What EnerLux Windows & Doors does
EnerLux Windows & Doors is a family-owned custom manufacturer of fiberglass windows and doors, founded in 2008 and headquartered at 1530 Pine Avenue, Crete, Nebraska. The company designs, engineers, and fabricates pultruded fiberglass window and door products for residential new-construction and replacement projects, with a secondary commercial and light-commercial offering up to CW-PG80 performance ratings. Its core technology centers on a proprietary Super Strength Corner (S2C) System that uses a two-component adhesive chemically fused at window corners, combined with thick-walled pultruded fiberglass frames, CNC-mitered corners, and EPS-foam-filled frames, achieving air infiltration as low as 0.02 cfm and enabling windows built up to 30% larger than competing material windows. The product line spans casement, awning, picture, custom-shape, and sliding patio doors, with glass supplied exclusively through a partnership with Cardinal Glass and hardware sourced via Roto.
Revenue is generated through one-time product sales to homeowners and builders via direct sales, dealer networks, and builder partnerships, with pricing conducted on a quote basis and not publicly disclosed. The go-to-market is sales-led: customers reach the company by phone, email, or a request-a-quote form on the website, and the company maintains an inside sales team supporting builders across the Midwest. Marketing includes an organic-social presence on Facebook and YouTube, a Blog, a Yelp listing, an earned-media feature on The Build Show, and a 2026 downloadable brochure. Only two named customers are visible in the data set — Tevelde And Co. (SMB window installation contractor in Omaha, Nebraska) and Colorado Lifestyles (custom home builder in Colorado) — consistent with a small, regionally distributed specialty manufacturer.
