GAF SPF Flashing Foam, Two-Component Closed-Cell Low-Pressure Polyurethane Spray Foam Kit, R-6.6 per Inch
Regular price $730.00GAF SPF Flashing Foam, Two-Component Closed-Cell Low-Pressure Polyurethane Spray Foam Kit, R-6.6 per Inch
GAF SPF Flashing Foam is a two-component, closed-cell, low-pressure, solvent-free polyurethane spray foam designed to fill and insulate penetrations and voids. It provides an unaged R-value of 6.6 per inch and 13.2 at 2 in. thick, and forms a continuous air barrier. The boxed kit suits cold storage and tilt-up wall applications from flat roof to parapet wall.
Key Features:
- Closed-Cell Foam: Two-component, closed-cell, low-pressure, solvent-free polyurethane foam spray.
- Fill & Insulate: Expands in penetrations, gaps and cracks to insulate and prevent air leakage.
- Tested to ASTM E84: Tested to ASTM E84 with an FSI of 5 and SDI of 450 at 2 in. thickness.
- Strong R-Value: Provides R-6.6 at 1 in. thick and R-13.2 at 2 in. thick (unaged).
- Temperature Indicator: Patented dispensing unit changes color to show chemical temperature is above the required 70°F tank install temperature.
- Continuous Air Barrier: Excellent adhesion creates a continuous air barrier that completes the building envelope.
- Low-GWP Formula: Contains low-GWP propellants and no HFC.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Low-pressure two-component foam kits are well suited to flashing penetrations and cavity voids where large rigs are impractical. Check the dispensing unit's temperature indicator before spraying, since cold chemicals impair foam quality and yield. Spray in thin lifts at detail scale so the closed-cell foam cures evenly and does not over-expand beyond the void.
Two-component spray foams require appropriate PPE (gloves, eye protection, respirator) and ventilation per the product safety data sheet; the kit is classified HAZMAT for shipping.
Order the GAF SPF Flashing Foam kit to fill, insulate and air-seal roof penetrations with closed-cell polyurethane.
