Western Insulation is a certified ProPink installer — using Owens Corning's GREENGUARD Gold certified blown-in fibreglass for every Langley BC attic upgrade. ProPink is non-combustible, moisture-resistant, and backed by a lifetime limited warranty when installed by a certified contractor. At R-2.5 per inch, reaching R-60 in a Langley attic requires approximately 24 inches of blown-in — a depth our team achieves in a single day without disrupting finished ceilings below.
