Spray Foam Insulation in Beaumont, AB.

80.1% of dwellings are single-detached — a high share — and the 2020 median household income here, $130,000, is the highest of the 27 communities compared in this ledger.

New, detached and well-resourced changes what the work is. With only 827 pre-1980 dwellings in the whole city, retrofit-for-comfort is a small market and finishing-and-extending is the large one: heated garages and workshops, bonus rooms over unheated garage ceilings, basement development below a floor that was never detailed as a conditioned boundary, and cantilevered rooms over outside air. These are all cases of an envelope being moved outward rather than repaired, and in a house built to modern code the new boundary has to be made continuous with the old one or the assembly simply relocates the cold spot.

Beaumont has no climate station. The ledger assigns EDMONTON INT'L A (climate ID 3012205), about 10 km southwest — 5,697 heating degree days at an 18 °C base, an average January daily minimum of -18.1 °C, and -44.4 °C at the recorded extreme. Leduc and Nisku are assigned the same station, so all three carry identical winter figures for that reason alone.

Beaumont's industrial context is adjacent rather than internal: the Nisku Industrial Park is roughly 4 km west, and Edmonton International Airport about 8 km southwest. Both are large-format industrial and airside building stock, which is a different envelope proposition from the residential city itself.
