Glasswool is considered to be the most effective, and environmentally friendly insulation product to use as it is non-combustible, and meets the requirements for optimal thermal and acoustic insulation performance.
Sagex is Isover's EPS division manufacturing a range of rigid polystyrene solutions.
Sagex EPS offers a choice of lightweight, high compressive strength and water resistant insulation solutions for use in industrial, commercial and domestic applications.
During National Water Week, Isover highlights the importance of responsible water management in water-stressed South Africa. The construction sector uses around 15% of global freshwater, making efficiency across the value chain critical. By implementing Step 0 water metering, Isover gained insight into water use within its manufacturing processes. This data helped identify leaks and optimise operations, resulting in a 65% reduction in water consumption from the original baseline.
Insulation in Gauteng is essential for comfort, energy savings, regulatory compliance, and fire safety. Meet SANS standards, improve EPC ratings, and reduce costs with high-performance building insulation.
South Africa’s adoption of SANS 53501-1 (replacing SANS 428) aligns local rules with EN 13501-1 Euroclass, rating insulation from A1 to F with s1–s3 and d0–d2 indicators. This shift adds nuance beyond the old A/B system, vital in homes with limited escape routes. Choosing non-combustible insulation like Isover glasswool (A1 or A2-s1,d0) offers zero fire spread, minimal smoke, and long-term safety. With SANS 53501-1 in place, selecting non-combustible materials is the smartest way to future-proof buildings.
In South Africa’s rapidly growing cities and towns, buildings are expected to deliver more than just shelter — they need to provide comfort, safety, and efficiency. One of the key contributors to achieving this is insulation.
