Spray Foam Scope: Product, Assembly, and Role Checklist
A useful spray foam proposal names the product, application area and intended assembly. It also explains protection, occupancy restrictions and the roles responsible for connected work. Compare those details before treating two proposals as equivalent. A material label or thickness alone does not establish that the complete scope suits the building.
Roofline Spray Foam: HVAC, Ventilation, Moisture Checks
Spray foam at the roofline changes more than insulation location. Review HVAC, ventilation, moisture, combustion equipment and required protection as part of the proposed assembly. Record the current attic arrangement before choosing a product. Qualified reviewers should establish the technical requirements and identify who is responsible for each connected part.
