Insulation for New Builds in Calgary and Edmonton
New construction insulation is a significant part of what we do. Through an established network of drywall contractors, our crews work on residential and multi-family projects across Calgary and Edmonton on a daily basis. That volume gives us a realistic understanding of construction schedules, trade sequencing, and what builders actually need from an insulation contractor.
We install fiberglass batt and poly for exterior walls and interior partitions, Roxul (Rockwool) mineral fibre batt for party walls and assemblies with fire or acoustic requirements, blown-in fiberglass for attic floors, and spray foam for rim joists, frost walls, and other areas where the geometry or performance requirements make batt insulation the wrong choice. Each zone of a build gets the product that’s appropriate for it.
We can price your project from architectural plans at any stage of the development cycle, or complete a site measure once framing is done, whichever is more useful for your timeline.

What Builders and Developers Get from IDEAL
Working with the same insulation contractor across multiple projects gives builders a reliable baseline. You know how they quote, how they communicate, and whether their work consistently passes inspection. These are the things that matter most to builders choosing an insulation contractor, and they’re the things we’ve built our reputation on over 45 years of new construction work in this market.
What Goes Where: A Typical New Construction Scope
Every new construction project is different, but the product decisions across the main building zones follow a consistent logic driven by code requirements and the physical demands of each assembly.
A note on party walls
This is the area where specification errors are most common and most consequential. Fire separation between dwelling units is a National Building Code requirement. Roxul mineral fibre batt is the correct product for demising and party walls because it’s non-combustible. It won’t melt or drip in a fire. Fiberglass batt does not meet this requirement in the same way. If you’re managing a multi-family project and a contractor is quoting fiberglass on party walls without explaining how they’re addressing the fire separation requirement, that’s a conversation worth having before construction starts.
A note on vapour barriers
The vapour barrier installation is the step that most commonly creates inspection delays in new residential construction. Every electrical box, plumbing penetration, recessed light, and wall plate needs to be properly sealed. The difference between a vapour barrier that passes inspection and one that doesn’t usually comes down to how carefully this work was done, not which poly product was used. Our crews treat it accordingly.

“We’ve used IDEAL across three production developments over the past several years. Their quotes are accurate, their crews show up when the framers are done, and I’ve never had to chase them on a deficiency. That consistency is what keeps them on our approved list.”

Google Review — New Construction Insulation, Calgary
“IDEAL handled insulation across two buildings in a 96-unit development, phased over eight months. The party walls were specced correctly with Roxul from the start, everything passed inspection on the first visit, and the drywall trade had no complaints going in. The coordination between their project contact and our site super was smooth throughout.”

“As an owner-builder on a custom acreage project, I wasn’t sure how IDEAL would approach something my size. They treated it with the same care as any other project. The estimator explained every decision, the crew left the site clean, and the inspection came back with no deficiencies.”

Common Questions from Builders
Yes. We can produce a detailed takeoff from architectural drawings at any stage, which is useful for early-stage project budgeting. We follow up with a site measure for final pricing once framing is done.
Current Alberta Building Code requires a minimum of R-20 for exterior walls, which calls for 2×6 framing with fiberglass batt. Attic floors are typically insulated to R-50 or R-60. Requirements vary by assembly type and building classification. If your architect or energy consultant has specified values above code minimums, we quote to those specifications.
The National Building Code requires fire separation between dwelling units in multi-family buildings. Roxul mineral fibre batt is non-combustible. It won’t melt or drip in a fire, which fiberglass batt will. For demising walls and party walls, the two products are not interchangeable from a fire separation standpoint. We specify Roxul for these assemblies as a matter of course.
Yes. Production builds, custom homes, low-rise and mid-rise multi-family, and mixed-use residential. The same product range and installation standards apply regardless of project size.
We assign one project coordinator who manages scheduling and sequencing across all phases for the duration of the project. That person is your contact for scheduling updates, scope questions, and anything else that comes up. You’re not relaying information through a general line.
Yes. We have crews operating in both cities and have worked across both markets since 1979. For developments that span both cities or surrounding communities, we handle the full scope without requiring separate contractors.
If a deficiency in our work causes a failed inspection, we return and correct it at no additional cost. This is covered under our 10-year workmanship guarantee.
