HH Windows & Doors

What HH Windows & Doors does

HH Windows & Doors is a privately held custom wood window and door manufacturer founded in 1994 in Seattle, Washington by Hannes Hase. The company adapts European tilt-turn window technology and German engineering principles for American-made production, manufacturing every unit to order in its single Seattle facility equipped with European machinery and staffed by skilled craftsmen. Its product portfolio centers on wood tilt-turn windows achieving Passive House-level U-values as low as 0.16, complemented by aluminum tilt-turn windows, bifold windows and doors (up to 24 feet wide), lift-slide doors (up to 60 feet wide), pivot windows, and custom European-style entry doors with triple-overlay construction and multi-point locking. The company also distributes third-party product lines from Reynaers Aluminium (Belgium) and REHAU (Germany), giving it access to slim-profile aluminum and fiber-composite uPVC Passive House-certified systems without internal R&D burden.

The business operates a consultation-led, quote-based sales model targeting luxury home builders, architects, and Passive House builders across the Pacific Northwest, West Coast, Mountain West, Northeast US, and Canada. Marketing is primarily content- and referral-driven through the company website, educational blog, social channels (Facebook, Instagram, LinkedIn, Houzz), and free project consultations, supported by a recommended installer network. Revenue is generated through one-time purchase transactions for custom-manufactured units, supplemented by third-party product resales and pre/post-sale engineering and consultation services. Pricing is not publicly disclosed but is positioned at the premium end of the market, justified by European craftsmanship, Passive House-grade performance (U-values down to 0.13–0.16, up to 47 dB acoustic rating, up to 90% reduction in heating demand), and custom configuration. The company is self-funded with no disclosed external investors, holds no patents in the data set, and operates with a small named team of five covering production, finishing, and project sales.
