Steel and concrete roof decks
Closed cell sprayed to the underside of the deck stops condensation and adds R-value without adding weight to the roof. It also seals the flutes on steel deck, which batts never do.

Commercial Spray Foam Insulation in Guelph and Waterloo Region
Super Sprayers sprays commercial buildings across Guelph, Kitchener, Waterloo and Cambridge for property managers, general contractors and business owners who need the job done once and documented properly. Since 2018 our crews have insulated retail units, offices, warehouses and multi-residential buildings alongside the homes and farms that make up the rest of our 800-plus jobs. Our installers are CUFCA certified, and every commercial install is recorded to the CAN/ULC-S705.2 installation standard.
Commercial buyers care about different things than homeowners do, and price per square foot is only one of them. You need a crew that shows up on the date in the schedule, works around tenants who still have a business to run and hands over WSIB clearance, insurance certificates and product data without being chased. You also need foam that satisfies the Ontario Building Code where it meets fire separations and exposed interior space.
We handle the insulation and the fire protection that goes over it. Our applicators are Carboline certified for structural steel fireproofing, and the company carries Industrial Fireproofing Insured Company coverage. That means one contractor, one schedule and one point of responsibility for foam, thermal barrier coatings and the paperwork your inspector will ask to see, whether the job is a single retail unit or a full warehouse roof deck.

Commercial Buildings We Insulate
Most commercial work in our area falls into a handful of building types. Each one has a common problem that spray foam solves.
| Building type | Common application |
|---|---|
| Offices and professional units | Perimeter walls and roof decks during fit-outs |
| Retail plazas | Exterior wall cavities and demising walls between units |
| Restaurants | Walk-in coolers, kitchen walls and roof decks |
| Warehouses | Steel roof decks and walls to stop condensation |
| Multi-residential | Rim joists, roofs and sound between suites |
| Places of worship | High ceilings and older masonry walls |
| Real estate turnovers | Upgrades between tenants to lease a unit faster |
Spraying Around Your Business Hours
Most commercial spaces can't close for a week, so we plan the spray around your operating hours. Our crews work until 9:00pm Monday to Saturday and from 9:00am to 6:00pm on Sundays. That leaves room for evening or weekend sprays in occupied buildings.
Before we start, we agree on a ventilation plan, a sealed work zone and a re-occupancy time based on the foam manufacturer's instructions. We can draft the tenant notice for you. Air handlers serving the work zone are shut down or isolated so fumes don't travel through the building.
Thermal Barriers and Fire Separations in Commercial Space
Foam plastic insulation left exposed inside a building needs a thermal barrier under the Ontario Building Code, and Part 3 buildings have stricter fire separation rules than houses. Where drywall isn't practical, we apply an intumescent coating such as DC315 at the thickness its listing requires. We record the wet-mil readings so the inspector sees the numbers.
Because we also apply structural fireproofing, we can plan both layers together instead of waiting on a second trade. Details are on our fireproofing and thermal barrier page.
Paperwork for GCs and Property Managers
Every commercial job comes with a closeout package. Ask for any of these with your quote.
- WSIB clearance certificate, current for the project dates
- Certificate of insurance naming the owner or GC where required
- CAN/ULC-S705.2 daily work records, including field density and adhesion checks
- Product data sheets and safety data sheets for each foam and coating
- CCMC evaluation listings for the foam systems used
- Thermal barrier thickness readings and product listing references
- Photos of the completed work before it is covered
- Written labour warranty for the scope of work
Roof Decks, Walls and Below-Grade Space
The same building often needs different foam in different places. These are the three we see most.
Exterior and demising walls
Closed cell in steel stud or wood walls gives the most R-value in a thin cavity. Open cell is useful on interior demising walls where sound matters more than R-value.
Basements and below-grade rooms
Closed cell on foundation walls controls condensation in storage rooms, parking levels and basement suites. It meets the vapour control requirement at about 2 inches.
Commercial Pricing and Scheduling Factors
Commercial quotes depend less on square footage alone and more on how the space is reached and protected. The biggest factors are:
- Total board feet, meaning area multiplied by thickness
- Working height and whether a scissor lift or boom lift is needed
- Containment and masking around equipment, stock or finished areas
- After-hours or weekend work to keep the business running
- Thermal barrier or fire coatings over exposed foam
Send drawings and a rough schedule and we'll price each of these separately so you can compare line by line.
Commercial Project Questions
Can you spray while tenants occupy the building?
Often yes, if the work zone can be sealed and ventilated and the air handling isolated. We plan the spray for evenings or weekends and set a re-occupancy time before tenants return.
Do you provide documents for the building inspector?
Yes. You get S705 daily work records, product listings and thermal barrier readings, which are the documents inspectors ask for most often.
Can you apply the thermal barrier coating too?
Yes, we apply intumescent thermal barrier coatings over our own foam, so there's no second trade to schedule. See our fireproofing page for how it works.
