Wienerberger

What Wienerberger does

Wienerberger Oy Ab is the Finnish subsidiary of Vienna-listed Wienerberger AG, manufacturing and selling ceramic building materials — primarily facing bricks, brick slips, and the proprietary Poroton hollow block system — for residential, commercial, and public construction in Finland. The company's core technology is centered on Poroton perlite-insulated and open-cellular ceramic hollow blocks that meet Finnish insulation requirements (U-values of 0.14–0.17 W/m2K) without additional insulation layers, complemented by thin-joint mortar technology that enables rapid construction. Domestic production is concentrated at the Koria brick factory in Kouvola, with locally sourced clay and a 3.2 MW rooftop solar installation supporting ISO 50001-certified, climate-neutral production for select Poroton block lines since 2019.

The business operates a sales-led, multi-channel go-to-market model: direct enterprise sales to construction companies, contractors, and public sector clients; distribution through Finnish building material retailers (rautakaupat) for SMB and individual builders; direct e-commerce for chimney and fireplace products; and an architect/specifier engagement program anchored by physical showrooms in Helsinki and Kouvola, BIM/CAD design tools, and the biennial international Brick Award competition. Pricing is quote-based with no public list prices. Revenue is generated primarily through hardware sales of ceramic building materials, supplemented by imported products from the parent's European portfolio (e.g., Danish Egernsund bricks, hand-molded formats, URBAN facade cladding). The company holds 11–50 employees in Finland and is wholly owned by Wienerberger AG, a publicly listed parent operating in 35+ countries.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• CRH plc: Ireland-headquartered global building materials group with extensive European operations in aggregates, concrete, and masonry products. Broadly comparable as a major incumbent with overlapping product categories including masonry units and a Nordic presence competing for large construction projects.
• Wienerberger AG: The Austrian parent company and one of the world's largest producers of clay building materials. Directly comparable as the global operator of the same product categories (Poroton, Terca, Penter) that Wienerberger Oy sells in Finland, and the source of imported products distributed through the Finnish subsidiary.

Direct peers

• Röben Tonbaustoffe GmbH: German family-owned brick manufacturer producing facing bricks, clinker bricks, and ceramic building solutions. Direct comparable as a European producer of clay-based facade and structural products competing for specification in premium architectural projects.
• Forterra plc: UK brick and concrete products manufacturer producing facing bricks, brick specials, and masonry systems. Direct peer in product range and European market exposure, with comparable product lines for residential construction and facade applications.
• Rudus Oy: Finland's leading producer of concrete products, precast elements, aggregates, and concrete blocks. Direct competitor in the Finnish construction market, especially competing for structural wall and foundation applications where Wienerberger's Poroton hollow blocks face concrete alternatives.
• Ibstock plc: UK-based leading manufacturer of clay bricks and concrete building products. Direct comparable in product focus (facing bricks, brick slips, masonry systems) and in serving European residential and commercial construction markets with a similar sustainability positioning.
• Lujabetoni Oy: Finnish precast concrete and concrete element manufacturer. Direct competitor and partner in hybrid facade systems (e.g., Gräsantörmä project), competing for structural applications while increasingly combining with Wienerberger's brick slips in facade applications.
• Wiener Backstein (Egernsund Wienerberger): Danish facing brick producer now part of the Wienerberger Group, distributed through Wienerberger Oy's Finnish channel. Direct comparable in product range (wet-pressed facing bricks), though Danish-sized; serves as a reference point for Wienerberger's premium imported offering in Finland.

Emerging players

• Michelmersh Brick Holdings plc: UK-based premium brick manufacturer producing facing bricks, specials, and clay pavers. Comparable in product focus on premium facing bricks and facade products, though smaller scale; useful as a reference for premium brick positioning in residential and architectural projects.
• Paroc Group Oy: Finnish stone wool insulation manufacturer and historic competitor in building envelope solutions. Comparable as a Finnish-based building materials producer targeting energy efficiency, though Paroc's insulation-centric portfolio competes indirectly with Poroton's monolithic wall approach.
