Frequently Asked Questions (FAQs)
What R‑value do I need for basement walls in Ottawa?
Ontario Building Code calls for R‑17 (RSi 3.0) minimum; we target R‑24 with 2″ closed‑cell foam plus batt Ontario.Will spray‑foam trap moisture?
No—closed‑cell foam is <1 perm; when installed against concrete it blocks water vapour but still allows interior drying through controlled ventilation Natural Resources Canada.How long does the install take?
Typical 1 000 ft² basement = one day for spraying, one day for trimming & fire‑cover.Can I DIY batt insulation instead?
Batt alone often leaves gaps at rim‑joists and penetrations; our hybrid system air‑seals first, then fills cavities Natural Resources Canada.
