Treat it as a system decision
Changing the enclosure can affect attic conditions, air movement, drying potential, HVAC sizing or
location, ventilation, humidity, roof assemblies, combustion air, access, and code-required thermal or
ignition protection. Qualified HVAC, building-science, design, or licensed-trade input may be needed for
the final scope.
What to share
Provide property type and use, proposed application area, current insulation, roof and attic configuration,
HVAC location, combustion equipment, moisture or odor history, ventilation, access, and any product
already considered. Include prior reports when available.
Will spray foam lower my energy bill?
No specific savings can be promised from the product name alone. Performance depends on the building,
existing leakage and insulation, HVAC, installation, climate, use, and occupant behavior.
Describe the assembly, HVAC, current insulation, and reason you are considering spray foam.
