Description
AAC block market Germany: sales of aerated concrete blocks and forecast to 2031
How is the AAC block market in Germany developing? The dataset quantifies sales of autoclaved aerated concrete (AAC) precision blocks in million m³ of masonry for every quarter from Q1/2021 to Q4/2031, as historical market data and forecast.
The dataset covers load-bearing masonry made of steam-cured aerated concrete. The fine-pored structure makes the material light and highly insulating, allowing single-leaf external walls without extra insulation. As compressive strength is lower than for calcium silicate or brick, use centres on single- and two-family houses and low-rise buildings; in multi-storey housing AAC plays hardly any role. In non-residential buildings it serves light infill walls and small commercial units, in renovation extensions, added storeys and partitions. Brick, calcium silicate and lightweight blocks are separate datasets.
Demand follows owner-occupied housing, whose builders react particularly sensitively to rising interest rates and costs, so sales fell sharply in 2023 and 2024. Main competitors are backing bricks and, increasingly, timber construction; in apartment buildings calcium silicate prevails thanks to load capacity and acoustics. The insulating single-leaf wall keeps AAC attractive for energy-efficient building. After the 2024/2025 trough, a subdued recovery follows that does not reach pre-crisis levels by 2031, as single-family construction returns only slowly.
Which questions about the AAC block market does the dataset answer?
- How far did AAC sales fall in 2023 and 2024?
- When and how fast will demand for aerated concrete blocks recover by 2031?
- How is masonry volume split between residential and non-residential buildings?
- What volumes arise from extensions, added storeys and partitions compared with new build?
Who is the dataset for?
Relevant users are AAC producers, suppliers of lime, cement, quartz sand and aluminium powder, merchants, masonry house builders and planners. Investors and analysts gain a basis for capacity decisions and market models.
Data basis and methodology
Data are split by new build/renovation and residential/non-residential buildings, plus the total market. The model links completions, permits and renovation activity with parameters such as masonry volume per m² of floor area for thick single-leaf walls and the market share in owner-occupied housing; a shell-phase lead before completion is included. The model was cross-checked against available market and industry data as well as internal data.
Delivered as CSV and Excel files, each in German and English, with 44 quarterly values. Related datasets: Clay bricks, Lightweight concrete blocks (pumice, expanded clay), Timber frame elements (prefabricated) and all data on structural work, load-bearing structure and outdoor facilities.
