Linel

What Linel does

Linel, founded in 1978 and headquartered in Mooresville, Indiana, is a custom engineered architectural skylight manufacturer serving major architects, cultural institutions, and large commercial and infrastructure projects across the United States. The company operates as a subsidiary of Mestek, Inc., a diversified industrial conglomerate. Linel's core capability is the design, engineering, fabrication, and installation of complex, highly customized skylight systems — including the SG1000 glass skylight system, the pressure-equalized SG2000 system, the segmented curved SG3000 system, the hurricane-rated HR2000 system (Miami-Dade approved to +/-120 psf), and the Pyra-Dome framing system — alongside a four-system rainscreen panel family, glass and metal canopies, architectural panels, brake metal, and a vertically integrated in-house Kynar 500 paint line capable of finishing parts up to 30 feet in length.

Linel's business model is project-based and quote-driven, with all projects custom engineered and priced per scope; the company describes engagements ranging from $100K to multi-million dollar, multi-year buildouts. Revenue is generated through one-time custom manufacturing and installation contracts, design assist professional services, and architectural painting services. Go-to-market is enterprise field sales targeting "major renowned and progressive architects" (Renzo Piano, Gehry Partners, Thomas Phifer, Selldorf, Beyer Blinder Belle, Perkins+Will, HOK, SOM) supported by a nationwide sales representative network accessed via a zip-code Sales Locator tool. Customer segments are organized vertically — museums and cultural institutions, universities, healthcare facilities, commercial real estate, and transportation infrastructure — and landmark projects include the Metropolitan Museum of Art (27 skylights, 30,000 sqft, 3 years), the Guggenheim restoration, the High Museum of Art expansion (1,000 skylights), the Corning Museum of Glass (25,000 sqft), and the Orlando International Airport landside terminal (1.4 acres). The company holds multiple industry awards including Harleston Parker (2019), IDEAS (2019), ENR Merit (2018), and North American Copper in Architecture (2010).

Broad incumbents

• Kingspan Light + Air: Kingspan Light + Air is a large established manufacturer offering skylights, smoke vents, and daylighting solutions as part of a broader building envelope portfolio. It competes with Linel across commercial skylight scopes but as part of a much wider product range and global footprint.
• Oldcastle BuildingEnvelope: Oldcastle BuildingEnvelope is a leading US manufacturer and supplier of architectural glazing systems including curtain walls, storefronts, and skylights. It competes with Linel on engineered metal and glass envelope work but with broader, more standardized product lines.
