Basement Spray Foam and DC315 - London, ON

This unfinished and uninsulated basement in London needed some spray foam! We also covered the spray foam with DC315 (thermal barrier paint)- but why? The thermal barrier is required for occupied spaces or service spaces (attics and crawlspaces) that house any appliances i.e. furnace, HRV, HWT. The exemption exists only in service spaces that are strictly only running ductwork, piping or wiring. If the area is served by stairs or has access and is used for storage, these areas are considered livable and therefore require the exposed spray foam to be covered with a product like DC315, or with drywall. 

This is why spaces with drywall over the spray foam insulation do not require DC315 paint.
