Alufoil® FR Lite Domestic Grade (Double-Sided Thermal Barrier)

Alufoil® FR Lite Domestic Grade is a premium, double-sided thermal barrier insulation engineered specifically to balance heavy-duty protective performance with outstanding cost-efficiency. The membrane consists of a high-strength, multi-layered aluminium foil laminate that is structurally reinforced with a fibreglass scrim for exceptional tear and tensile resistance. Featuring highly advanced fire-retardant properties and pure aluminium foil on both sides, this domestic-grade solution is perfectly optimized for residential homes, light industrial buildings, housing developments, and commercial properties. It is built for seamless, fast installations, boasting a market-leading pace-to-area ratio that saves contractors significant time and on-site labor costs. Once installed, it requires zero maintenance, will not readily age, and is entirely non-hygroscopic—ensuring it never absorbs moisture, degrades over time, or promotes the growth of fungi, mould, bacteria, or vermin.

Versatile Structural Applications

  • Residential Trusses & Tiled Roofs: Installed horizontally across rafters or trusses from eaves to ridges, pulled perfectly taut, and secured with industrial staples directly before the tile brandering is fixed.

  • Commercial Over-Purlin Layouts: Laid smoothly over 1.6mm galvanised steel straining wires spaced at tight 367mm centres, using double-sided tape on the eave and apex purlins to lock the membrane down securely before roof sheeting is applied.

Problem-Solving Profile

  • Solves Compliance & Climate Control: Delivers a highly thermally efficient barrier that fully complies with SANS 10400XA energy efficiency regulations, driving down artificial heating and cooling bills.

  • Solves Commercial Fire Regulations: Incorporates top-tier fire retardants to secure the highest fire rating achievable for multi-layered aluminium foil insulation products, certified to SANS 10177 Part 5 & 10 (A/A3) and SANS 53501-1 (B-s1, d0).

  • Solves Dust & Darkness Infiltration: Functions as a permanent, non-deteriorating indoor dust barrier, while its ultra-low emissivity surface reflects light so efficiently that it instantly brightens up unceiled interior spaces.

Quick Technical Specs

  • Material Density & Weight: 180gsm material mass with an easy-to-handle roll weight of approximately 9kg.

  • Roll Dimensions: 1250mm width x 40m length (50m² total material roll size).

  • Effective Coverage: 44m² per roll, which safely accounts for the required 150mm structural overlap.

  • Engineering Grid Tolerances: Designed for 367mm wire centres with a minimum 150mm longitudinal sheet overlap.

  • Mechanical Tensile Strength: MD 255 N/25mm | XD 130 N/25mm.

  • Certified Thermal Resistance (R-Value): 1.64 m²K/W (officially tested and verified including standard roofing air gaps).
