Unilite

What Unilite does

Unilite A/S is a Danish manufacturer founded in 1988 that designs, produces, and services skylights, automatic fire ventilation (ABV) systems, and comfort ventilation units for the Scandinavian market. Operating from its own factory in Hobro, Denmark, with a wholly-owned Norwegian subsidiary (Unilite Norge AS), the company serves approximately 85 employees organized across skylight, fire ventilation, ventilation, production, and project sales functions. Its core technology spans acrylic, polycarbonate, glass, and EI60 fire-rated skylights; thermal and mechanical ABV systems including the proprietary UniBlaster and WallBlaster units; elevator smoke control systems; and ventilation units supplied under partnership with Lithuanian manufacturer Salda.

The business operates a project-based B2B model targeting architects, contractors, building firms, and project managers through direct consultative selling and a nationwide Danish service technician network. Revenue is generated primarily through one-time hardware sales of custom-manufactured skylights and ABV systems, supplemented by recurring annual service agreements covering inspection, maintenance, and regulatory compliance for installed fire safety installations, plus project consulting and CE marking/certification work. Unilite holds the distinction of being the first Danish company to obtain DBI certification for both thermal and mechanical fire ventilation design, installation, and service, and has maintained ISO 9001 certification since March 2017, with ISO 14001 in progress.

Unilite is a subsidiary of Swedish technology conglomerate Addtech AB, providing group-level capital and corporate governance (including shared whistleblower and code-of-conduct infrastructure). The customer base spans production and manufacturing facilities (primary), logistics and warehousing, commercial buildings and offices, municipal and government projects, food and agriculture sites requiring hygienic skylights, and residential applications. Geographic coverage is Denmark-direct and Norway through the subsidiary; no broader international footprint was disclosed. The company is privately held and does not publish revenue figures.
