What JUWO Poroton does

JUWO Poroton (legal entity: JUWÖ Poroton-Werke Ernst Jungk und Sohn GmbH) is a family-owned German manufacturer of high-performance ceramic bricks (Planziegel) for monolithic building envelopes, founded in 1862 and headquartered in Wöllstein, Rheinland-Pfalz. The company operates two production facilities — the main Wöllstein plant and the affiliated Adolf Zeller GmbH & Co. Poroton-Ziegelwerke KG plant in Alzenau — producing calibrated, thin-bed-mortar bricks across the ThermoPlan RX series (patented PoroTec® insulation filling, thermal conductivity down to 0.060 W/(mK)), the MZ/TV series (mineral wool filling), the S/SL series (100% ceramic, unfilled), and the T/TS series for standard applications. Performance specifications include U-values from 0.11 W/m²K enabling Passivhaus standards from 42.5 cm wall thickness, fire resistance up to F 90-AB, sound insulation up to 50.7 dB, and compressive strength up to fk 5.0 MN/m² for multi-story construction.

The company sells exclusively through the German building materials trade (Baustoffhandel) channel, supplemented by a dedicated field sales and project management team covering five German sales territories plus international markets (Benelux, UK, Ireland, France, Luxembourg, Denmark, Poland, and additional export markets) via country-level distributors and the JUWO Benelux regional office in Voerendaal. Revenue is generated through one-time product sales with no subscription component; pricing is communicated through dealer-only price lists with an internal discount system. End-customer demand spans private single-family home builders, multi-story residential developers, architects/specifiers (served through technical consulting and seminars), and large project developers (served through a dedicated project management team). The company also offers downstream services including the JUWÖ Festpreishaus fixed-price house concept and a digital Ziegel-Konfigurator for product selection. Certifications include CE, UKCA (first German clay block producer registered with BBA), BENOR, Güteschutz Ziegel, Eco Institut, ISO 9001, and ISO 50001.

Product overview

JUWO Poroton is a German brick manufacturer producing high-thermal-insulation plan bricks for monolithic construction. The product portfolio centers on four main brick series with different insulation technologies: the flagship RX-Serie (with patented PoroTec filling achieving up to 0.06 W/mK thermal conductivity), the MZ-Serie and TV-Serie (with mineral wool filling from stone or glass wool), the S- and SL-Serie (100% ceramic without filling for economic solutions), and the T-/TS-Serie (standard plan bricks for various applications). Accessories include thin-bed mortars (Maxit Therm 825, Mur 900), sound insulation products (SSL), and the JUWÖ-Klinkerriemchen-System for facade finishes. The company also serves the Netherlands and Belgium with the ThermoPlan TP calibrated adhesive block system, and offers the JUWÖ Festpreishaus fixed-price house concept. JUWÖ sells exclusively through building material dealers.

Direct peers

• Feldhaus Klinker: German family-owned clinker brick manufacturer focused on facing and façade applications. Comparable to JUWO's Klinkerriemchen accessory line and competes in the high-end German residential façade segment.
• Hagemeister GmbH & Co. KG: German family-owned clinker brick producer serving German and European façade markets. Directly comparable as a German Mittelstand brick specialist competing in similar residential and architectural segments.
• ABC-Klinker Group: German manufacturer of clinker bricks and ceramic façade products with multiple plants in Germany. Adjacent but directly comparable competitor in the German residential and commercial brick façade market.
• Wienerberger AG: Austria-headquartered, the largest European producer of clay blocks (Porotherm) and ceramic facing bricks. Directly comparable to JUWO Poroton in product category, target market (residential construction), and geographic reach across Germany, Benelux, UK and Central/Eastern Europe.
• Leipfinger-Bader: German family-owned clay block and brick manufacturer serving monolithic residential construction. Competes with JUWO in southern Germany and offers comparable high-insulation filled brick systems.
• Röben Tonbaustoffe: German family-owned producer of facing bricks, clay blocks, and clinker products. Directly comparable to JUWO's S/SL and T/TS series and competes for both structural and architectural brick applications in Germany and Europe.
• Schlagmann Poroton: German family-owned clay block manufacturer (Bayerische Ziegelwerke), operating plants in Bavaria and producing Poroton-branded high-thermal-insulation bricks. Closest German-headquartered competitor to JUWO with overlapping RX-equivalent high-performance product lines.

Broad incumbents

• Saint-Gobain SA: French multinational with broad building materials portfolio including clay bricks (Imerys/SEB), ETICS, glass and insulation systems. Competes indirectly with JUWO via multi-system dealer channels but does not specialize in the German monolithic brick niche.
• CRH plc: Irish-listed building materials group with European aggregates, concrete, and brick operations (e.g., Heidelberg-based BMTI). Overlaps with JUWO at the broad construction-materials level but does not directly compete in the German high-insulation monolithic brick niche.

Regional players

• Heluz cihlářský průmysl: Czech clay block manufacturer active across Central Europe. Comparable product range (filled high-insulation bricks) but focused on Czech, Slovak, Austrian and German-adjacent markets rather than direct head-to-head competition with JUWO in Germany.
