What KLH UK does
KLH UK Limited is the UK sales, technical advisory, and specification subsidiary of Austrian CLT pioneer KLH Massivholz GmbH. Founded in 1999 in Katsch, Austria, where it built the world's first cross-laminated timber manufacturing facility, KLH now operates two Austrian production sites with combined annual capacity of approximately 125,000 m³. KLH UK operates from 23 Jacob Street in London with a small enterprise sales team focused on project enquiries, technical consultation, and lead generation for the parent's panel production.
The company's product stack centers on KLH® - CLT solid wood panels (cross-laminated spruce boards bonded with PU adhesive, CNC-cut for dimensional accuracy, optionally using Loctite HB X adhesive for fire performance). Complementary digital and engineering assets include the KLHdesigner platform (data+, statics2D, co2 modules), Revit/AutoCAD BIM libraries, Dlubal RFEM stiffness property files, an extended Component Catalogue, and Environmental Product Declarations under ISO 14025 / EN 15804. Production is supported by a 1,800 kW peak photovoltaic system at the Wiesenau site. The portfolio is certified across UK (UKCA, UKTA, CHAS, Cyber Essentials, ISO 9001/14001), European (ETA-06/0138, CE), and international (AS 1530:2014, NRO/Poland, FSC, PEFC) frameworks.
KLH UK generates revenue through quote-based project sales of CLT panels to UK-based architects, developers, contractors, and public-sector clients across education (William Perkin C of E School, Mayfield School, Bowdoin College), residential (all.in99, Pallars), commercial (INSPIRE La Défense), and public/heritage (Hastings Pier) segments. Distribution is direct enterprise field sales via email and phone channels; pricing is custom per project and not publicly disclosed. The parent sells into 11+ countries (UK, Austria, France, Germany, Denmark, Norway, Romania, USA, Australia, New Zealand, Poland), and KLH UK participates in a global trade-show circuit (SHK, BuildNZ, ReThink HK, Mass Timber+, EBH, Building Green, IHF, WCTE). The company is privately held by KLH Massivholz GmbH with no venture capital or public shareholders indicated.
