OSI QUAD Foam is a high-yield, quick-setting closed-cell insulating foam sealant in a 21.1 oz can (CN). Its high closed-cell ratio blocks air and moisture, delivers an R5 insulation value, and applies in temperatures as low as 14 degrees F for year-round use in all regions.

Key Features:

• Closed-cell technology: High ratio of closed-cell structures provides an ideal barrier to air and moisture.
• R5 insulation value: R5 insulation value helps inhibit heat transfer.
• Cold-weather application: Can be applied in temperatures as low as 14 degrees F.
• Quick-setting formula: High-yield, quick-setting foam speeds up sealing work.
• All-season performance: Works in all regions during high summer heat and extreme winter lows.
• Flexible durability: Strength and flexibility let it withstand years of seasonal expansion and contraction.

Coverage & How Much You Need:

The manufacturer describes QUAD Foam as high-yield but does not state a specific square-foot or linear-foot yield; plan usage by bead size and gap volume. Estimate from the 21.1 oz can capacity and the bead dimensions you will dispense.

Fit and Compatibility:

QUAD Foam is designed for sealing building gaps and penetrations where air and moisture control plus R5 insulation are needed; pair with OSI sealants and caulks for perimeter and exterior finishing. Straw and gun-grade dispensing options let it suit both small repairs and production work.

Expert Verdict Reviewed by the SuperArbor Pro Desk

QUAD Foam is a good pick for subfreezing and shoulder-season sealing where standard foams fail, and its flexibility suits joints that move with the seasons. Use gun-grade cans with a dispenser for production framing and window work, and straw cans for touch-ups. Fill gaps in layers rather than overpacking, since expanding foam can bow frames if applied in excess.

Expanding foam sealants are flammable during application and bond to skin; wear gloves and eye protection, ventilate the work area, and keep away from ignition sources until cured.
