OSI QUAD Foam Closed-Cell Insulating Sealant Foam, 21.1 oz Can, Straw and Gun-Grade
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.

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.
