Aertec AAC goes up roughly three times faster than conventional brick — same wall, less wait, and the rest of the programme starts on time.
AAC is highly insulating and fire resistant which reduces energy costs by up to 30% compared with conventional masonry. Your building will naturally be warmer in winter and cooler in summer due to Aertec AAC's superior R-Values. AAC is also eligible for EDGE funding from financial institutions.
Heavier walling means deeper foundations, heavier structural frames, and more finishing material. AAC's lower dead load reduces all three — and on the 4 on Nursery 6-storey project, that translated to a verified 21% total project cost saving. Named. Measured. On the record.
"I ordered product from Aertec for one of my projects and received great service. The order was on time and I was kept up to date through clear communication. The product was on specification when it arrived and I received great technical support from Aertec during the design and installation phases of the project. My structural engineer was also impressed by the unique technology in the product, great cost effective weight saving opportunities without compromising quality! Looking forward to having them on board for future projects."
AAC lays 3× faster than conventional brick or block. Larger format, lighter weight, 3 mm thin-bed joints — the walls are done before they become the critical path, and every trade that follows can start on time.
AAC weighs a fraction of clay brick or concrete block. Lower dead loads let your structural engineer size down frames, foundations, and reinforcing — and every kilogram you remove from the structure reduces what you spend to support it.
7.5× more thermally insulated than clay brick, 12.5× more than concrete brick. Cooler in summer, warmer in winter, and up to 30% off HVAC running cost over the life of the building.
AAC's cellular structure is highly sound-absorbent — airborne noise between rooms and from outside drops audibly. The reason it shows up on residential, student, and hospitality specs.
Non-combustible with a fire rating well above conventional brick, block and drywall. Aertec AAC does not contribute to fire spread in line with SANS 51996-1-2 fire design requirements, without supplementary materials for fire protection.
11 kg CO₂/m² in manufacture, vs 129 kg for clay brick. Made from abundant natural raw materials, whereby 1m3 of dry materials yields 3m3 of finished AAC. AAC is internationally recognised by green-rated accreditation bodies.

This 6-storey residential development in Cape Town's Southern Suburbs specified AAC for all internal walls and the inner skin of the external hybrid cavity wall system — chosen for its weight reduction and verified cost performance.
AAC reduced the total dead load on the structure, allowing the engineer to size down foundations, columns, and slabs. Against a conventional masonry build, the project recorded the figures shown — named savings, on a named project, signed off by the structural team.
