Lett-Tak

What Lett-Tak does

Lett-Tak Systemer AS is a Norwegian manufacturer specializing in the design, production, and installation of prefabricated roof elements for the Nordic construction market. Founded in 1980 in Larvik, Norway, the company operates four production lines with a combined capacity of 250,000 m² per year and has produced over 8 million m² of roof elements since inception. Its core product lines include Lett-Tak Classic, a steel-plywood composite roof element, and Lett-Tak Wood, an LVL-based engineered roof system introduced in 2023. The company has also developed E-TAK, an integrated energy roof product, and is extending into wall elements under the EasyBuild line, broadening its prefabricated building envelope offering. Lett-Tak's products hold European Technical Assessments (ETAs) and SINTEF technical approvals, and the company is certified to ISO 9001, 14001, and 45001 standards, supporting specification in regulated Nordic public tenders.

The company sells directly to construction industry clients on a project basis, with a customer base spanning large-scale sports and infrastructure venues (Friends Arena, Telenor Arena, Multisportarena Malmö), public buildings, and a distributed tail of 800+ schools across the Nordic region. Its geographic footprint covers Norway, Sweden, Denmark, and Finland, with logistics supported by a 2026 partnership with Bring for green distribution. The business operates on a B2B project-based revenue model with no recurring revenue, and large anchor projects create lumpiness in order flow. Lett-Tak has begun experimenting with AI through a beta chatbot called coreAI, which uses third-party AI services for website-based customer Q&A, but this is not yet a material operational capability. The company remains privately held with no disclosed funding rounds.

Core offering

Lett-Tak designs, produces, and installs custom-engineered prefabricated roof elements (Lett-Tak Classic and Lett-Tak Wood) for commercial, public, and large-scale buildings across the Nordics. Each project is delivered turnkey — from consultation and engineering through indoor prefabrication to on-site installation by the company's own crews — and includes complementary solutions such as solar-integrated energy roofs, green and blue roofs, and full service/aftermarket maintenance. The product portfolio covers spans up to 18 meters, U-values down to 0.075 W/m²K, and a CO₂ footprint as low as 22–24 kg CO₂ekv/m² for the Wood line.

Product overview

Lett-Tak Systemer AS offers a portfolio of prefabricated, custom-engineered roof element systems and related services spanning the full project lifecycle — from design and engineering through manufacturing, installation, and long-term service. The core product line consists of Lett-Tak Classic (steel-plywood composite elements, spans up to 18 m) and Lett-Tak Wood (wood-based LVL elements, spans up to 16 m, low CO₂ footprint). These are complemented by specialized add-on roof solutions including E-TAK (integrated solar + battery energy roof), solar panels, green roofs, blue roofs, and used/recycled elements. The EasyBuild system extends the concept to wall elements. Full-service delivery covers consultation, engineering design, production at Lett-Tak's Larvik facility (up to 250,000 m²/year), installation by Lett-Tak's own crews (up to 1,200 m²/day), and aftermarket services including annual maintenance contracts, condition reporting, and repair. The company also offers an AI-powered website chatbot called coreAI.

Broad incumbents

• Wienerberger: Large European producer of building materials (bricks, roof tiles, wall systems) including prefabricated wall and roof system solutions. Comparable as a broad incumbent offering integrated building envelope products across European markets.
• Kingspan: Global leader in insulated panels, roofing systems, and building envelopes. Overlaps with Lett-Tak on prefabricated insulated roof and wall elements, but at much greater scale and across a broader geographic footprint.

Others

• Ruukki: Nordic supplier of steel-based building products, including roofing and steel profiles, and an existing steel-profile supplier to Lett-Tak. Adjacent competitor in metal-based roofing and structural components, with overlapping Nordic customers.

Direct peers

• Plannja: Swedish/Nordic producer of metal roofing, sandwich panels, and profiled sheets for residential and commercial construction. Comparable to Lett-Tak on Nordic roofing materials and direct sales to contractors and developers.
• Moelven: Norwegian wood-based building products group producing engineered wood, glulam, and prefabricated structural elements for the Nordic market. Highly comparable on geography, customer base (contractors, building owners, public sector), and engineered-wood product portfolio.
