Spray Foam Insulation in Rimbey, AB.

68.9% of the stock is single-detached, and the population fell 3.8% between the 2016 and 2021 censuses, so the 527 older houses are not being crowded out by new building.

In older detached stock the heat-loss ranking is usually consistent: the attic plane first, because warm air leaves through the top of the building and takes moisture with it; then the basement perimeter, where a rim joist that is packed batt rather than a sealed assembly loses heat to outside air continuously; then the walls, which are the most expensive to reach and the least likely to pay back on their own. Where budget is finite, that order is the whole plan.

Rimbey has no climate station. The figures quoted for it come from RED DEER REGIONAL A (climate ID 3025480), about 63 km southeast — 5,619 heating degree days at an 18 °C base, an average January daily minimum of -17.6 °C, and -43.8 °C at the extreme. Sixty-odd kilometres is a long borrow; treat the number as regional.

Rimbey's named sites are unusual for their category. Pas-Ka-Poo Park houses the Smithson International Truck Museum, billed as the world's largest collection of International trucks, and Central Alberta Raceways runs a drag strip and a dirt oval track outside town. Museum and motorsport buildings are large-volume, intermittently occupied structures — exactly the case where heating a big shell to a comfortable temperature for part of the year is expensive unless the envelope is continuous.

The town sits adjacent to Gull Lake, the same water body that anchors Bentley's lakeside market on the opposite shore. Lake-adjacent buildings tend to be the ones on intermittent heating schedules, where the priority is a continuous air and vapour seal rather than added depth.
