Do you know what R-value your Langley home actually needs — or are you just hoping the contractor got it right? Most homeowners in the Fraser Valley have never had their insulation checked against current BC Building Code requirements, and the gap between what they have and what they need is costing them money every single month. Langley falls within BC Climate Zone 4, which requires R-50 or higher in the attic, R-22 to R-24 in exterior walls, and R-20 in basement and crawlspace walls. Western Insulation breaks down every zone of your home in plain, honest language so you can make informed decisions before you spend a dollar.
