Passive House windows are the foundation of energy-efficient builds. HH Windows & Doors designs and manufactures Passive House windows and doors that meet the highest standards for airtightness, insulation and comfort. We offer a wide selection of additional materials and systems—including uPVC, fiberglass and aluminum tilt and turn doors to meet your individual style preferences, performance goals and budget requirements. Serving clients from Seattle to San Francisco to Los Angeles, and as far east as New York, our products support builders, architects and homeowners where performance and design go hand in hand.
Passive House is the world’s leading energy-efficiency standard. These buildings are super-insulated, virtually airtight, and rely on passive solar gain and internal heat sources to maintain comfort. With triple-glazed windows, advanced insulation, airtight shells, and energy recovery ventilation, Passive House design can cut heating demand by up to 90% while providing outstanding indoor air quality.
HH Windows & Doors is one of the few North American manufacturers producing Passive House–grade windows and doors. Unlike bulky European imports, our designs feature slimmer profiles and cleaner glass lines, better suited to American architecture—without sacrificing performance.
Our products achieve exceptional thermal efficiency through advanced engineering and premium materials.
Result: U-values as low as .16 for industry-leading performance.
Along with our own manufacturing, we proudly supply premium products from Cascadia Window & Door and Prime Window Systems, ensuring you have access to the right solution for any build.
Even if you don’t require Passive House certification, our standard windows and doors outperform most conventional American products. We can customize to virtually any U-value to meet your project’s needs.
