IXIRPRO Spray Foam Insulation Can is a 30 oz / 850 g gun-grade polyurethane foam for compatible air-sealing and insulation work. It is intended for controlled application with a compatible foam gun and project-specific preparation. Coverage, expansion, curing and thermal performance depend on layer thickness, temperature, humidity, substrate condition, application technique and waste.
Quick answer: Use this can only where the product label and applicable building requirements permit polyurethane foam. Confirm the required R-value, fire-protection layer, clearances, ventilation and substrate suitability before starting; the foam alone does not make an assembly code compliant.
What This 30 oz Spray Foam Can Is Designed For
The can dispenses expanding polyurethane foam through a compatible applicator. The gun helps control output, but the selected foam, assembly design and local requirements determine whether the product is suitable for a rim joist, wall cavity, roofline, metal surface, window or service penetration. Do not use it as structural reinforcement, a universal waterproofing system or a firestop unless the current product documentation specifically approves that use.
Coverage and Thickness Planning
The current product page presents pack estimates based on a stated coverage per can. Treat these numbers as planning estimates rather than guaranteed finished area. Actual yield can decrease because of thicker passes, overspray, irregular cavities, cold material, poor substrate preparation, start-and-stop losses or application waste.
Planning variable
Why it changes yield
Applied thickness
Doubling the thickness approximately halves the area available from the same volume before waste.
Surface profile
Rough, open or irregular cavities require more material than a flat test surface.
Temperature and humidity
They affect expansion, cell formation, curing and the consistency of the spray pattern.
Technique and waste
Overspray, pauses, blocked tips and unplanned trimming reduce usable yield.
Use the IXIRPRO spray foam calculator as an initial estimate, then include a reasonable waste allowance and verify the current label's coverage basis before ordering.
Substrate and Project Suitability
• Remove dust, oil, loose paint, frost and standing moisture before application.
• Protect finished surfaces and test adhesion on an inconspicuous area.
• Check clearances around heat sources, flues, chimneys, recessed fixtures and electrical equipment.
• Do not spray over active leaks, wet or deteriorated materials without correcting the underlying cause.
• For roof decks, unvented attics, occupied spaces and code-regulated assemblies, confirm the design with a qualified professional or authority having jurisdiction.
