About This Site
An informational reference on residential insulation and thermal envelope performance in Canada.
What this site covers
GoldenWindowCo.org publishes reference material on residential building insulation, air sealing, and draft prevention, with a focus on the practical conditions that apply to homes in Canada. The content is written for homeowners, building science students, and tradespeople who want factual, unbiased descriptions of how insulation systems work.
The site does not sell products, recommend contractors, or promote any commercial service. All information is based on publicly available technical sources, including the National Building Code of Canada, Natural Resources Canada publications, and peer-reviewed building science literature.
Editorial approach
Articles are written in a descriptive, informational style. Figures cited on this site are drawn from official sources. Where precise data is not available from a verifiable source, the text uses neutral language rather than invented statistics.
Content is updated periodically as building code requirements change or new research becomes available. Each article includes a last-updated date.
Topics covered
- Types of residential insulation materials (fiberglass, mineral wool, cellulose, spray foam, rigid foam)
- R-value and effective thermal resistance explained
- Air leakage: detection methods and sealing approaches
- Moisture management in insulated assemblies
- Climate zone requirements under the National Building Code of Canada
