable and strongest OSB boards that can withstand the highest loads.

What is OSB RH and PD4

OSB RH refers to OSB with a straight edge.

OSB PD4 refers to boards with perforations on all four sides.

Which OSB to use for the floor

OSB/2 is generally recommended for interior environments with low humidity . However, you can't go wrong if you choose OSB/3, which is more durable and suitable for environments with up to 85% humidity.

Recommended: for convenient and quick installation, choose OSB with a groove.

How thick OSB to use for flooring

The thickness of the building board is also a key factor, matching the spacing of joists and beams.

A few days before installation, move the OSB indoors. This will even out their moisture content and minimize dimensional changes.

How to store OSB

Ensure that OSB boards are not exposed to rain and do not come into long-term contact with soil. If you are not going to install the OSB in the near future, cover them with a breathable, waterproof tarp.

Recommendation: store the building boards horizontally, not upright - they could warp.

OSB and its storage

OSB should be stored horizontally in a well-ventilated area to prevent possible scorching and subsequent changes in wood properties such as discolouration, warping and swelling.
