Rigid Air Barrier

$0.00

Sustainable manufactured and free of harmful chemicals, Magnum Board Rigid Air Barrier provides superior performance and environmental benefits when compared to traditional wood fibre, plywood, gypsum and cement based substrates.

Magnum Board 9mm has passed the P21 bracing test. It measures:

  • Racking strength (how well a wall resists lateral forces)

  • Stiffness (to prevent excessive deflection)

  • Elastic recovery (to avoid permanent damage)

  • Ductility (to absorb earthquake energy) 

Meaning Magnum Board 9mm can be confidently used in bracing walls across your entire build—no special sheets required.
