What Zola Windows does

Zola Windows is a US-based manufacturer and direct seller of high-performance, European-engineered windows and doors, founded in 2011 in Steamboat Springs, Colorado and operating as an employee-owned private company. The company serves architects, Passive House consultants, custom and luxury home builders, multi-family developers, and individual homeowners across North America, with physical showrooms in Steamboat Springs CO, Seattle WA, and Park City UT and team coverage spanning three time zones. Customers include named repeat specifiers such as Park City Design + Build, Baxt Ingui Architects, Sorgente Group, Artisans Group, and Indigo Builders, alongside institutional projects such as the University of Northern British Columbia Wood Innovation Research Lab.

The product portfolio spans four frame material lines (Clad Wood, Aluminum, uPVC, and Wood) and multiple sub-brands optimized for distinct performance and aesthetic use cases. Notable proprietary offerings include ZNC (the first window certified by both PHIUS and PHI), American Heritage SDH (approved by Brooklyn and Manhattan historic preservation commissions), Sanctuary Glass (up to 44 STC and 37 OITC acoustic performance), ThermoPlus uPVC (value-tier Passive House, U-value 0.14/hr.sqft), Thermo Alu75 (R-11 standard, R-15 optional), Thermo Wood (R-11 with 18mm spacer), BreezePanel folding walls, LiftSlide and Pocketing LiftSlide doors, Pivot Doors, and Facade Systems. All products are custom-crafted in European factories and shipped directly to US job sites in dedicated containers with lead times of 2-6 weeks. Pricing is quote-based and not publicly disclosed.

Zola's go-to-market is sales-led with event-driven elements: direct sales through showrooms and a website quote-request funnel, paired with architect/builder specification partnerships and sponsorship of Passive House events including Passive House Accelerator (Founding Sponsor) and Passive House Northwest conferences. The company earns revenue primarily through one-time custom window and door sales, supplemented by international shipping services and project consultation support from dedicated project managers and staff architects. The company is privately held and employee-owned with no venture capital funding history, has no public revenue disclosure, and is positioned by third-party sources as the leading luxury/high-performance European window company in the United States and the supplier of more US Passive House projects than any other window manufacturer.
