Applications

A truly innovative wood-based panel, it is independently certified for the most demanding structural applications in permanent constructions (wall sheathing, flooring and roofing), as well as general free-standing applications where enhanced reaction to fire performance is required, for example:

• Timber frame construction

• Fire protection during construction – see STA FR Build below

• Light Gauge Steel and modular construction systems

• Site security hoarding

• Furniture, shop fitting and general joinery

• Exhibition stands, film sets, stage construction.

Features and Benefits

Reaction to fire classification (Euroclass) of B-s2, d0 and B_fl-s1 (flooring).
CPR Compliant – CE Marked in accordance with EN13986 at point of manufacture unlike post-treated alternatives.
Flame retardant treatment of wood strands during manufacture.
No Added Formaldehyde (NAF) or any harmful substances – contributing to healthier environments.
Reduces fire spread and improves fire protection during construction.
High racking strength – suitable for structural use OSB/3 (EN 300).
Light weight and easy to cut and fix compared to mineral-based panels which can crack and shatter.
Manufactured using FSC® certified timber from our own forests.
Climate Positive – more carbon is stored in the product than was emitted during manufacturing processes (A1-A3). Independently verified Environmental Product Declaration (EPD) available on request.

SMARTPLY MAX FR B also complies with the performance requirements in the Structural Timber Associations “Design guide to separating distances during construction” for timber frame buildings above 600m² total floor area. SMARTPLY MAX FR B can be used in a timber frame building when mitigation measures are required due to the distance from neighbouring buildings.

RIBA Approved CPD

If you are a RIBA Architect and would like to learn more about specifying OSB, we have experienced technical sales managers that are able to present a CPD at your practice to you and your team.

This CPD will focus on how OSB is made, its uses and its certifications, as well as covering examples of how it has been used in these applications. It will also cover the uses and benefits of specialist OSB boards for applications such as drylining and flame retardant panels. By the end of the seminar you should have a greater understanding of:

What OSB is and how it is made
The properties of OSB
The advantages of OSB over alternatives
The various uses of OSB and how it has been modified for specialist applications

FAQs

SMARTPLY MAX FR B are manufactured with the FR chemical added to the wood strands at the same time as the resin during the manufacturing process, thereby locking the fire performance into the panel as a permanent feature throughout the panel. The reaction to fire class B,s2,d0 is certified by an independent notified body following a processing audit and tests in accordance to EN 13501-1.

As SMARTPLY MAX FR B panels are treated during manufacturing the totality of the panel is treated and so the panel will not need to be re-treated after cutting or sanding.

No. The 30- or 60-minutes fire rating relates to the fire resistance of construction systems such as walls, floors, roofs or partitions. SMARTPLY MAX FR B panels can be included in such systems that can be tested to achieve 30- or 60-minutes fire resistance . SMARTPLY MAX FR B panels are classed as flame retardant panels and achieve a reaction to fire class B-s2, d0

SMARTPLY MAX FR B panels can be identified by their dark brown colour compared to the lighter coloured standard OSB panels. This colour is due to the slower speed of manufacture meaning that the panels are exposed to high temperature for longer resulting in a darker coloured OSB.

Class 1 is the Surface Spread of Flame test class in accordance to the British Standard BS 476 part 7, and Class 0 is a Class 1 product that also passes BS 476 part 6: Fire Propagation Test. In the UK, The Building Regulations use the European classification system for reaction to fire set out in EN 13501-1 and provide transposition to national (UK) classes. SMARTPLY MAX FR B have not been classified to BS 476, only to EN 13501-1.
