An Insulation Subcontractor for Airdrie Builders, Basement Developers & Renovators

On a build or a basement development, insulation is the trade that sits between rough-in and drywall, and it is the one an inspector looks at closely. A missed poly hat, an unsealed lap at the top plate or a batt stuffed around a wire is cheap to fix before board goes up and expensive after.

We work as the insulation subcontractor for home builders, basement developers and renovation contractors around Airdrie, Rocky View County and north Calgary. The job is simple to describe: show up when the schedule says, install what the drawings call for, and leave the walls, ceilings and rim joists ready for inspection.

Inspection-ready vapour barrier

Six-mil poly lapped over framing and sealed with acoustical sealant, sealed at top and bottom plates, poly hats or airtight boxes at every electrical box, and continuity carried through at rim joists and headers. These are the details that fail inspections, so they are where we spend the time.

Batts cut to the cavity

Fibreglass or ROCKWOOL Comfortbatt friction-fit to the stud size, split around wiring instead of compressed behind it, and cut tight around boxes and plumbing. The printed R-value only means something when the cavity is actually full.

Closed-cell foam where batts struggle

Rim joists and header areas, cantilevers, bonus room floors over garages and awkward framing are where batt-and-poly details most often go wrong. Closed-cell foam air-seals and insulates those spots in one step, with the thermal barrier the foam requires planned into the drywall scope.

Suite separations as drawn

For secondary suites we install the acoustic insulation and the sealing details the permit drawings name. The sound result depends on the whole assembly, including the resilient channel or clips and the drywall, so we coordinate with whoever is boarding rather than treating the batts as the whole answer.

Attic air sealing before the blow

On renovations and additions we seal top plates, stacks, wiring and fixture penetrations before blowing the attic, install baffles to keep soffit vents clear, and mark depth so the finished level can be read from the hatch.

Paperwork a GC can file

WCB coverage and liability insurance certificates on request, product data sheets for what was installed, and for spray foam the site records the installation standard asks the installer to keep.

How we fit into your schedule

  • Send the drawings or a walkthrough and we price from the actual assemblies, not a rough square footage
  • Book us after framing, electrical, plumbing and HVAC rough-ins are done, so nothing gets cut through our work
  • Tell us the inspection date; the insulation and vapour barrier are finished before it
  • If something on site does not match the drawings, such as a missing fire block or an unvented bath fan, we flag it before covering it
  • We clean up our offcuts and leave the space ready for drywall

Builders & Renovators: Questions

Can you work from the permit drawings for a basement development?
Yes. The drawings tell us the wall and ceiling assemblies, the insulation values, and any sound or fire separation for a suite. We price and install to those, and point out on site anything that does not match what was drawn, before it gets covered. If there are no drawings yet, the designer or the permit office is the first stop, not us.
Do you install the thermal barrier over spray foam?
Drywall over foam is normally the drywaller’s scope. Where drywall is not practical, such as in some garages, crawl spaces and mechanical rooms, an intumescent coating that has been tested and accepted with that foam may be an option, and we can apply it. Which is needed, and whether it is needed at all, is settled with the drawings and the inspector.
How much notice do you need before a job?
It depends on the season and the size of the job, so the honest answer is to call as soon as framing is booked and give us the rough-in and inspection dates. We will tell you straight away whether we can make them rather than agreeing to a date and hoping.
