If your Langley attic was insulated before 2000, there is a very good chance it is sitting at R-20 or R-30 — well below the current BC Building Code minimum of R-40 to R-50 and the R-60 that Western Insulation recommends for real-world comfort in the Fraser Valley. That gap translates directly into heat escaping through your roof every winter, your furnace working harder than it should, and energy bills that are higher than they need to be. Blown-in fibreglass is the most effective way to bring an existing Langley attic up to R-50 or R-60 quickly and without disruption.
