OSB

We supply OSB across the UK

At Alexander Cleghorn we supply a wide range of Kronospan Oriented Strand Board.

Oriented Strand Board (OSB) is sourced from sustainable materials and made by compressing layers of wood strands and adhesive. Its solid structure makes it an ideal material for flooring, walls and roof sheathing.

OSB Airstop

OSB Airstop core – formed from unsanded OSB board treated with sophisticated film. This board reduces the variations in the heterogeneity, giving precise values of airtightness and water vapour transmission. OSB Airstop allows the installation of reinforced sheathing, an airtight barrier and water vapour in one step.

Characteristics

Increased resistance to humid conditions
High load-bearing capacity and stiffness for construction purposes
High dimensional accuracy and shape stability
High flexibility and impact resistance
Easy workability with popular woodworking tools
Airtightness
Environmentally friendly, recyclable product

Applications

Internal non-load-bearing cladding of walls and ceilings, partitions
Structural roof decking
Load-bearing for ceilings and roofs
Sub-floors and baseboards for flooring systems
Attic conversions or extensions

Standard

EN 300 – type OSB 3; EN 13501-1: class D-s1, d0; EN 13986:2004+A1:2015

OSB Firestop

The core panel of OSB Firestop is OSB 3 board, treated with patented fire-resistant Pyrotite® finish on one or both sides. The Pyrotite® finish consists of magnesium oxide cement, reinforced with a fibreglass mesh.

This board provides load capacity and fire resistance to building structures and are lighter and stronger than plasterboard. With the same thickness, they achieve similar fire properties as sheathing systems based on the combination of OSB and plasterboard.

Using OSB Firestop boards as roof or floor decking saves assembly time and is more cost-effective. When using OSB Firestop as internal lining, the walls and ceilings can only be finished by primer and conventional interior paint.

Pyrotite® technology for OSB boards has more than fifteen years of verified functionality. In contrast to conventional fire protective coatings designed for wood-based products, Pyrotite® does not lose its protective qualities over time.

Characteristics

Easy fixation using conventional fasteners (screws, nails, staples)
Excellent price to performance ratio
High load-bearing capacity and stiffness for construction purposes
High dimensional accuracy and shape stability
High flexibility and impact resistance
Easy workability with popular woodworking tools
The non-flammable surface does not contribute to fire spread and does not form burning droplets
Environmentally friendly, recyclable product

Applications

Cladding in public buildings with increased fire regulations
Internal non-load-bearing cladding of walls and ceilings, partitions
Structural roof decking
Load-bearing for ceilings and roofs
Sub-floors and baseboards for flooring systems
Attic conversions or extensions
Interior decoration, furniture elements, frameworks for upholstered furniture
Production of packaging materials, pallets, shipping containers with high technical demands
Exhibitions (display stands, kiosks)
