ProBoard Build safer, faster and cheaper with Australia’s #1 Fire rated board.
ProBoard Fireless Party Wall System is an innovative, lightweight, ultra-thin wall system designed to deliver a Fire Resistance Level (FRL) of 60/60/60. Made from high-performance magnesium cement reinforced with glass fibre mesh, these 18mm panels provide exceptional strength, durability, and resistance to mould and water, making them a reliable alternative to plasterboard or Hebel panels.
Unlike conventional plaster, ProBoard’s Fireless Party Wall panels can be safely left exposed to the elements without risk of mould, water damage, or delamination. Suitable for both timber and steel frame construction, this system is CodeMark compliant, offering builders a cost-effective, efficient, and fully compliant solution for internal wall construction.
