Starlite® Insulation consists of lightweight, high-quality, non-combustible glasswool rolls engineered with an inert thermosetting binder to deliver exceptional thermal efficiency, strength, and physical resilience. Specially optimized for industrial, commercial, and steel roof applications, Starlite® is available with a variety of robust, scrim-reinforced facings—including foil, white, or black coatings—to suit any interior design aesthetic. With a versatile operational threshold that safely handles working temperatures up to 230 °C, this eco-friendly “green” solution contains zero CFCs or HCFCs and is manufactured completely without blowing agents, ensuring zero Ozone Depleting Potential (ODP) and zero Global Warming Potential (GWP). It requires no long-term maintenance, resists aging for an exceptional product lifespan, and provides one of the most competitive comfort-to-cost ratios available on the commercial market.

Versatile Structural Applications

• Industrial Over-Purlin Layouts: Custom manufactured to requested building lengths and laid directly over-purlin immediately beneath the roof sheeting for seamless, comprehensive thermal protection.

• Steel Roof & Side Cladding Systems: Engineered to provide high-performance thermal and acoustic isolation within the roofs and side cladding of all types of commercial, public, and industrial facilities.

• Tensioned Wire Grid Configurations: Installed smoothly over galvanized or PVC-coated steel straining wires spaced at precise 300mm centres, featuring integrated longitudinal edge flaps that are pulled tight, stapled, folded back, and securely stapled a second time to guarantee airtight, vapor-sealed joints.

Problem-Solving Profile

• Solves Severe Noise & Sound Transmittance: Features excellent acoustic absorption properties, achieving a certified Noise Reduction Coefficient (NRC-Value) of 0.70 at just 50mm thickness to drastically dampen heavy rain, hail, and environmental drumming noises on large metal roofs.

• Solves Top-Tier Fire Compliance: Achieves the ultimate fire safety standard as one of the few South African insulation materials with a completely non-combustible glassfibre composition. It is officially certified under SANS 53501-1 with an A2-s1, d0 classification across all foil, white, and black facings, meaning it is legally approved for use in all single and multi-level structures spanning building occupancy classes A1 through J1.

• Solves Moisture, Corrosion, & Degradation: Formulated as an inorganic, chemically inert mineral material that will never cause or accelerate the corrosion of copper, steel, stainless steel, or aluminium. The non-hygroscopic fibers prevent condensation buildup in high-humidity applications and refuse to breed or sustain vermin, fungi, mould, or bacteria.
