Ultralam™ OSB products are oriented strand boards of OSB-3 and OSB-4 types distinguished by their high strength and moisture resistance.

  • OSB-3 products — structural boards used in humid conditions.
  • OSB-4 products — high-strength structural boards used in humid conditions.

Emission Class E-0,5

Oriented strand board is a multi-layer sheet formed by pressing rectangular flat chips at high pressure and temperature with exterior type resin binder.

The T&G board owes its name to its tongue-shaped edge fitting into the groove of the adjacent panel. This type of joint ensures easy and fast assembly and substantially reduces installation costs. The usage of T&G OSB-3 boards increases thermal and sound insulating performance by several times due to the limited air and sound penetration through panel joints.

T&G OSB-3 products are mainly used for flooring.

 Ultralam™ OSB panels are available in two edge types:

  • Square edge OSB panels
  • T&G OSB panels

Ultralam™ OSB panels are, first of all, an environmentally safe construction material.

OSB Usage

  • sheathing of interior and exterior walls. OSB panels can be used with all types of interior and exterior finishing materials
  • roof sheathing. Good sound insulation, high stiffness and ability to withstand significant snow and wind loads allow to use OSB panels as an underlayment for shingles, concrete and metal tiling, slating and other roofing materials
  • I-joists – supporting floor and wall structures in timber houses.
  • Manufacturing of SIP panels consisting of two outer OSB layers and a core polystyrene foam layer
  • stiff basis for thermal panels
  • removable formwork for concrete works (multi-use formwork), concrete platforms. Sanded and overlayed OSB panels can be used repeatedly as a concrete formwork
  • subfloor, floor repair. OSB can be used both as continuous flooring and load bearing joists
  • single floor – in light structures OSB panel can be used directly as flooring
  • furniture –frames of upholstered furniture, chairs, cabinet furniture, home built-in furniture (coat closets, shelving units, wall wardrobes)
  • stairs, landings, scaffoldings
  • temporary construction site fencing, coverings for structural openings (windows, doors)
  • shipping crates and pallets, shelving units, exhibition stands, furniture shelves, shop counters, table tops, bill boards;
  • partition walls for ships and railcars
  • structures for auto vehicles, trailer floorings and truck bodies
