Indu Light

What Indu Light does

INDU LIGHT Produktion & Vertrieb GmbH, trading as Indu Light, is a German family-owned manufacturer of daylight, natural ventilation, and smoke and heat exhaust (RWA) systems for flat-roofed industrial, commercial and public buildings. Founded in 1986 and headquartered in Halle (Saale), the company operates a fully integrated production stack from aluminum profile to assembled system, with in-house planning, manufacturing, assembly and maintenance functions. The product portfolio comprises five light-band families (Topline ELS, Proline, Skyline, Shedline with optional PV integration, Sideline), the Glasline post-and-rail glass roof system, light domes (Libra) and flat roof windows (Stella) including round variants, an integrated RWA and ventilation module set (Vela, Musca, Draco, Lyra, Virgo, Hydra, Taurus, Apus), and a Zubehör accessory line covering hail, fall, sun and insect protection, control technology and sound attenuation.

The company distributes exclusively within Germany through three directly operated regional sales entities (South/Deilingen manufacturing, East/Halle and West/Coesfeld via INDU LIGHT West Vertrieb GmbH) supported by a trade-partner channel of roofers, carpenters, specialist trade, general contractors and hall builders. Revenue is generated primarily from project-based one-time product sales of daylight and RWA systems for new construction and renovation, complemented by installation/assembly services, engineering/calculation services, RWA maintenance contracts and a subsidy-advisory service (Fördermittelauskunft). The customer mix spans commercial enterprises, public-sector clients (schools, transit, administrative buildings), architects and planners, contractors, facility managers, and SMBs across industrial, sports, retail, cultural and transport-infrastructure segments, as evidenced by a reference book spanning names such as Wagenhallen Stuttgart, Europahalle Karlsruhe, Erzgebirgsbahn Chemnitz and a family bakery in Aachen.

Indu Light occupies a specialist niche in the German flat-roof daylight market, leveraging 40+ years of operating history, the in-house fabrication of security-relevant RWA and ventilation components (including EN 12101-2 tested Libra NRWG), and integrated photovoltaic options (Shedline PV) to compete against larger general building-envelope players. The firm is privately held with no disclosed institutional investors or parent company, and no public filings, funding rounds or M&A are recorded in the available data.

INDU LIGHT manufactures and supplies daylight, ventilation, and smoke and heat extraction (RWA) systems for flat roofs, including light bands (Topline ELS, Proline, Skyline, Shedline, Sideline), the Glasline post-and-rail glass roof system, light domes and flat roof windows (Libra, Stella), and integrated RWA/ventilation components. The company delivers complete project solutions covering individual planning, precision manufacturing, professional assembly, and ongoing maintenance for new construction and renovation of industrial, commercial, and public buildings.

Product overview

Indu Light offers a comprehensive portfolio of daylight, ventilation, and smoke/heat exhaust ventilation (RWA) systems specifically designed for flat roofs.

These core daylight systems are complemented by integrated RWA und Lüftung (smoke exhaust and ventilation) solutions including ventilation flaps, louvered ventilators, multi-purpose ventilators, and mechanical smoke exhaust systems. Additionally, a full range of Zubehör (accessories) including hail protection, fall protection, sun shading, insect protection, control technology, and sound absorption provides complete system coverage. The company provides everything from individual planning through precision manufacturing, professional installation, and ongoing maintenance — positioning as a single-source provider for flat roof daylight and ventilation solutions in industrial, commercial, and public building applications.

Broad incumbents

• Velux Group: Global leader in roof windows and skylights with a much broader residential and commercial portfolio. While primarily residential, Velux Commercial overlaps with INDU LIGHT in flat-roof daylighting for institutional and commercial projects.
• Roto Frank Fenster- und Türtechnologie: Major German manufacturer of roof windows and hardware with a broader residential tilt. Comparable in flat roof window category (Stella at INDU LIGHT competes with Roto's flat roof offerings), but Roto's portfolio and scale extend far beyond this niche.

Direct peers

• Coxdome (Cox Building Products): UK-based manufacturer of rooflights, domes and flat roof glazing systems. Directly comparable product set to INDU LIGHT's Libra and Stella lines, though focused on the UK and Irish markets rather than Germany.
• LAMILUX Heinrich Strunz GmbH: German manufacturer of Lichtkuppeln, Lichtbänder, flat roof windows and RWA/smoke ventilation systems for industrial and commercial buildings. Closest direct competitor to INDU LIGHT with very similar product taxonomy and German market focus.
• JET Brakel Aero (formerly Jet Brakel): Manufacturer of natural daylight and smoke/heat extraction systems for industrial flat-roof buildings. Strong overlap with INDU LIGHT's RWA wings, louvered ventilators and light band product families across the German and Benelux markets.
• Kingspan Light + Air: Pan-European daylight and smoke/heat extraction specialist formed from Kingspan's acquisition of Colt International and Jet Group. Competes head-to-head in NRWG-certified RWA ventilators and glass roof systems for industrial and public buildings.
• ESSMANN Gebäudetechnik GmbH: German RWA and natural ventilation specialist serving industrial, commercial and public buildings. Overlapping product lines in NRWG ventilators, light bands and integrated control technology make it a direct peer in the German-speaking market.

Regional players

• Wasco Skylights: US manufacturer of custom skylights and flat roof daylighting systems. Product technology is comparable to INDU LIGHT's light dome and flat roof window offerings, though Wasco primarily serves North American rather than European markets.
