Langley homes built before 1977 were frequently constructed with 2x4 framing and either no wall insulation at all or minimal fibreglass batts providing around R-8 to R-11. Homes from 1977 to 1995 typically have R-12 batts — still well below current BC code requirements of effective R-22 to R-24. If your Langley home falls into either category, upgrading your wall insulation with dense-pack blown-in insulation is one of the highest-impact energy efficiency improvements available to you. Western Insulation inspects every home before recommending a solution, so you know exactly what your walls contain and what the upgrade will deliver. We also check eligibility for BC Hydro and FortisBC rebates of up to $5,500 on qualifying projects.
