What we do

What is Spray Foam Insulation?

Unlike traditional insulation, spray foam expands to fill gaps, cracks, and cavities, creating an airtight seal that enhances comfort, improves indoor air quality, and reduces energy loss. Once cured, it forms a continuous thermal and air barrier that helps lower heating and cooling costs year-round.

Forms an airtight, long-lasting thermal barrier
What we use

Types We Install

Not sure which spray foam is right for your project?
We’ll assess your space, budget, and building envelope to recommend the best-performing solution.
All spray foam systems are selected based on building type, moisture conditions, and Ontario Building Code requirements.

2 lb Closed-Cell Spray Foam

Closed-cell (2 lb)
A high-density spray polyurethane foam that expands and cures into a rigid insulation layer. It delivers excellent thermal resistance while acting as an air, moisture, and vapour barrier in a single application.

  • High R-value per inch for maximum energy efficiency

  • Excellent air sealing and moisture resistance

  • Adds structural strength to walls and roof assemblies

  • Long service life with minimal performance loss over time

  • Attics and cathedral ceilings

  • Exterior wall assemblies

  • Basements and crawl spaces

  • Garages and commercial buildings

Because of its density and vapour resistance, closed-cell spray foam must be installed correctly to meet building code requirements. Our installations follow CAN/ULC standards and local code guidelines.

Best used for: Attics, exterior walls, basements, crawl spaces, garages, and commercial buildings

½ lb Open-Cell Spray Foam

Open-cell (½ lb)
A low-density, flexible spray foam designed to expand deeply into cavities, creating an effective air seal while allowing assemblies to breathe.

  • Excellent air sealing for improved comfort

  • Effective sound absorption

  • Allows moisture to pass through and dry naturally

  • Ideal for reducing drafts and noise transfer

  • Interior and above-grade walls

  • Sound control and noise reduction

  • Areas where breathability is preferred

Open-cell foam is not a vapour barrier and is not suitable for below-grade or high-moisture environments. We help determine where it is appropriate based on your building and climate.

Best used for: Interior walls, above-grade walls, soundproofing applications

2 lb Pour-In-Place Insulation

Pour-in-place (2 lb)
A closed-cell foam injected into enclosed wall cavities, designed specifically for retrofit and renovation projects.

  • Upgrades insulation in existing walls

  • Even cavity fill with minimal disruption

  • Improves air sealing and thermal performance

  • Ideal for retrofit and renovation projects

  • Finished walls

  • Retrofit projects

  • Hard-to-access cavities

Small access holes are required for installation and are professionally sealed after completion. This system is not used for open framing or attic applications.

Best used for: walls, retrofits, renovations, hard-to-access cavities

3 lb Closed-Cell Roofing Foam

Roofing foam (3 lb)
A high-density closed-cell foam applied to commercial roof systems, forming a seamless, durable insulation layer beneath protective coatings.

  • High compressive strength

  • Seamless insulation layer with no joints

  • Excellent thermal performance

  • Compatible with protective roof coatings

  • Flat and low-slope commercial roofs

  • Warehouses and industrial buildings

Roofing foam systems must be installed with proper surface preparation and coating systems to ensure longevity and warranty compliance.

FAQ – Quick Assist

Answers to the most common questions we hear from homeowners and property owners.

Yes. When installed correctly by trained professionals, spray foam insulation is safe and effective. We use CAN/ULC-S705.1 compliant materials and follow strict installation and ventilation procedures to ensure safe curing and long-term performance.

Spray foam insulation is designed to last the lifetime of the building. Unlike traditional insulation, it does not sag, settle, or degrade over time, maintaining its thermal and air-sealing performance for decades.

In most applications, yes. Spray foam provides a higher R-value per inch, creates an airtight seal, and reduces moisture infiltration. Fiberglass insulates but does not stop air leaks, which can significantly reduce overall efficiency.

Absolutely. Spray foam is commonly installed in older homes during renovations, retrofits, or energy upgrades. It’s especially effective in attics, basements, crawl spaces, and wall cavities where air leakage is common.

Most residential projects are completed in one day. Larger homes or commercial projects may take longer depending on size and scope. Our team will provide a clear timeline during your free estimate.

Yes. All spray foam insulation we install complies with Ontario Building Code requirements, CAN/ULC standards, and CCMC evaluations when applicable.

In most cases, occupants are asked to vacate the space being sprayed during installation and curing. Your installer will advise you on safe re-entry times based on the product and application area.
