ABOUT US

Stewart's Plaster Helps

Faster construction
with high-performance panels and blocks that are easy to install

Superior safety
 with fire-resistant, non-combustible material

Sustainable performance
thanks to Hebel’s low embodied energy and thermal efficiency

Traditional masonry can be slow, labour-intensive, and heavy — and standard plasterboard doesn’t always provide the thermal, fire, or acoustic performance you need. Stewarts Plaster combines deep experience in plaster supply with specialised Hebel expertise — so you get both trade-grade advice and efficient delivery.

Many construction projects rely on standard brick or concrete masonry or lightweight plasterboard — but these options come with trade-offs.

Brick and concrete are heavy, slow to lay and require more labour. Standard plasterboard offers lightweight installation but may not meet specialist requirements. That's why Stewart's Plaster supplies both high-performance plasterboard variants — fire-rated, moisture-resistant, acoustic and impact-resistant options — alongside Hebel AAC systems. You get the right material for every application, not a one-size-fits-all compromise."

When left unaddressed, these problems escalate. Delays in construction pile up, material waste increases, and long-term performance issues like poor insulation or fire vulnerability can undermine the quality of your build. That’s where Hebel steps in as a forward-thinking solution.

  • Versatile performance options 
    Choose fire, moisture, acoustic or impact-resistant plasterboard to match specific project requirements
  • Faster installation
    Lightweight plasterboard accelerates construction compared to traditional masonry, reducing labour time and costs
  • Design flexibility
    Create smooth, paintable surfaces for any interior finish whilst achieving the required performance ratings
