Passive House Window & Door Installation
Expert installation for Passive House and Net-Zero Energy Buildings
At Fentec, we don’t just install windows and doors — we integrate them into the most demanding building envelopes in the world. Specializing in Passive House (Maison Passive) and net-zero-ready construction, our team brings unmatched precision and technical knowledge to every project. We align with the Passive House Institute (PHI) standards, ensuring every installation contributes to the airtightness, thermal integrity, and energy performance of the structure.
Why Passive House Installation Is Different
Passive House buildings, as defined by the Passive House Institute, require:
- Airtightness ≤ 0.6 ACH@50Pa.
- High R-value walls and glazing assemblies.
- Thermal bridge–free design.
- Controlled ventilation with heat recovery.
- Accurate solar orientation and shading strategies.
Windows and doors are often the weakest link in an otherwise airtight envelope. Poor installation can lead to air leakage, thermal bridging, and condensation risk — all of which threaten the building’s performance certification.
That’s where we come in.
Our Installation Protocol: Engineered for Performance
- Passive-Certified Components, Installed with Precision
We work with PHI-certified components wherever possible, including triple-glazed windows with insulated frames, warm-edge spacers, and high-performance door assemblies.
- Advanced Sealing Systems
We implement airtight detailing using vapor-variable membranes, resilient sealing tapes, and expanding foam or backer rod systems — all compatible with PHI-recommended air barrier strategies.
- Continuous Insulation & Thermal Breaks
Our team installs thermal breaks and exterior insulation around all openings, ensuring continuity of the building envelope. No fastener or shim is left unconsidered in our detailing.
- Integration with Design & Energy Modeling
We collaborate closely with architects, passive house designers, and energy consultants to ensure all fenestration installs align with the energy model and solar gain strategy. Window placement, orientation, and depth are executed exactly as designed.
- CSA-A440 & Passive House Alignment
Every installation meets or exceeds CSA-A440 performance standards and is informed by best practices outlined by the Passive House Institute (PHI) and PHIUS methodologies.
Always Learning. Always Improving.
Fentec’s commitment to Passive House construction is not a marketing trend — it’s a professional standard. Our team stays actively informed on:
- New materials and thermal insulation technologies.
- Updated PHI and PHIUS protocols.
- Advanced airtightness detailing techniques.
- Changes in local building codes affecting high-performance construction.
- Accurate solar orientation and shading strategies.
We invest in training, technical documentation, and real-world testing to continually improve our craft — because the performance of your Passive House depends on more than just great products. It depends on flawless installation.
