SanteQ Walling Systems

Patent-pending SanteQ lightweight walling systems use a bespoke infill of cementitious materials and 100% recycled polystyrene in a permanent, high-density cellulose fibre board shutter system.

It's green technology, inside and out.

  • 30% the weight of masonry
  • Fire-resistant
  • Excellent sound insulation
  • Excellent thermal insulation
  • Straight, solid walls
  • Water-resistant
  • Fast, clean installation
  • Sustainable technology
  • 100% asbestos-free

SanteQ provides the construction industry with a walling solution that is lightweight, with excellent acoustic, thermal and fire-resistant properties.

It also reduces the environmental footprint. In addition to using cellulose fibre board responsibly sourced from the pulp of farmed trees, SanteQ reuses polystyrene waste and plastic otherwise destined for landfills.

The polystyrene is collected and processed back to bead stage and coated with special admixtures to prevent segregation ensuring a homogenous distribution throughout the concrete, improve pumping efficiencies and retard fire. Recycled plastic is also used in the high-impact spacers.

The result is a high-quality, cost-effective and durable lightweight wall ideal for most non-load bearing applications.

The Process

  • Eco-friendly, high-density cellulose fibre boards are cut to the required wall panel sizes and transported flat to site.

  • High-impact spacers, made from 100% recycled material, are fixed into position between the two fibre boards to provide rigidity and the desired wall thickness.

  • Services are installed and the hollow walls are easy to handle and move into position.

  • The wall panels are quickly and efficiently erected on site.

  • The preblended lightweight concrete composite infill is pumped into the voids.

  • Joints are taped and skimmed and the walls can then painted or otherwise finished.

  • The result is a lightweight yet solid wall offering significantly improved thermal and acoustic properties that has a 2-hour fire rating.
