Spray polyurethane foam (SPF) is an optional spray foam insulation in our Star Building System
For Inco Brand Buildings only, spray foam (SPF) is avalible
Closed-Cell Spray Polyurethane Foam (SPF)
From concept to completion, Inco handles the entire project from start to finish including spray foam insulation.Â
Closed-cell Spray Polyurethane Foam (SPF): Closed-cell spray polyurethane foam (SPF) is the type of closed-cell insulation commonly used for metal buildings; it contains polyurethane and/or polyisocyanurate materials. When applied, an air- and moisture-tight seal is created on metal surfaces by this type of foam due to its high R-value, structural reinforcement, and high R-value. Closed-cell spray foam insulation is denser, more expensive, and can provide more insulation in a thinner layer.
Typical Spray Foam Insulation Costs
The estimated cost to insulate a 50x100x16 (red Iron, I-Beam Steel) metal building with Closed-Cell Spray Polyurethane Foam (SPF) is approximately $22,000 plus fees. R-42 value is proposed in the roof/ceiling. R-24 value is proposed in the walls.
Thermal, Air, Water, Vapor Barrier Seal
Thermal, Air, Water, Vapor Barrier Seal: Applied as a single component, closed-cell spray polyurethane foam can provide a complete air, water, and vapor barrier for metal buildings. Spray polyurethane foam (SPF) provides a thermal barrier, is dense and water-resistant, and creates an airtight seal by filling gaps and cracks.
Codes in North Carolina, Spray Foam Insulation
Application: For spray foam insulation, North Carolina building codes and energy codes address fire safety and energy efficiency, and require specific flame spread and smoke-developed indexes, an ignition barrier to protect it from the interior, and proper application techniques to control moisture.
The R-Value of Spray Form Insulation
R-Value Assemblies: The total R-value for Ceiling assemblies and Wall assemblies.
R-value per inch of thickness for (SPF): *R-6 to R-6.5Â Â *Base Calculations* The following foam manufacturers provide higher R-value densities per inch of thickness: UPC Foam Products offers high R-Value Foam Products
R-Value Walls (SPF):Â Closed-cell spray foam has an R-value of approximately R-6 to R-6.5 per inch thickness, approximately 2.5 inches of thickness would be needed to meet the R-15 [Wall Assembly] requirement.
R-Value Ceilings (SPF):Â Closed-cell spray foam has an R-value of approximately R-6 to R-6.5 per inch thickness, approximately 6.5 inches of thickness would be needed to meet the R-38 [Ceiling Assembly] requirement.
Installer Certification for Spray Foam Insulation
Certification by Foam Installer: The spray foam installer must provide certification detailing the type of foam installed, the R-value, thickness, and density of the installed foam to demonstrate energy code compliance, and installed thickness for the areas covered.
REScheck | Compliance | Spray Foam Insulation
REScheck software applications help builders, designers, and contractors demonstrate compliance with energy codes, and create compliance reports for code officials.
REScheck: REScheck software app is used to calculate a buildings’ U-factor x Area (UA) values. The spray foam installer must provide precise R-values and thickness information for the REScheck report to be accurate.Â
Code Compliance. Before work is started – prior to spray foam installation: Consult the local presiding Building Inspection Department about all related local energy codes, building codes, and thermal code compliance for the intended use and building type application.
