Perfect for attics, basements, crawl spaces, rim joists, garages, workshops, tiny homes, and large residential or commercial insulation upgrades.
Why Choose Two Component Spray Foam?
- Professional Performance: Dual-cylinder canisters maintain a precise chemical ratio for uniform cell structure and consistent foam density.
- Superior R-Value (6.27 per inch): Closed-cell formulation delivers outstanding thermal resistance with minimal thickness; ideal for cold climates and high-efficiency homes.
- ASTM E-84 Class A Fire Rating: Certified for minimal smoke and flame spread, meeting building code requirements for residential and commercial use.
- Long-Term Durability: Creates an airtight, moisture-resistant, pest-resistant, and structurally rigid barrier.
- Rapid Cure Time: Tack-free in 30 seconds, full cure in 24 hours.
- Eco-Friendly Formula: Low-VOC, HFC-free, and manufactured with reduced Global Warming Potential (GWP).
Where to Use Two Component Spray Foam?
Closed-cell two-component spray foam kits are ideal for:
- Residential & Commercial Insulation: Perfect for new construction, renovations, and energy-efficiency upgrades requiring high-performance insulation.
- Wall Cavities & Ceilings: Fills wall cavities, gaps, cracks, and framing areas.
- Electrical, Plumbing & HVAC Areas: Safely insulates around penetrations without shrinking, overheating, or losing adhesion.
- Basements, Foundations & Crawl Spaces: Controls moisture, condensation, and cold air infiltration; great for rim joists and thermal bridging control.
- Attics, Garages & Workshops: Improves temperature stability and prevents air leakage in both hot and cold climates.

How to Apply Two Component Spray Foam
- Step 1: Preparation: Wear protective coveralls, gloves, goggles, and a respirator. Ensure proper ventilation and keep both canisters at 75–85°F (24–29°C). Shake thoroughly for a few minutes.
- Step 2: Setup: Connect the color-coded hoses (blue = polyol, red = isocyanate), tighten with the provided wrench, and test the spray pattern. Lightly lubricate the gun tip with petroleum jelly.
- Step 3: Application: Spray from 6"–22" (15–55 cm) in smooth passes. Apply foam in 1–2 inch layers, letting each layer expand and cure for several minutes. Replace the nozzle if paused for more than 30 seconds. Allow the foam to fully cure before trimming or finishing.
