Spray Foam Insulation Has One Important Catch
Spray foam insulation has become one of the most popular insulation systems in Ontario because of its energy efficiency, air sealing capabilities, and long-term performance. However, many property owners, builders, and contractors don't realize that exposed spray foam often requires additional fire protection to meet building code requirements.
That's where DC315 thermal barrier coatings come in.
At Muskoka Thermal Coatings, we specialize in DC315 application and thermal barrier coatings for residential, commercial, agricultural, and industrial buildings throughout Muskoka and surrounding areas.
What Is DC315?
DC315 is an intumescent coating designed specifically for use over spray polyurethane foam (SPF). When exposed to high heat, the coating expands and creates an insulating char layer that helps slow the spread of fire.
DC315 is commonly used as:
- A spray foam thermal barrier
- An ignition barrier coating
- A code-compliant alternative to drywall in certain applications
- A fire protection coating for exposed spray foam insulation
The product has been extensively tested and evaluated for use over spray foam insulation systems in Canada and Ontario.
DC315 Ontario Building Code Compliance
In Ontario, exposed spray foam insulation must meet specific fire safety requirements under the Ontario Building Code and National Building Code of Canada.
DC315 has received CCMC evaluation and Ontario Minister's Rulings confirming its compliance as an alternative thermal barrier system over spray polyurethane foam.
This means DC315 may be used in situations where traditional drywall thermal barriers are not practical or desired.
Common examples include:
- Garages
- Shops
- Pole barns
- Crawlspaces
- Attics
- Mechanical rooms
- Commercial buildings
- Agricultural buildings
- Shipping containers
- Exposed industrial ceilings
Why Exposed Spray Foam Requires a Thermal Barrier
Spray polyurethane foam offers exceptional insulation performance, but building codes generally require foam insulation to be protected from occupied spaces by an approved thermal barrier.
Without proper protection:
- Spray foam may fail inspection
- Occupancy approvals may be delayed
- Insurance concerns may arise
- Projects may not meet code requirements
A properly installed intumescent coating for spray foam can help provide the required protection while allowing the foam to remain exposed.
Thermal Barrier Coating vs Ignition Barrier Coating
Many property owners confuse thermal barriers and ignition barriers, but they serve different purposes.
Thermal Barrier Coating
A thermal barrier is intended to delay temperature rise and provide additional occupant protection during a fire event. DC315 is widely used as an alternative 15-minute thermal barrier system over spray foam insulation.
Ignition Barrier Coating
An ignition barrier coating is typically used in areas not normally occupied by people, such as attics and crawlspaces, to reduce the likelihood of ignition. DC315 has also been tested for ignition barrier applications.
The required coating type depends on:
- Building use
- Occupancy
- Foam type
- Location of installation
- Local code requirements
DC315 Applicator Ontario: Why Proper Installation Matters
Applying DC315 is not the same as standard painting.
Proper installation requires:
- Correct wet film thickness
- Proper spray application techniques
- Surface preparation
- Environmental condition monitoring
- Understanding of code requirements and manufacturer specifications
Industry guidance recommends that DC315 be applied by trained and approved installers to ensure compliance and performance.
