Not all walls in your Langley home lose the same amount of heat — and knowing where to start means you get the most impact for your investment. North-facing exterior walls lose the most heat through BC winters and are the most susceptible to condensation forming on the interior wall surface. Walls adjacent to unheated garages are often completely uninsulated in older Langley homes despite being in direct contact with living spaces. Walls surrounding basement suites and secondary suites are a priority for both thermal performance and the soundproofing benefits that dense-pack insulation delivers. Gable end walls in attic spaces are frequently overlooked but fully exposed to the outdoors. Western Insulation identifies your priority walls first, then works through the rest systematically.
