Integral Construction
We don't just build. We protect!
At Integral Construction, we look at your home as a complete thermal system. While attic insulation is our most frequent inquiry, true home comfort and energy savings require a comprehensive approach. We provide high-performance blown-in insulation services using premium cellulose and fiberglass to treat your entire building envelope.
From topping up attics to dense-packing exterior walls and insulating basement assemblies, our team ensures your home meets or exceeds modern Alberta Building Code standards, eliminating drafts and lowering your utility bills year-round.
Modern R-Value Standards for Alberta’s Climate
An R-value measures a material's thermal resistance. The higher the R-value, the greater the insulating power. Because Calgary sits in Climate Zone 7, modern building science and energy codes mandate much higher levels of protection than what was required when most local homes were built.
Different areas of your Calgary home require specialized installation methods to stop heat transfer. Our certified crew is equipped to insulate every critical zone:
-
Attic Loose-Fill Blow-In: We restore or upgrade failing attic insulation to modern building standards, creating an unbroken barrier against heat loss.
-
Exterior Wall Retrofits ("Drill-and-Fill"): For older homes in Calgary with drafty or uninsulated walls, we drill small, precise access holes from the exterior or interior to dense-pack loose-fill insulation into empty wall cavities.
-
Basement & Crawl Space Walls: We eliminate the cold concrete "heat sink" effect by treating basement wall assemblies and rim joists to stabilize lower-level temperatures.
-
Garage & Bonus Room Floors: Prevent frozen pipes and cold floors by injecting dense, high-density insulation beneath bonus rooms and inside attached garage walls.
Comprehensive Blown-In Insulation Applications
Recommended R-Values for Southern Alberta
Upgrading your home to these targets can reduce your annual heating and cooling load by up to 30%, quickly offsetting your initial investment.
-
Attic Ceilings: A minimum target of R-50 to R-60 (approximately 16 to 20 inches of settled material). Most older Calgary homes only have R-12 to R-20.
-
Exterior Walls: A target of R-20 to R-24 in wood-framed cavities, which we achieve using advanced dense-pack techniques.
-
Basement Foundations: A minimum target of R-20 to control thermal bridging through concrete surfaces.
