Quality is the Difference
Grade A Is Quality
Simply passing an insulation inspection does not mean it is a job well done. Grade A has set numerous standards for our installers that most competitors cannot rightfully claim. You should find each of the following qualities on every job we do:
No Batt Compression
Every batt installed at full thickness to deliver the rated R-value — never compressed.
Attic Rulers Installed
Rulers confirm accuracy of attic insulation depth on every job.
Poly Taut with Joints Overlapped
Vapour barriers installed taut with overlapping joints for a complete seal.
R-Value Visible
Insulation R-value clearly visible for inspection on every install.
Signed Attic Cards
Attic cards left, signed and dated by the installer on every project.
Split Insulation Around Wiring
All electrical wires properly split and wrapped for safety and coverage.
Caulk All Outside Corners
All exterior corners caulked to eliminate air infiltration.
Dam and Strap Knee Walls
All knee walls properly dammed and strapped per code.
Porch Area Blocking
Areas above porches blocked with batts or poly to protect blown-in insulation.
Clean Job Site
All scrap and garbage removed from the job site before we leave.
