Standard product features


Standard blank panel: 1200 mm.

Size tolerance (l x w x thickness):

± 3 mm.


A composite panel using the following components:

  • BASF polyurethane PUR core: Closed cell insulation core with a Zero Ozone Depletion Potential (ODP), CFC and HCFC free.
  • Orientated strand board (OSB): Grade 3 BBA approved board, manufactured to BS EN 300, load bearing oriented strand boards for use in humid conditions. Standard external and internal sheet thickness: 15 mm. (Alternative facings can be researched on request).

Fire resistance:

Panel internal and external OSB and CPB facings have Class 1 surface spread of flame to BS 476–7 and are Class 0, as defined by Building Regulations. The panels achieve up to 75 minutes fire rating to BS 476–21 for load bearing walls and 90 minute fire rating for non-load bearing to BS 476–22.

Sound reduction:

- Internal walls:

OSB faced panel plus 12.5 mm plasterboard to each face achieves a weighted sound reduction index (SRI): 40 dB (DnT, w+C, Ctr).

- Party walls (single panel construction):

OSB faced panel plus 12.5 mm sound block and one face with 12.5 mm plasterboard, achieves a weighted sound reduction index (SRI): 46 dB.

Structural loadings:

Varies depending on type of panel, consult BBA for full loading information.


Standard spline joints achieve low air leakage and thermal performance.



Six standard sizes available. Cut lengths to suit between 500–6000 mm also available.
