According to the Worldwide AAC (2019), the use of Autoclaved Aerated Concrete can contribute to a 40% reduction in energy consumption, making it an essential material for sustainable construction. In the case of single-family houses in Germany, architects often choose a AAC’s as exterior walls for reasons of architectural design, durability, and resistance against wind-driven rain penetration. In fact, AAC masonry with low thermal conductivity (λ ≤ 0.120 W/(mK)) makes it possible to meet ambitious energy efficiency requirements.

LightStrong AAC blocks offer superior thermal insulation, reducing the need for excessive heating or cooling in buildings. Their aerated structure minimizes heat transfer, keeping indoor temperatures stable despite fluctuating outdoor conditions. This translates to lower electricity consumption, reduced reliance on HVAC systems, and ultimately, a significant decrease in carbon emissions.
