What STENI AS does
STENI AS is a privately held Norwegian manufacturer of fiberglass-reinforced stone composite facade panels, founded in 1965 and headquartered in Steinsholt, Norway. The company produces a portfolio of branded facade, roofing and foundation wall products — Steni Colour (80 standard colors), Steni Vision (printed/custom graphics), Steni Nature (natural stone, olivine and recycled glass surfaces), Steni Protego (roofing), and Terra by Steni (foundation walls) — plus a circular-economy line, Steni Colour Reuse. Since founding, the company has produced over 50 million m² of facade panels, documented by SINTEF at an expected 60-year service life and marketed with the longest functional warranty in the market (60 years). The technology platform centers on a proprietary fiberglass-reinforced stone composite that is 100% waterproof, frost-resistant to -30°C, impact-resistant, and bendable to a 3.5m radius, with carbon footprint documented at 14-17 kg CO2/m² under ISO 14025/ISO 21930/EN15804 EPD certification.
The business model is predominantly project-based hardware sales with quote-based pricing (no public list prices). STENI operates a dual go-to-market: direct enterprise field sales to architects, contractors and builders for commercial, educational and public-sector projects, complemented by a network of authorized building material distributors that handle the private/SMB market across Norway. The company also invests in self-serve digital channels — a 3D Design Generator (with Polytwin), a Price Calculator, BIM modules (on BIMobject), and an 8-language Installation Guide App (with Buildright) — to embed its products into the architectural specification workflow. Customer end-markets span educational buildings (primary), residential housing cooperatives (primary), commercial, and public infrastructure, with documented project wins across Norway, Sweden, Denmark and the Netherlands. Pricing is described as sometimes higher per square meter than alternatives but supported by lower total cost of ownership (3% installation waste vs. typical 13%, minimal maintenance, 60-year warranty).
The company is independently owned with no disclosed parent, institutional investors, or capital markets activity; there are no public revenue figures, no funding rounds, and no M&A history in the available data. Headcount is in the 101-250 band. STENI has received industry recognition including an OBOS Award (2017), a DOGA Award for circular-economy architecture, a Building Practice Award for Kongsvinger School, and BREEAM-NOR 'Excellent' certification for the Kilden Kindergarten reference project.
