New Construction Spray Foam Insulation in Mississauga
Insulating a building before the walls close up
New construction is the easiest scenario to insulate well, because crews have full access to open stud bays, roof assemblies, and rim joists before drywall, siding, or roofing cover them up. Foamworks works directly with builders and general contractors to schedule insulation into the framing timeline, typically after rough-in for plumbing, electrical, and mechanical, and before insulation inspection and drywall.

Why timing matters more on new builds than retrofits
On a retrofit, the challenge is access: cutting into finished walls, working around existing wiring, protecting flooring and finishes. On new construction, the challenge is scheduling: spray foam needs specific temperature and humidity conditions to cure properly, and it needs to happen in the window between rough-in and drywall without holding up the rest of the trade schedule. Foamworks coordinates directly with site supervisors and general contractors to fit that window rather than working around it after the fact.
What gets insulated on a typical new build
- Exterior wall assemblies, including rim joists at every floor level
- Roofline or attic assemblies, depending on whether the design uses a vented attic or an unvented “hot roof”
- Foundation walls and slab edges where the design calls for it
- Garages, particularly where they share a wall or ceiling with living space
- Mechanical rooms and any areas with significant duct or pipe penetrations
Working around other trades
Spray foam crews aren’t usually the only trade on site during the rough-in-to-drywall window — electricians, plumbers, and HVAC installers may still be finishing work in the same area. Foamworks coordinates timing with the general contractor so foam goes in after those trades have completed their rough-in but before the insulation inspection, rather than working around active trades in the same cavity, which slows everyone down and increases the chance of foam getting sprayed over something that still needs access.
Meeting Ontario Building Code
New construction has to meet current Ontario Building Code requirements for effective thermal resistance, which vary by climate zone, assembly type, and whether the building is using a prescriptive or performance path. Foamworks confirms the required thickness and configuration for each assembly on a project rather than applying a single standard spec to every build, since code requirements differ between a simple addition and a full new home.

Frequently Asked Questions
As early as possible once rough-in is scheduled. Spray foam crews need a firm window between rough-in inspection and drywall, and last-minute scheduling is the most common cause of delays on this part of a build.
Yes. Plans with wall assembly details and square footage let Foamworks provide a more accurate quote before framing is complete.
Both, depending on the design. Garages sharing a wall or ceiling with living space are commonly insulated for air sealing even when the garage itself isn’t heated.
