What Greenec OÜ does

Greenec OÜ is an Estonian insulation installation contractor founded in 2021 and headquartered in Nõo, Tartu County. The company specializes in two thermal insulation technologies: blown-in loose-fill insulation (puistevilla) using stone wool, cellulose, or glass wool materials; and spray-applied polyurethane (PUR) foam that expands to form a monolithic, airtight layer. Greenec works with certified materials from established manufacturers including Paroc, Ekowool, Werrowool, Supafil, Isover, Ekovilla, Ekoprodur, and TERA-PUR. Installation services cover foundations, plinths, floors, walls, ceilings, attics, and roofs in both new construction and renovation contexts.

The company's primary customer segment is residential homeowners seeking to reduce heating costs and address thermal bridges, moisture, and mold issues, with secondary reach into apartment buildings and commercial properties. Greenec operates a sales-led, direct-to-customer go-to-market: customers initiate engagement through a website quote request form, phone, or email, and the company delivers a custom quote based on service type, surface area (m²), layer thickness, and address. Pricing is fully quote-based with no public rate card.

Greenec distributes services directly with no resellers, partners, or intermediary channels. Marketing relies on the company website (greenec.ee), search engine optimization, and a Facebook page. The company is privately held, with no disclosed institutional funding, no parent company, no subsidiaries, no patents, no public awards, and no disclosed management team. Operating geography is limited to Estonia.
