What Thermory does

Thermory AS is an Estonian-headquartered (Tallinn) manufacturer of thermally modified wood (thermowood) and sauna materials, founded in 1997 and operating production facilities in Reola and Loo (Estonia) and Teuva (Finland). The company's core technology is a chemical-free thermal modification process that uses only heat and steam to produce durable, dimensionally stable, and climate-resistant wood products across species including ash, pine, spruce, radiata pine, oak, magnolia, aspen, and alder. Product surface treatments span thermally modified, natural, oiled, waxed, coated, brushed, embossed, roughened, and fire-protected finishes. The portfolio is organized into eight collections (Benchmark, SmartS, Shingles, Kodiak, Ignite, Vivid, Stripes, Drift) covering exterior cladding, decking, posts and beams, interior wall panels and flooring, and a complete sauna range including ready-made elements, doors, and windows. Proprietary installation systems (PaCS clip-strip, end-matching joints, QuickDeck modules, Herringbone modules) reduce installer labor and waste.

Thermory sells exclusively through an authorized distributor network spanning 60+ countries on all continents and does not transact directly with private customers. Distribution is supported by technical documentation, BIM resources, an insider portal, regional partners (Moelven, Carpentier Hardwood Solutions, Woodmaster, McCormacks Australia, Komplex Market, among others), and a flagship annual Thermory Design Awards competition launched in 2022 that builds architectural community engagement. The company targets architects, designers, contractors, real estate developers, and specialized wholesale distributors, with named flagship projects including Snohetta's Powerhouse Telemark, Kengo Kuma's Centro Arte Moderna Gulbenkian, and ZGF Architects' Baltimore Ravens Under Armour Performance Center.

Revenue derives from one-time unit sales of products and custom quotations (valid 30 days), with 50% prepayment required for custom orders above EUR 1,000 and FCA Incoterms 2020 delivery from the three production sites. The Thermory Group includes the Auroom premium wellness and sauna sub-brand and the Siparila Finnish wood products brand, and the company is EU Deforestation Regulation (EUDR) compliant. Leadership: CEO Simmo Soomets. The company is privately held with no disclosed external investors.

Scale indicators4 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Stora Enso: One of the largest private forest products companies in the world, with a broad portfolio including sawn timber, wood-based panels, and engineered wood for construction. Competes with Thermory at the high level of sustainable wood building products, though Stora Enso's offering is much broader and not specialty in thermal modification.
• UPM: Finnish forest products conglomerate producing plywood, sawn timber, and engineered wood products for construction. Overlaps with Thermory in sustainable wood building materials but at a vastly larger scale and broader product portfolio, headquartered in the same Finnish ecosystem.
• Metsä Wood: Part of Metsä Group, Metsä Wood produces engineered wood products including Kerto LVL and birch plywood for construction. A broad incumbent in the European engineered wood market, offering overlapping structural and panel products that intersect with Thermory's posts & beams and cladding ranges.
• West Fraser Timber: Large North American lumber, panel, and engineered wood products manufacturer. While primarily serving commodity and structural wood markets, West Fraser's engineered wood division competes in adjacent architectural and construction segments that overlap with Thermory's product space.

Regional players

• Novawood: Turkish producer of thermally modified wood for exterior and interior applications, including cladding, decking, and sauna materials. Overlaps with Thermory in product category but focuses on Turkey, Middle East, and select export markets.
• Tantimber: Polish manufacturer of thermally modified wood for facade, decking, and interior applications. Comparable in product offering to Thermory, serving a primarily Central/Eastern European market with limited global distribution compared to Thermory's 60+ country reach.

Emerging players

• Arbor Wood: North American thermally modified wood producer focused on exterior siding, decking, and dimensional lumber. Targets similar architectural and contractor segments as Thermory but with a primarily regional presence, making it a partial overlap peer rather than a direct global competitor.

Direct peers

• Kebony: Kebony produces furfurylated modified wood for exterior and interior applications, including decking and cladding. Competes directly with Thermory in the architectural specification market for sustainable, durable wood alternatives.
• Lunawood: Finnish producer of thermally modified wood (Thermowood) for cladding, decking, and sauna applications. Headquartered in Finland like Thermory's Teuva facility, and competes in the same Nordic thermowood category with overlapping distributor and customer bases.
• Accsys (Accoya): Accsys plc produces Accoya, an acetylated modified wood used for cladding, decking, and structural applications. It is the closest direct competitor to Thermory in the high-performance modified-wood category, competing for the same architectural specifications with a different (chemical) modification process.
