Heavy-Duty Industrial Protection

Alufoil® FR Double-Sided Heavy Industrial Grade is a robust, high-performance thermal barrier engineered to deliver exceptional durability and superior structural rigidity compared to standard woven matt foil laminates. This heavy-duty membrane features a high-strength, multi-layered aluminium foil laminate reinforced with a fiberglass scrim to withstand the rigors of large-scale construction. Incorporating highly advanced fire-retardant properties with pure aluminium foil on both sides, it is the ideal choice for heavy industrial warehouses, large commercial projects, and residential developments. Its market-leading pace-to-area ratio installation methodology drastically cuts down on-site labor time and costs. Built for maximum longevity, this environmentally friendly barrier requires zero maintenance, will not readily age, and is fully non-hygroscopic—ensuring it never absorbs moisture or sustains fungi, mould, bacteria, or vermin.

 Tough Structural Applications

  • Industrial Steel Over-Purlin Systems: Laid securely over 1.6mm galvanised steel straining wires spaced at 367mm centres, with the first wire positioned 50mm from the gable end. Sheets feature a tight 100mm overlap and are held firmly using GDA grade double-sided tape on the eave and apex purlins before final roof sheeting is fixed.

  • Truss & Tiled Roof Layouts: Installed horizontally across rafters or trusses from eaves to ridges with a 100mm structural overlap. The material is pulled perfectly taut and securely stapled using industrial-grade staples right before the tile brandering is attached.

Problem-Solving Profile

  • Solves Structural Sagging & Tearing: Engineered with premium material density to offer excellent rigidity and heavy-duty tensile strength, ensuring the material remains flat and taut across wide purlin spaces without tearing or stretching out of shape during rough installations.

  • Solves Strict Industrial Fire Compliance: Packed with advanced fire retardants to secure the highest fire rating for multi-layered aluminium foil roof insulation products, certified to SANS 10177 Part 5 & 10 (A/A1/1 H&V – SP & USP) and SANS 53501-1 (B-s1, d0) standards.

  • Solves Thermal Inefficiency & Dim Interiors: Provides maximum compliance with SANS 10400XA energy efficiency regulations to slash cooling costs, while its ultra-low emissivity, high-reflectivity silver surfaces bounce light effectively to dramatically brighten massive open facilities.

Quick Technical Specs

  • Material Density & Heavy Weight: High-density 251gsm material mass with a heavy-duty, stable roll weight of approximately 12kg.

  • Roll Dimensions: 1200mm width x 40m length (providing a 48m² total material roll size).

  • Effective Coverage: 44m² per roll, optimized perfectly by a highly efficient 100mm longitudinal sheet overlap.

  • Engineering Grid Tolerances: Designed specifically for 367mm wire centres with a minimum 100mm overlap layout.

  • Mechanical Tensile Strength: MD 255 N/25mm | XD 160 N/25mm (providing superior cross-direction tear resistance).

  • Certified Thermal Resistance (R-Value): 1.55 m²K/W (officially tested and verified including standard roofing air gaps).
