Verified performance
PHI-certified and modelled configurations provide the frame, glass, spacer and whole-window information needed for Passive House, net-zero and Step Code 5 work.
Certified Passive House systems
Five PHI-certified window and door systems. Made in Canada.
Fenstür manufactures two PHI-certified window systems and three PHI-certified entry-door systems in Duncan, British Columbia. Listed under Wescon Cedar Products Ltd., they bring all-wood and wood-aluminum design options to Passive House projects across Canada and the United States.

The distinction matters
Certified systems. Freedom to design.
Two window systems. Three entry-door systems. Each PHI certificate documents a construction system, including its profiles, junctions and installation details.
Custom sizes, flexible opening arrangements and coordinated window-and-door designs bring the system to your project.

02
Design flexibility
Choose from certified all-wood and wood-aluminum window and entry-door systems.
03
Early collaboration
Sizing, glass, solar gain, operability and installation details are reviewed while they can still improve the building model.
04
North American delivery
Canadian manufacturing, NAFS and NFRC documentation, direct service and Fenstür-coordinated delivery reduce the uncertainty of importing a distant European package.
05
Material-conscious construction
Documented wood-system options can support Living Building Challenge material goals while preserving the performance, durability and natural interior character of a substantial timber frame.

Two exterior expressions
Every product. All wood or wood-aluminum clad.
Both begin with the same engineered timber structure and the same warm, genuine-wood interior. The choice is about exterior expression, exposure, maintenance and budget.
Compare materials + finishes
All wood
Real wood is visible inside and outside. It offers the fullest natural-material expression and typically the lower initial cost.
- Best for protected or thoughtfully detailed elevations
- Maximum species, stain and paint flexibility
- Exterior finish needs periodic inspection and care
Wood-aluminum clad
A ventilated, powder-coated aluminum skin protects the exterior while the full warmth of timber remains visible inside.
- Ideal for high exposure and lower-maintenance goals
- Broad exterior colour selection
- Higher initial investment for added weather protection

Simple technical overview
106 mm timber. Triple pane performance.
Normally paired with high-performance triple pane low-e glazing.
Coatings and solar heat gain are selected for the building model and orientation.
Fenstür holds documented all-wood and wood-aluminum-clad certified window configurations.
PHI certificates and technical documentation support your energy model.

Case study · The Green Point Project
One high-performance home, several coordinated opening types.
The Green Point Project brings together aluminum-clad tilt-and-turn windows, a custom red front entry door, picture windows and a lift-and-slide opening. The result shows how high-performance detailing can support natural timber interiors, broad views and a strong architectural identity.
02
Certified scope
Five certified systems, with documented design flexibility.
Fenstür offers two certified window systems and three certified entry-door systems: solid wood, glazed wood and glazed wood-aluminum.
- Listed window-system configurations for project review
- Certified fixed picture-window configurations
- Three certified entry-door systems in the PHI database
- Wood and wood-aluminum-clad certified options
03
106 mm system
Cork insulation inside a substantial timber frame.
The 106 mm series uses over 4⅛ inches of engineered timber and is normally paired with thick triple pane low-e glass. In documented Passive House configurations, cork insulation is incorporated in the solid wood frame to improve thermal performance while maintaining slim sightlines and real-wood interiors.
- Two continuous gaskets support air- and water-tightness
- Multipoint locking controlled by one handle
- Anti-sag support for large or heavy sashes
- Profile-changing technology increases glass area and strength
- Cork-insulated window and door options
04
Why wood
The logical material for responsible high-performance building.
Passive House should be about responsible building—not only low heating demand. Responsibly sourced wood is local, renewable, recyclable, repairable and supported by an ethical, transparent supply chain. It stores carbon, can be maintained rather than discarded and connects long-term performance with natural-material stewardship. Other frame materials may meet an energy target, but when they are energy-intensive, disposable or difficult to repair, they conflict with the broader philosophy Passive House is meant to advance.
05
Why Fenstür
Performance is a project conversation—not a glass upgrade.
Passive House design depends on the complete opening: frame, sash, glass, spacer, installation position, air-barrier continuity, shading and orientation. Fenstür helps the project team coordinate those decisions rather than treating the window schedule in isolation.
06
A trusted local partner
European-inspired performance without an overseas handoff.
Fenstür combines advanced European window technology with Canadian manufacturing, North American testing and direct support from the people building the product. That means clearer communication, practical shipping and easier follow-through when a project detail changes.
- Project-specific glass and solar-gain review
- Support for architects, builders and energy advisors
- Custom sizing without standard-size surcharges
- Locally and domestically sourced wood species
- Solid laminated timber with no exposed finger joints
- Living Building Challenge-compliant product options
- Fenstür-truck delivery for suitable regional projects
- Delivery throughout Canada and the United States
