Heavy-Duty Industrial Protection

Alufoil® FR White Heavy Industrial Grade is an advanced, heavy-duty thermal barrier roof insulation meticulously engineered for environments that demand maximum physical strength alongside a clean, premium aesthetic finish. This high-performance membrane is built from a multi-layered aluminium foil laminate, structurally reinforced with a fiberglass scrim to provide exceptional rigidity compared to traditional woven matt foil laminates. It features an innovative dual-surface design, incorporating a high-reflectivity aluminium foil layer on the reverse side to face the roof sheets, and a specialized clean white facing on the exposed side to transform the interior appearance of any facility. Designed for industrial, commercial, and residential buildings, its high pace-to-area installation methodology dramatically minimizes on-site labor time and project costs. It requires zero long-term maintenance, will not readily age, and is entirely non-hygroscopic—preventing the absorption of moisture and ensuring it never promotes or sustains fungi, mould, bacteria, or vermin.

Premium Structural Applications

  • Industrial Steel Over-Purlin Systems: Laid smoothly below the roof sheets over 1.6mm white PVC coated straining wires spaced at 367mm centres, with the first wire placed 50mm in from the gable end to maintain a flawless aesthetic match with the white ceiling layer. Sheets are given a strict 100mm overlap and temporarily held in place using GDA grade double-sided tape on the eave and apex purlins until the final roof sheeting is secured.

  • Truss & Tiled Roof Layouts: Run horizontally across rafters or trusses working from the eaves up to the ridges, overlapping each subsequent layer by a minimum of 100mm. The membrane is pulled perfectly taut and securely stapled using industrial-grade staples right before the tile brandering is permanently fixed.

Problem-Solving Profile

  • Solves Dim Interiors & High Lighting Costs: The specialized white finish dramatically increases interior light reflectance, instantly brightening unceiled facilities, workshops, showrooms, retail centers, or community halls while significantly cutting back on the need for artificial overhead lighting.

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

  • Solves Structural Sagging & Infiltration: Delivers heavy-duty tensile strength to keep the insulation flat and perfectly taut across wide commercial purlin grids, all while serving as a highly effective, permanent barrier against dust, vapour, and heavy atmospheric heat.

Quick Technical Specs

  • Material Density & Heavy Weight: High-density 251gsm material mass with a robust, ultra-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, calculated precisely to account for the required 100mm structural sheet overlap.

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

  • Mechanical Tensile Strength: MD 255 N/25mm | XD 160 N/25mm (delivering optimal cross-direction tear resistance under high tension).

  • Certified Thermal Resistance (R-Value): 1.19 m²K/W (officially tested and verified including standard roofing air gaps to comply with SANS 10400XA regulations).
