Rianevex is an independent reading site about the building envelope — the layers of insulation, air control and moisture control that decide how a house holds heat through a Canadian winter. The focus is narrow on purpose: insulation types and R-value, air and vapour barriers, and the detailing of windows and other openings.
What this site is
The entries here summarise published technical guidance in plain language and point back to the original sources so a reader can verify any claim. The recurring references are Natural Resources Canada's Keeping the Heat In series, the National Building Code of Canada as adopted provincially, and provincial publications such as the BC Housing retrofit guides.
What this site is not
It is not a contractor, a supplier, or a government department, and it is not affiliated with any rebate program. It does not sell products or perform home evaluations. Where a topic touches funding or code, the entries describe what the published material says and direct readers to the relevant authority for current, location-specific detail.
How the entries are written
- Each topic states the principle, the practical steps, and the moisture rule that keeps the work durable.
- Figures such as R-values and program amounts are attributed to a named published source.
- Requirements that vary by province or municipality are flagged as such rather than presented as universal.
