What H+H does
H+H International A/S (Nasdaq Copenhagen: HH) is a Denmark-headquartered building materials manufacturer founded in 1909 that produces autoclaved aerated concrete (AAC/aircrete) blocks and calcium silicate units (CSU) for the European residential new-build segment. Its core technology is the aeration of concrete to produce lightweight, thermally insulating aircrete blocks alongside denser, load-bearing calcium silicate blocks valued for acoustic and structural performance; product features include natural CO2 absorption through carbonation, A1 fire resistance, thermal mass buffering, and acoustic insulation up to 52 dB. The company sells directly to builders, architects, and developers through wholly-owned country subsidiaries in Denmark, Germany, the UK, the Netherlands, Poland, Sweden, Switzerland, and the Czech Republic, supported by a network of regional offices and manufacturing plants consolidated through acquisitions in 2015, 2017, 2020, and 2021.
The business model is B2B manufacturing with one-time product sale revenue mechanics; pricing is negotiated through direct sales relationships and is not publicly disclosed. H+H earns revenue when construction professionals specify and purchase its blocks for new residential and commercial builds, serving ~500 families per day moving into homes built with H+H materials. The 2022 record year delivered 14% organic growth and DKK 455 million EBIT before special items, but the 2023-2025 cycle has seen European residential construction weakness prompt permanent closure of five plants, a 2023 business improvement program targeting plant network efficiency and SG&A savings, and an FY2025 outlook for near-flat organic revenue with EBIT compressed to DKK 85-115 million. An analyst estimate of DKK 2,638 million revenue for FY2026 anchors the current revenue base, with major shareholder Solbet Sp. z o.o. (25-32.99% of share capital) reflecting a strategic industrial anchor.

H+H product offering
Product offeringCore offering
H+H manufactures and sells wall-building materials — specifically aircrete (autoclaved aerated concrete) blocks and calcium silicate units — for use in residential new building construction across eight European markets. The products are sold directly to builders, architects, and developers, and are designed to provide fire resistance, thermal performance, acoustic insulation, moisture regulation, and CO2 absorption for modern house building.
Product overview
H+H International A/S operates as a building materials manufacturer offering two core product lines: aircrete blocks and calcium silicate units. Aircrete blocks are lightweight, highly insulating materials used in solid and cavity walls for residential and commercial construction. Calcium silicate blocks are dense, load-bearing units ideal for external walls and partitions where sound insulation and structural capacity are critical. Together, these products form H+H's core wall-building materials portfolio serving the residential new building segment across European markets.

H+H competitors and assessment
Company assessmentRegional players
- AERCON AAC: US-based autoclaved aerated concrete manufacturer serving North American residential and commercial construction. Geographically distinct from H+H but offers the same core AAC wall-building technology and serves similar use cases.
- Forterra plc: UK-listed manufacturer of building products including concrete blocks, bricks, and masonry solutions. Directly comparable as a UK-headquartered wall-building materials supplier serving residential construction with overlapping product categories such as concrete blocks.
- Bauroc International: Leading AAC block manufacturer in the Baltic states (Latvia, Lithuania, Estonia) and a growing presence in Northern Europe. Offers directly comparable aircrete wall-building products, although geographically focused on Baltic markets where H+H is less active.
- Thomas Armstrong (Holdings) Ltd: UK-based manufacturer of concrete blocks, aggregates, and wall-building products. Competes with H+H UK (Celcon) in the British residential market with directly overlapping concrete block offerings.
Broad incumbents
- Knauf Group: Global building materials leader in drywall, insulation, and plasterboard systems. A broad incumbent in residential wall-building envelopes that competes with H+H for interior wall specifications in Europe, particularly through Knauf Insulation and Knauf Gips.
- Boral Limited: Australia-headquartered building products and construction materials group with a global footprint including AAC operations (CSR Hebel). A broad incumbent in masonry and wall-building products, providing a comparable geographic and product diversification profile.
- Wienerberger AG: Vienna-listed global leader in clay bricks, roof tiles, and concrete pavers. A broad incumbent in European wall-building materials, competing with H+H for residential wall specifications though focused on clay-based rather than AAC products.
Direct peers
- Solbet Sp. z o.o. Polish AAC block manufacturer and H+H's largest shareholder (25–32.99% stake). Operates competing AAC plants in Poland and Central Europe, serving the same residential new building market with overlapping wall-building product portfolios.
- Xella International: Europe's largest manufacturer of autoclaved aerated concrete (AAC) products under the YTONG, Hebel, Multipor, and Silka brands. Directly competes with H+H across most European geographies and serves the same residential wall-building segment with comparable AAC and calcium silicate products.
Others
- Bauhaus AG (Building Materials): Major European home improvement and building materials retailer. Not a manufacturer, but as a downstream channel partner/customer for H+H wall-building products across its European store network, it is an ecosystem participant relevant to H+H's distribution strategy.
