If fire-rated party walls are slowing down your builds, costing too much in labour or needing repairs, it’s time to take a serious look at ProBoard, a faster, more cost-effective wall system now available at Dahlsens.
Developed specifically for medium-density and multi-res projects, ProBoard saves you hours on-site, reduces call-backs, simplifies compliance and puts more money in your back pocket.
No fiddly metal channels or complicated systems. Just a smart, durable system that installs fast and stands the test of time.
“It’s very simple and quick to install,” says Daniel Khalaf from ProBoard.
“There are only three components in addition to the panels. The panels are lightweight and chippies find it straightforward to install. You don’t need any specialty trades involved.”
Why builders are switching to ProBoard
- Significant savings
Compared to traditional, plasterboard party wall systems, ProBoard is 15% cheaper on average – and that’s just for the product. - Save time on-site
The shiplap design eliminates the need for metal C-channels and complex fixing systems. ProBoard has just a simple, three-component installation system. “There are no channels,” Daniel explains. “It sits directly on the slab with a bead of fire-rated sealant.” - Lower your installer costs
Lightweight panels that install with standard carpentry tools mean faster installs with your existing crew of chippies. No specialists needed. - Impact resistant
As a magnesium oxide (MgO) panel reinforced with fibreglass mesh, ProBoard is extremely durable and built to withstand impact that may happen on site. - Reduce call-backs and improve peace of mind
ProBoard is mouldproof and water resistant. You can leave it out in the weather and never worry about call backs due to mould at a later date. “It’s designed to reduce labour costs and eliminate all repair costs,” says Daniel. - Compliant and proven
ProBoard is CodeMark certified for steel and timber framing, fully non-combustible (AS 1530.1) and achieves FRLs of 60/60/60 and 90/90/90, helping you meet code with confidence.
- Lighter, smarter, greener
ProBoard is very easy to lift and cut. It’s also made from responsibly sourced MgO, with a lower carbon footprint than traditional alternatives. Choose the system that suits your build.
