What M SORA does
M SORA d.d., trgovina in proizvodnja, d.d. is a Slovenian joint-stock manufacturer of custom-made wooden and wood-aluminum windows, entrance doors, panoramic sliding walls, and fixed glazing systems, headquartered and producing from Žiri, Slovenia. Founded in 1948, the company operates a 105+-employee Window Architecture division and sells two core product families — Lesena okna (wooden windows) and Les-alu okna (wood-aluminum windows) — using locally sourced wood species (spruce, larch, oak, thermally modified spruce, meranti, Red grandis), glued laminated timber, and multi-layer coating systems. Named sub-brands include Udobje 3QL (85 mm profile, Uw 0.84–1.00 W/m²K) and Udobje Optimo XLS (95 mm profile, Uw 0.78–0.95 W/m²K), both Passive House Institute certified, plus the 2026-launched Lumnia line (narrow profile, flush alignment, highest ift Rosenheim air tightness class 4 and water tightness class 9A).
The company runs a project-driven, quote-based sales model through retail showrooms in Žiri and Ljubljana, an online inquiry channel, and a dedicated architect partnership portal; services span consultation, measurement, custom manufacturing, RAL-compliant installation, and annual preventive maintenance that extends warranty by two years. Distribution is primarily direct domestically, with the wholly-owned Norica business unit handling regional expansion through subsidiaries in Kosovo, Albania, North Macedonia, and Croatia, and named export partners (Maisons Chicoine Homes, Stich Consulting & Design) serving Canadian projects in cold climates. Operations are CE-marked under EN 14351-1 with Declarations of Performance on file, and the firm is led by General Director dr. Aleš Ugovšek.
Revenue is not publicly disclosed; no external parent or private equity ownership is evidenced, and shares are held by private shareholders (a 20th regular shareholders' meeting was held in June 2026). The product mix is firmly anchored in custom, premium, certified energy-efficient fenestration rather than mass-market stock windows, with customer concentration split between a long tail of Slovenian residential homeowners and a small set of recurring enterprise partners.

M SORA competitors and assessment
Company assessmentBroad incumbents
- VKR Holding (VELUX): Danish owner of VELUX roof windows and other building envelope brands. Adjacent building-envelope player rather than direct wall-window competitor, but comparable premium window manufacturer serving residential construction in Europe.
- Schüco: German global leader in aluminum window, curtain wall and façade systems plus uPVC windows. Competes with M Sora in high-performance building envelope but at much broader scale and with a metal-leaning product mix.
- Salamander Industrie-Produkte: German window and door systems group producing uPVC profiles and branded finished windows. Competes in adjacent performance segments to M Sora across Germany and broader Europe.
- REHAU Windows: Global polymer and building solutions group with a uPVC window systems business serving fabricators across Europe. Provides windows competing in adjacent performance tiers rather than bespoke wood, but competes for the same architectural specification slots.
Direct peers
- Gaulhofer Industrie Holding: Austrian window specialist producing wooden, wood-aluminum and aluminum windows with focus on energy efficiency and custom dimensions. Comparable regional positioning and target customers to M Sora.
- Josko Fenster: Austrian manufacturer of wooden, wood-aluminum and aluminum windows and entrance doors, with comparable mix of custom manufacturing, passive-house positioning, and an established DACH market presence. Directly comparable product portfolio and end-customers (homeowners and architects) to M Sora.
- Finstral: South Tyrolean manufacturer of windows, entrance doors and fixed glazing in PVC, wood-PVC and aluminum, with strong passive-house credentials. Closely mirrors M Sora's wood-aluminum emphasis and architectural specification strategy across Italy and adjacent Alpine markets.
- Internorm: Austrian premium window manufacturer covering wood-aluminum and aluminum systems with PHI-certified performance, multi-country distribution and architect/specifier channels. Highly comparable premium positioning, though at significantly larger European scale than M Sora.
Regional players
- Aluprof S.A. Polish-based aluminum systems manufacturer for windows, doors and façades with strong Central and Eastern European distribution. Comparable in regional window market presence but with aluminum rather than wooden product emphasis.
Others
