Røros Dører og Vinduer AS

What Røros Dører og Vinduer AS does

Røros Dører og Vinduer AS is a privately held Norwegian manufacturer of premium exterior wooden windows and doors, headquartered and produced at Osloveien 38, NO-7374 Røros, Norway. The company traces its operating history to 1875 through its fusion with Sjøvold and is organized as an Aksjeselskap under organization number NO 976 982 576. Its 16 employees operate from a single production facility serving the Norwegian residential market, with the company's managing director Tor Lømo-Hansen overseeing a recent brand modernization that introduced a modern exterior door series.

The product portfolio centres on two families: doors (Paneldør Eksklusiv, Speildør Eksklusiv, Standard and Koblet Terrassedører, Skyvedør sliding doors using the Spilka Tango system, and Spesialdører custom builds) and windows (Røros Standard, Røros Koblet, Antikvarvinduet, Aluminiumsbekledd, Spesialvindu, and the newer Røroskitt single-frame traditional-look window). Core technology comprises pressure-impregnated laminated finger-jointed knot-free pine (SINTEF-recommended since 1979), Accoya acetylated wood for premium door frames and panel surfaces, and 2-layer or 3-layer energy glass with argon fill and warm spacers achieving U-values below 0.80. The company markets three glass/cladding upgrade tiers — Standard, Energi+, and Optimal — backed by 30-year (standard and Energi+) and 40-year (Optimal, aluminium-clad) warranties against fungus and rot.

The business is a make-to-order manufacturer with a standard 4-week factory lead time, generating hardware-sales revenue exclusively through Norway's leading building materials retailers (byggevareforhandlere). Pricing is quote-based through authorized dealers; published price lists exist but public pricing is not disclosed. Customer segments include Norwegian residential homeowners, cabin and holiday-home owners (particularly in mountain and coastal climates), and heritage/conservation projects (including work in the UNESCO-listed town of Røros). Key supply-side technology and materials partnerships include Accoya, Glassolutions, Sherwin-Williams (surface coatings), Spilka (hardware), and Stora Enso (timber), while the company participates in industry bodies Norske Trevarer and Norlamell, the Klimapartnere climate network, and a SINTEF-coordinated Røros-local mass-customization collaboration.

Core offering

Røros Dører og Vinduer AS manufactures handmade wooden windows and exterior doors in Røros, Norway, combining 1800s craftsmanship with modern production methods. The product portfolio spans panel doors, mirror doors, terrace doors, sliding doors, and standard/coupled/heritage/aluminium-clad windows, all built with pressure-impregnated pine and Accoya wood. Products are sold exclusively through Norway's leading building materials retailers (byggevareforhandlere) with a standard 4-week factory lead time.

Product overview

Røros Dører og Vinduer AS is a Norwegian manufacturer of exterior timber doors and windows for residential and holiday properties. The product portfolio centres on two core product families — doors (dører) and windows (vinduer) — spanning multiple product lines that share a common construction approach (pressure-impregnated pine, Accoya, energy glass, NCS colour system) but target different aesthetics and price points. The door range includes Paneldør Eksklusiv and Speildør Eksklusiv (traditional panel and mirror doors in Accoya), Røros Standard Terrassedør and Koblet Terrassedør (terrace/patio doors), Skyvedør (sliding doors using the Spilka Tango system), and fully custom Spesialdører. The window range spans Røros Standard Vindu (five opening types), Røros Koblet Vindu (double-frame coupled window), Antikvarvinduet (heritage window), Røros Aluminiumsbekledd Vindu (aluminium-clad, 40-year warranty), Røros Spesialvindu (custom dimensions), and Røroskitt (a new traditional-look non-coupled window). Add-on energy glass packages (Energi+ and Optimal) provide upgrade paths for better insulation. Products are offered with 2-layer or 3-layer energy glass, optional aluminium cladding, and a wide range of accessories (handles, hinges, bars, functional glass types).

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Schüco International: German premium building envelope specialist offering aluminium, uPVC and timber-aluminium windows and doors for high-end residential and commercial projects. Comparable premium fenestration positioning and strong focus on energy efficiency, but with a much broader product portfolio and global footprint.
• Andersen Corporation: Large US-based window and door manufacturer (wood, fibrex, aluminium-clad) serving residential replacement and newbuild. Comparable business model around long-warranty branded wood window/door products, but at mass-market scale and in a different geography.
• JELD-WEN Windows & Doors: Global, multi-material window and door manufacturer covering wood, composite and uPVC across residential and light commercial. Comparable product category, but operates at vastly greater scale and breadth than the niche Norwegian craft producer.

Emerging players

• Velfac: Danish wood-aluminium composite window and door brand (part of the DOVISTA group) serving Nordic residential renovation and newbuild. Comparable on energy-efficiency and Scandinavian design language, but with a different material mix (composite vs Røros's solid wood).
• Rationel (DOVIDA group): Danish manufacturer of premium wooden and timber-aluminium windows and doors for the Scandinavian residential renovation market. Comparable Nordic heritage renovation positioning, premium custom aesthetics, and energy-efficiency focus.

Direct peers

• NorDan: Norway-headquartered manufacturer of wood and wood-aluminium windows and doors for the Nordic and UK markets. Directly comparable to Røros on product category, customer base (residential, renovation, heritage) and dealer-led distribution, but operates at materially larger scale.
• Hasås Vinduer og Dører: Norwegian wooden window manufacturer based in Hordaland producing timber windows and doors for the residential and cabin market. Closely comparable niche heritage/quality wood window positioning and Norwegian dealer-led go-to-market.
• Internorm: Austrian premium manufacturer of wood, wood-aluminium and uPVC windows and doors for the European renovation market. Comparable on premium energy-efficient window positioning, U-value focus and heritage/aesthetic product lines, though broader geographically.
• Lian Trevarer: Norwegian manufacturer of wooden windows and doors sold through the building materials retail channel. Comparable craft-based custom wood window/door manufacturer serving Norwegian residential renovation and heritage projects.

Others

• Norske Trevarer: Industry association of ~300 independent Norwegian wood product companies producing windows, doors, stairs, kitchens and furniture. Røros Dører og Vinduer is a member. Relevant as an industry-association peer and channel/ecosystem enabler rather than a direct competitor.
