Muskoka Thermal Coatings
DC315 Thermal Barrier Specialists · Muskoka, Ontario
The Coordination Gap That Causes Inspection Delays
If you're a builder or general contractor working in Muskoka, you've almost certainly run into this: spray foam goes in, the project moves forward, and then at framing inspection the inspector wants to see a thermal barrier on the exposed foam.
This guide is for contractors who want to get ahead of that problem.
Understanding the Trade Sequence
DC315 thermal barrier coating is a distinct trade from spray foam insulation. The spray foam contractor installs the insulation. A separate specialist applies the thermal barrier coating.
If you're managing a build where spray foam is specified, the DC315 application should be a named line item in your trade schedule — not an afterthought.
The Optimal Sequencing for New Builds
- Spray foam installation — insulation contractor completes the application
- Cure time — typically 24 hours minimum before DC315 can be applied
- DC315 application — thermal barrier specialist coats all required surfaces
- Dry time — 24-48 hours depending on conditions
- Framing/insulation inspection — inspector reviews the completed thermal barrier
- Proceed with other trades — mechanical, electrical, drywall, etc.
What to Include in Your Scope of Work
When coordinating with a DC315 applicator, provide:
- Approximate foam surface area
- Space type and access constraints
- Target inspection date
- Documentation requirements
Common Coordination Issues
'The spray foam contractor said they'd take care of it' — Unless DC315 is explicitly in the spray foam scope and priced accordingly, assume it's not included.
'We'll do it after the other trades finish' — Applying DC315 around installed mechanical and electrical is significantly more complex. Do it first.
'We didn't know it was required' — If spray foam is going into an occupied or accessible space, assume a thermal barrier is required.
Pricing Reference for Construction Budgets
Typical DC315 pricing: $2.50 to $3.50 per square foot, minimum project fee of $1,500.
- Small crawlspace or partial basement: $1,500-$2,000
- Full basement application: $2,000-$4,500
- Large or complex project: $4,500+
Pro Tip: Add a DC315 line item to your standard spray foam spec sheet. It sets the right expectations with clients from day one.
