The Europe autoclaved aerated concrete (AAC) market size reached around USD 1.75 billion in 2024. The market is projected to grow at a CAGR of 5.50% between 2025 and 2034 to reach nearly USD 2.99 billion by 2034.

Europe Autoclaved Aerated Concrete (AAC) Market Growth

Autoclaved Aerated Concrete (AAC) is a green precast building material that offers insulation, structure, and fire protection. It is extensively deployed in Europe in the residential, commercial, and industrial construction. Due to its thermal insulation qualities, AAC can reduce heating and cooling requirements by up to 30%, which provides long term monetary benefits to homeowners.

Spain issued the highest number of licenses in Europe in 2022, despite challenges due to higher interest rates and building material prices. The number of licensed square metres expanded by 43.4% in 2022 compared to 2021. In the residential sector, building permits increased by 44.2%, while the non-residential building sector experienced a rise of 41.7%.

The growth in the number of licensed square metres for residential construction in Spain was driven by a strong demand for single-family homes during H1 2022 while the demand for new offices aided the growth of the non-residential sector.

Initiatives to reduce CO2 emissions associated with AAC use

The European Autoclaved Aerated Concrete Association (EAACA)'s NetZero Roadmap is helping the AAC sector reach net-zero emissions by 2050. The key levers, such as the use of low carbon cement and lime, renewable energy sources, low emissions transport, reusing and recycling AAC, and recarbonation are expected to reduce the carbon emissions of AAC products from 180 kg to -70 kg of CO2e per m3 by 2050, increasing their sustainability.

Surge in renovation activities

The EU's building sector is responsible for 40% of energy consumption and 36% of total GHG emissions. Under the EU's Renovation Wave strategy, the government aims to enhance the energy efficiency of its buildings. This will increase the demand for AAC insulation products due to their superior thermal insulation properties and support the Europe autoclaved aerated concrete (AAC) market expansion.

Growing adoption of green building designs

AAC is the preferred walling material for LEED-certified buildings and is a 100% green building material. There is a growing demand for green buildings in the EU among commercial customers who are willing to pay a premium to lease them. For instance, in London, the average rental premium for green-certified offices is over 11%.

AAC blocks display robust properties over clay bricks and concrete

AAC blocks are around 3-4 times lighter than red bricks, making them economical and easy to transport. There is a greater strength-to-weight ratio with AAC blocks. This reduces the number of blocks needed per square metre and provides monetary benefits. Further, AAC blocks result in reduced structural costs as it saves steel use by up to 15%.

Europe Autoclaved Aerated Concrete (AAC) Market Trends

AAC products are widely used in the EU. It is used in over 40% of construction projects in the UK and 60% in Germany. AAC is made from natural ingredients, does not contain any chemicals or volatile compounds, and emits no pollutants by-products during manufacturing. This makes it a healthy, safe, and 100% sustainable building material. It is a walling material of choice for LEED-certified buildings. AAC products also enhance the indoor air quality of structures.

In 2022, around 40 million Europeans were unable to afford energy to heat their homes. The EU's Renovation Wave strategy launched in October 2020 as part of the Green Deal, aims at renovating 35 million buildings by 2030 to improve their energy efficiency. The European Green Deal is viewed by the AAC market as an opportunity for growth that provides it a competitive edge over other building materials due to its sustainability benefits. AAC is a 100% recyclable material, making it an ideal solution to meet the needs of circularity and reduce GHG emissions.

Europe Autoclaved Aerated Concrete (AAC) Market Share

Based on element, blocks account for a significant share of the market

AAC blocks are known to be half the weight and ten times the size of traditional bricks. This makes it suitable for simple installation and offers the required flexibility, cutting, shaping, etc. AAC blocks are soundproof due to their lightweight and porous characteristics. Hence, it is being widely used across hospitals, schools, studios across the region.

AAC floor elements, on the other hand, are known for their combination of strength, thermal, and acoustic insulation. The adoption of AAC floor elements provides the features of concrete floors at significantly lower cost and with better insulation values.

Meanwhile, AAC industrial wall panels can be used as both internal load-bearing structure or an outer wall. The panels are medium/heavily reinforced allowing them to hold the weight of multiple-story buildings. The presence of high precision on thickness makes them suitable for double-sided applications.

Based on end use, the residential sector significantly contributes to the Europe autoclaved aerated concrete (AAC) market revenue

Autoclaved aerated concrete (AAC) is adopted as masonry blocks and prefabricated reinforced elements majorly in residential buildings. AAC blocks are being used as exterior walls in residential projects. The significant importance of fireproof houses is catering to an increased adoption of AAC panels on roofs to protect the structure from the flying embers that ignite house fires. By 2026, it is estimated that Europe will have finished constructing about 1.5 million housing units.
