KLH Massivholz

What KLH Massivholz does

KLH Massivholz GmbH is an Austrian manufacturer of large-format Cross-Laminated Timber (CLT) elements, sold globally under the brand name "KLH® - CLT." Founded in 1997 (with the world's first CLT plant commissioned in 1999 at Katsch, Austria), the company produces structural wall, ceiling, and roof panels used in multi-story residential, commercial, public, and educational construction. Manufacturing is anchored in two Austrian facilities — the original plant at Teufenbach-Katsch and a second automated line at Bad St. Leonhard (opened 2019, ~125,000 m³ annual capacity) — with a third plant under construction at Wolfsberg (~150,000 m³ planned capacity, co-financed by the ERDF). Production uses CNC-controlled cutting for high dimensional accuracy, and operations are supported by an on-site rail siding and an 1,800 kWp photovoltaic system supplying most of the Wiesenau site's own power demand.

The company monetizes via project-based, custom-manufactured CLT sales (one-time license/project revenue), supplemented by the KLH designer digital platform — an all-in-one toolset comprising data+ (mechanical properties and fire scenarios), statics2D (beam analysis), and co2 (life-cycle carbon calculation) for architects, engineers, and construction professionals. Go-to-market is hybrid: a direct enterprise field-sales team with dedicated area managers covering DACH, Benelux/Middle East/Latin America, Eastern Europe/Baltic States, and Southeast Asia/Australia/New Zealand, complemented by a global network of distribution partners, industry-event presence (BuildNZ, ReThink HK, WCTE, Building Green, IHF, EBH), and reference-driven content marketing. Customer segments span residential, commercial/public, education, and cultural construction, with named reference projects in Denmark, Norway, the UK, the US, Poland, Australia, and New Zealand. Certification stack includes ETA-06/0138, CE marking, AITIM Quality Mark, Nordic Swan Ecolabel, EPD per ISO 14025/EN 15804, plus market-specific fire classifications (NRO in Poland, AS 1530:2014 in ANZ).

The firm is privately held, with three Managing Directors (Marco Huter, Johann Hochegger, Johann Gregor Offner) and a CTO, and reports no disclosed institutional investors or parent company. Wholly owned subsidiaries include KLH Massivholz Wiesenau GmbH (production entity) and KLH UK (regional sales).

• Mayr-Melnhof Holz: Austrian-based leading European manufacturer of CLT, glulam and engineered wood. Direct competitor in mass-timber panels for residential, commercial and multi-storey construction.
• Eugen Decker: German family-run CLT manufacturer producing cross-laminated timber panels. Direct comparable in product, customer profile (European developers/contractors) and custom project-based sales.
• Hasslacher Norica Timber: Austrian sawmill and engineered wood group with a dedicated CLT division. Competes with KLH in DACH and export markets on large-format cross-laminated timber.
• Stora Enso: Finnish-Swedic forest products major and one of the largest CLT manufacturers in Europe. Competes head-to-head with KLH on structural CLT panels across European and global projects.

Emerging players

• StructureCraft: Canadian engineered timber builder and CLT manufacturer focused on architecturally ambitious timber structures. Comparable on the bespoke CLT/mass-timber project model and on serving design-led commercial builds.

Regional players

• XLam: Australian/NZ CLT manufacturer serving the Australasian mass timber market. Comparable product and similar multi-storey/cultural reference portfolio, but operates as a regional alternative to KLH's exports into the same geography.
• B&K Structures: UK-based supplier of CLT, glulam and steel-timber hybrid structures. Comparable on product (CLT panels and engineered timber for UK/EU construction) and on serving architects for multi-storey timber buildings.
• SmartLam: North America's first and largest producer of CLT, focused on the US and Canadian markets. Comparable product (CLT panels for commercial and residential construction) but geographically separate from KLH's Austrian base.
