The adoption of SANS 53501-1 has brought much-needed clarity to the fire performance classification of thermal insulation products in South Africa. By replacing the older binary approach of simply classifying materials as combustible or non-combustible, the new standard provides a more detailed understanding of how insulation products behave when exposed to fire.

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.

Achieving a well-insulated, energy efficient building starts with understanding how insulation gaps occur and how to avoid them.

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.

Sonic Liner is a flexible glasswool insulation for HVAC ducts, designed with an acoustically permeable black woven glass-cloth facing. It delivers outstanding sound absorption, thermal efficiency, and low air friction, reducing noise, saving energy, and improving indoor comfort in commercial and residential buildings.

Aerolite® Soft Touch isn’t just ceiling insulation—it’s peace of mind. Engineered from non-combustible glasswool and bonded with an inert thermosetting resin, this soft, yellow fibreglass insulation is designed for performance, comfort, and safety. Backed by global standards, it’s the insulation choice homeowners and professionals can trust.
