Description

StyroTherm XPS 30mm Slab Insulation — Slim Profile Thermal Break

StyroTherm XPS 30mm is a high-performance extruded polystyrene insulation board. It is engineered specifically for architectural applications where structural depth is strictly limited. Consequently, this rigid foam board provides a highly efficient thermal break without sacrificing valuable site footprint. It delivers a reliable R0.94 thermal rating within a remarkably slim profile. Therefore, it is widely specified across Melbourne for detailed structural junction wrapping and narrow brick cavity walls.

Engineered for Perimeter Slab Edging and High Moisture Zones

This 30mm slab insulation board offers an exceptionally robust compressive strength range of 250kPa to 350kPa. Traditional glasswool batts or expanded foam alternatives frequently degrade when exposed to water. In contrast, extruded polystyrene is completely impervious to moisture due to its high-density closed-cell structure. This physical resilience makes the 30mm profile ideal for vertical placement along concrete slab edges. Specifically, it successfully resists heavy physical impacts during earth backfilling. Furthermore, it prevents dampness from wicking into the building envelope over time.

Key Structural Applications for 30mm XPS Foam:

  • Perimeter Slab Edging: Minimises critical edge thermal loss in residential slab-on-ground foundations.
  • Tight Cavity Walls: Fits seamlessly into slim dual-brick cavities to prevent structural thermal bridging.
  • Structural Column Isolation: Wraps around concrete structural columns to halt temperature transfer effectively.

Sustainable Construction and NCC Compliance

This Australian-made 30mm rigid insulation board is completely free from ozone-depleting substances. For instance, it contains no harmful CFCs or HCFCs. Additionally, the product is fully recyclable. It complies perfectly with the strict energy efficiency standards outlined in the National Construction Code (NCC). In short, choosing StyroTherm ensures long-term thermal reliability and structural integrity under all environmental conditions.
