Soudal Spray Foam 24Oz Gun Gap Filler
Professional Control. Superior Filling Power.
When you need an airtight, moisture-resistant seal that lasts, the Soudal Soudafoam Gun-Grade Gap Filler is the professional’s choice for efficiency. Designed specifically for use with a professional foam applicator gun, this 24oz canister offers unmatched precision, allowing you to fill gaps, seal penetrations, and insulate cavities with zero waste and maximum control.
Unlike consumer straw foams, this gun-grade formula is engineered for superior structural stability—meaning it won't shrink, collapse, or sag once cured. Whether you are insulating HVAC penetrations, filling large voids in masonry, or sealing around window and door frames, the Soudal Gun-Grade formula creates a durable, high-yield barrier that significantly reduces air infiltration and noise transmission.
