Great value for money and yet strong and reliable, OSB represents a credible alternative to plywood. It is produced in a number of specifications and is highly versatile.

SMARTPLY OSB3 – ideal for environments where there is greater humidity, this panel is more suited to construction and house building applications.

SMARTPLY OSB4 – an extremely high-performance engineered wood panel suitable for the most demanding structural applications in offsite manufacturing and construction.


SMARTPLY SITEPROTECT is a highly engineered and improved moisture resistant OSB/3 coated panel specifically designed to save both time and money in the most demanding hoarding applications. The substrate is coated with a smooth, heavy duty, exterior, cross-linked polymer surface treatment making it ideal for use in a wide range of applications from temporary hoarding through to long-lasting site security installations.


As with all site hoarding panels, the performance of SMARTPLY SITEPROTECT will depend on the time and severity of exposure to the elements. Slight distortion of panels may occur as a result of extreme exposure and poor site workmanship. Therefore, to obtain the optimum performance and life expectancy of the product; good specification, planning and workmanship is required.


SMARTPLY SITEPROTECT is available in 2440 x 1220mm panels and the panel thickness is 18mm.


SMARTPLY PATTRESS PLUS is an engineered OSB3 panel incorporating a continuous recess, designed to accommodate ‘C’ shaped metal studs used in the construction of plasterboard partitions.

It is tested to the relevant sections of BS5234 Part 2 demonstrating high pull-out strength. SMARTPLY PATTRESS PLUS is an OSB3 panel with zero added formaldehyde and therefore may also be useful in environmentally sensitive interior applications such as hospitals, laboratories, museums and schools.

Manufactured in accordance with EN300, CE marked and FSC approved, SMARTPLY PATTRESS PLUS is a fully certified alternative to tropical plywood.
