West Harbor House is a reference site focused on energy-efficient window systems for cold-climate construction and renovation in Canada. The material covers double and triple glazing configurations, frame materials, and installation standards, with attention to the conditions specific to Canadian climate zones.
Scope
The site addresses the technical side of window selection and installation for residential and light commercial projects in cold climates. The content draws on publicly available technical standards, building code documents, and manufacturer technical literature. It does not represent any manufacturer, supplier, or trade association.
Topics covered include:
- Insulated glass unit configurations — double and triple-pane units, gas fills, low-E coatings
- U-value and thermal performance comparisons for Canadian climate zones
- Frame materials — wood, PVC, fiberglass, and aluminum-clad options
- Installation requirements under the National Building Code of Canada
- Air sealing, flashing, and moisture management in cold-climate assemblies
Content Policy
Articles on this site aim to be factually accurate and based on verifiable sources. Statistics and performance values are drawn from manufacturer documentation, national standards, or publicly available research where noted. Where exact figures are unavailable or context-dependent, the text uses qualified language rather than presenting uncertain numbers as definitive.
The site does not publish sponsored content. Where external links are included, they point to government sources, standards bodies, or established technical organizations relevant to the topic.
Limitations
Building science is not static, and standards documents are revised on a regular cycle. Readers applying information from this site to a specific project should verify current code requirements with the local authority having jurisdiction and consult qualified professionals for project-specific advice. This site does not provide engineering advice or project specifications.
