CALGARY ATTIC INSULATION

Attic insulation in Calgary is typically blown-in fiberglass installed to about R-60 over a vapour sealed, properly ventilated attic. A standard attic takes 3–4 hours. Sorell Insulation seals vapour and air leaks first, protects soffit airflow with soffit baffles, installs Johns Manville Climate Pro, and documents the finished depth with markers and photos

Why it matters in Calgary:

Calgary winters push heat out through the attic. Warm, moist air escaping into a cold attic is also what causes frost, damp insulation and ceiling stains. Adding insulation helps, but sealing the air leaks and ventilating the attic correctly is what makes it last.

Signs your attic needs attention:

cold rooms upstairs, ceiling water stains, frost on the underside of the roof deck in winter, ice dams or uneven frost and snowmelt on the roof, high heating bills, insulation that looks thin, compressed or contaminated, or a home inspector’s note.

 How we do it

1. • Inspect: we check insulation depth, ventilation, bathroom fan ducting and signs of moisture.
   • Prepare: we seal air leaks, repair the vapour barrier where needed, and install baffles at the soffits.
   • Insulate: we blow in Johns Manville Climate Pro to the target depth.
   • Verify: depth markers are installed and we send you photos of the finished work.

Attic Insulation Inspection and Installation Guide

Attic Insulation Inspection

1. Identify Issues: Advise our inspector on any problems related to your insulation and ventiation. This includes water stains on drywall (ceiling or wall), temperature issues in specific areas of the house, or comments made by home inspectors.
2. Access Attic Hatches: Locate and provide access to all attic hatches. If an attic hatch is in a closet, remove personal items to allow our inspector easy access. 

Attic Insulation Installation Preparation

1. Time Estimate: Budget 3 – 4 hours for a standard attic insulation installation. Jobs involving insulation removal or extensive vapor barrier repair may take longer.
2. Minimal Disruption: Don’t worry about clean-up. Our crews are experienced in upgrading lived-in residences daily. We lay down drop sheets and install poly sheeting from within to the attic hatch and clean up thoroughly upon completion, ensuring minimal disruption to your household.
3. Separate Roofing Work: Any roofing work quoted may be executed by a different crew. While all work is part of the Sorell Insulation family; roof vents, goosenecks, or soffit venting may be installed by our roofing department during a separate site visit. You will not be invoiced until all work is completed to your satisfaction.
