Skylux

What Skylux does

Skylux is an independent Belgian family-owned manufacturer of daylight and outdoor living solutions for flat roofs, in continuous operation since 1954 and headquartered in Stasegem, Belgium. Its product portfolio is organized around two pillars: roof windows (plastic dome skylights available in more than 10,000 configurations plus glass flat roof windows under the iWindow super-insulating and Vitria sub-brands) and terrace coverings (aluminum structures including Calista, Climalux, Climacrown, SkyRoll, and Pergolux). Adjacent offerings include renovation frames for demolition-free replacement, screens and sunshades, smoke and heat extraction systems, and plastic sheet accessories.

The company's go-to-market combines a direct-to-consumer e-commerce storefront with a domestic network of sales points, resellers, and professional installers across Belgium, plus a dedicated B2B channel (Pro Center, Architect Studio, and B2B Configurator/CPQ) targeting architects, builders, and specifiers. Tools include an EPB U-value calculator for energy performance compliance and structural calculation software (Climafast/Pergofast) for veranda design. Products are produced and stocked in-house, shipped assembly-ready ('montageklaar') within five working days. Skylux earns revenue primarily through one-time product sales to homeowners and to professional installers/architects; no public pricing or revenue figures are disclosed. The company has no subsidiaries, no external funding, and remains under family control.

Direct peers

• Fakro: Polish manufacturer of roof windows, flat roof skylights, and loft ladders. Directly competes with Skylux in plastic and glass flat roof windows across Europe, with overlapping product positioning in mid-market and premium insulation tiers.
• Keylite Roof Windows: UK/Irish roof window manufacturer offering integrated flashing and insulation solutions. Comparable to Skylux as a regional manufacturer of roof windows with installer-focused product ranges and similar mid-market positioning.
• Roto Frank: German manufacturer of roof windows and hardware systems. Competes with Skylux in the European flat-roof daylight category, particularly in pitched and flat roof window segments aimed at residential renovation.

Broad incumbents

• Reynaers Aluminium: Belgian manufacturer of aluminum building solutions including windows, doors, sliding systems, and veranda profiles. Comparable to Skylux's aluminum veranda and terrace covering business (Calista, Climalux, Climacrown) at the systems level.
• VELUX: Danish-founded global leader in roof windows and skylights. Operates broadly in the same daylight category as Skylux, including flat roof solutions, smart-home integration (VELUX ACTIVE), and a much wider international distribution footprint.
• Renson: Belgian family-owned group specializing in ventilation, sun protection, and outdoor living (terrace coverings, verandas, screens). Operates in Belgium alongside Skylux with overlapping outdoor-living product categories but a much broader portfolio and international footprint.

Regional players

• Gibus: Italian manufacturer of terrace coverings, verandas, and bioclimate pergolas. Directly comparable to Skylux's Calista, SkyRoll, and Climacrown lines, but serving primarily the Italian and southern European market rather than Belgium.
• Atlas Roof Solutions: UK roof window and flat roof light manufacturer. Comparable mid-sized regional peer to Skylux in the daylight category, with similar installer-led distribution and a renovation/upgrade focus, though focused on UK rather than Belgian market.
• Weinor: German manufacturer of awnings, terrace roofs, and glass rooms. Comparable to Skylux's outdoor living products (SkyRoll retractable screen, Calista terrace covering) but with primary geographic focus on Germany and central Europe.

Emerging players

• Solatube International: US-headquartered manufacturer of tubular daylighting devices (TDDs). Adjacent to Skylux in providing flat-roof daylight solutions but with a different delivery technology (tubular vs. dome/flat roof window) — a complementary rather than direct competitive threat.
