Passive House Doors

Thermally broken doors built for low-energy homes.

What Makes a Passive House Door

A passive house door limits heat loss through the frame, glass, and seals. WANJIA Hiseng builds these doors with thermal break profiles, triple glazing, and multi-point locking that pulls the panels tight against the gaskets. The result is a door that supports the performance targets of low-energy building projects.

We do not assign a passive house label to any product. Instead, we describe the construction and let you evaluate it against your project requirements. The same platform used in our 91 series aluminum tilt and turn windows, with a Uw of 1.4 W/m²K, is available for door configurations.

Every door is made to order. You specify the rough opening, glazing, finish, and hardware. Our team confirms the details and provides a quote within 3 hours on average.

Construction Details That Matter

These are the core elements we use to reduce thermal transfer in passive house door applications.

Thermal break profiles

Aluminum frames with a non-conductive barrier between inner and outer sections reduce heat flow through the frame.

Triple glazing option

Three panes with insulating cavities and Low-E coatings cut heat loss and improve comfort near the door.

Multi-point seals

Compression gaskets around the full perimeter work with the locking system to limit air leakage.

Custom sizing

Doors are built to your rough opening dimensions, not stock sizes, so the frame fits the building envelope.

Choosing the Right Passive House Door

Start with the rough opening. Measure width and height at three points and use the smallest dimension. This ensures the door frame seats properly and the seals compress evenly. For large openings, consider a passive house sliding door or a tilt and slide configuration to manage panel weight and operation.

Think about how the door will be used. A passive house front door sees daily traffic and needs durable hardware. A passive house patio door may prioritize glass area and ease of operation. We can build swing, tilt and turn, or sliding doors with the same thermal break and glazing options.

Questions buyers ask

What is the difference between a passive house door and a standard exterior door?

A passive house door focuses on reducing thermal bridging and air leakage. It uses a thermally broken frame, multiple gaskets, and often triple glazing. Standard exterior doors may have less insulation and simpler seals. We build doors to these higher performance details without claiming any passive house certification.

Can you make passive house sliding doors or patio doors?

Yes. We can configure sliding and patio doors with thermal break profiles, triple glazing, and multi-point seals. The same principles apply: limit heat transfer through the frame and glass, and ensure tight compression when closed. Custom sizes are available.

Do you offer passive house entry doors with sidelights?

We can build entry doors with fixed sidelights or transoms. The entire assembly uses the same thermal break and glazing options. You provide the rough opening dimensions, and we design the door and sidelight combination to fit.

Are these doors tested for passive house standards?

We do not claim passive house certification for our doors. Our products are built with thermal break and triple glazing details that support low-energy building goals. You can request specific performance data for the glazing and frame materials.
