Gravenhurst Builds, Renovations, and the Thermal Barrier Question
Gravenhurst grows a little every year. Commuter homes, retirement builds, and cottage upgrades around the south end of Lake Muskoka all lean on spray polyurethane foam for insulation performance through a real Muskoka winter.
The catch: building codes generally require exposed spray foam to be protected from occupied spaces by an approved thermal barrier. If your plans leave foam exposed — a basement, garage, crawlspace, or mechanical room — DC315 intumescent coating is often the cleanest path. It's sprayed over the cured foam and expands into a protective char layer under high heat, helping slow fire spread without the need for drywall in many applications.
What We Service in Gravenhurst
- Full basements and basement ceilings in new and existing homes
- Garages, workshops, and outbuildings
- Cottage and boathouse-adjacent renovations around Lake Muskoka
- Crawlspaces and mechanical rooms
- New construction for builders and their spray foam subs
Builders: We're Your Coating Sub-Trade
Gravenhurst builders coordinate insulation subs across multiple jobs. We slot in as the DC315 applicator — after cure, before inspection — with clear documentation for your project file and consistent film thickness every time.
The Process
- Project review and clear written quote
- Scheduling around your foam installation and inspection dates
- Surface preparation and masking
- Spray application per manufacturer specification
- Final walkthrough with you or your site supervisor
