Gilje

What Gilje does

Gilje is a Norwegian family-owned manufacturer of exterior windows and doors, founded in 1948 and headquartered in Stavanger, with production split between a window factory in Dirdal (Gilje Tre AS) and a door factory in Moi (Gilje Door AS). The portfolio centers on the premium eXtra line — Toppsving, Innadslående, and Fastkarm windows, and Ytterdør, Skyvedør, and Balkongdør external doors — built on timber cores with optional aluminum cladding, 3-layer glass, and U-values as low as 0.6, supplemented by an entry-level Basic line and the Klimanot slim-profile and Gilje Sense smart-home extensions. Specialty features include fire-rated (EI30/EI60), acoustic (up to 45 dB), solar-control, self-cleaning, and safety glass options, backed by 20–30 year warranties.

The company sells exclusively into the Norwegian market through a hybrid go-to-market: a nationwide authorized dealer network for local consultation and installation, a direct e-commerce store (nettbutikk), and a dedicated professional/trade channel (Gilje Proff with the Varden loyalty program) targeting builders and contractors. Revenue is generated one-time on a unit-pricing basis for custom-made (skreddersydde) products. Differentiation rests on the "100% Norwegian produced" heritage narrative, a dense stack of environmental certifications (Svanemerket, ECO-Product, Miljøfyrtårn, EPD, FSC) that unlocks BREEAM-NOR points for green-building projects, and the internally developed Flyt 2021 production system that compressed lead time from 15 days to 5 hours. Notable customers span healthcare, education, hospitality, and real estate, with project awards including the Arkitekturprisen 2019 and Innovasjonsprisen 2024.

Regional players

• Tiivi: Finnish manufacturer of energy-efficient windows and doors with a comparable focus on cold-climate thermal performance; competes in the same Nordic premium residential segment but primarily in Finland.
• Elitfönster: Swedish window manufacturer producing timber and timber/aluminum windows for the Swedish residential market; comparable product technology and energy-efficiency tier, with regional rather than direct Norwegian overlap.
• H-Fasader: Norwegian facade and window contractor/installer active in the Norwegian renovation and new-build market; comparable channel position and project exposure, though operating more as an installer than a manufacturer like Gilje.

Direct peers

• Outline Vinduer: Danish window manufacturer offering energy-efficient wood and wood/aluminum windows targeted at premium residential and passive-house segments in Scandinavia — overlapping Gilje eXtra's U-value and sustainability positioning.
• Velfac: Danish manufacturer of composite wood/aluminum windows and doors serving Scandinavian new-build and renovation projects; directly comparable in materials, U-value positioning, and architectural-project specification channel.
• Lian Trevarefabrikk: Long-established Norwegian window and door manufacturer based in Lyngdal, producing bespoke timber windows and exterior doors for the Norwegian market with a similar craftsmanship heritage and dealer-network distribution model.
• NorDan: Norwegian manufacturer of windows and exterior doors with a comparable product portfolio spanning timber and timber/aluminum-clad units, serving both residential and professional channels across Norway — Gilje's most direct domestic competitor.

Broad incumbents

• Velux: Danish global leader in roof windows and skylights with broader fenestration exposure; overlaps with Gilje in residential daylighting and energy-efficiency positioning, but operates at far greater scale and category breadth.
• Schüco: German global building envelope specialist offering aluminum and composite window/door systems; competes with Gilje at the architectural specification end of the Norwegian commercial and premium residential market.
• Internorm: Austrian pan-European manufacturer of high-end windows and doors (timber, timber/aluminum, uPVC) with a strong passive-house and energy-efficiency proposition; competes for premium Nordic projects but at broader geographic and portfolio scale.
