Crystal Units

What Crystal Units does

Crystal Units Ltd is a privately held UK-based glass manufacturer founded in 1995, headquartered at 100 W Hendon Broadway, London. The company designs, manufactures, and supplies bespoke glazing solutions for commercial, residential, and heritage construction projects, with a portfolio of more than 20 product categories ranging from standard double-glazed and toughened units to specialist fire-rated, solar-control, structural, and shaped glass. Its commercial differentiators are two proprietary technologies: C.U.in, a triple-glazing system using suspended film technology that achieves U values as low as 0.5W/m²K within standard double-glazed frame depths, and NUCLR, a heated-glazing system using advanced conductive coatings and short wave radio heat for rapid, uniform heating. Additional specialist services include Edge Enamelling (exclusive UK-market finish), Sandblasted Glass (Dow Quality Bond accredited), and Structural Silicone Bonding.

The company's revenue model is project-based and quote-driven, spanning one-off bespoke glazing sales and recurring hardware supply to an approved installer network. Go-to-market is sales-led, with direct enterprise engagement of architects, contractors, and developers for large commercial projects, complemented by a channel model where certified installers purchase C.U.in and NUCLR products for installation in residential and commercial schemes. Customer segments are diversified across Commercial, Residential, Heritage, and an Installer Network; named demand-side customers include Elmsbrook House, QMUL Mathematics Building, The Depot Cinema, The Forge, Windmill Rise, and Watergate. The company holds no parent company, has no disclosed funding rounds, no subsidiaries, and no public listing, indicating it is independently owned and operated with over 30 years of operating history.
