  • Seal out drafts, moisture, and pests with the Würth 12 oz Expanding Foam Sealant. This professional-grade insulating spray foam is designed for tradespeople and DIYers, offering long-lasting results. It is engineered to fill gaps and cracks up to 1 inch wide, bonding to wood, concrete, brick, drywall, and most common building materials. The foam creates a durable seal that resists shrinking and sagging. Once cured, it forms an airtight, water-resistant, weatherproof barrier, reducing heating and cooling costs by eliminating air leaks around windows, doors, pipes, and wall penetrations. It also dampens sound transmission and blocks common pest entry points. The foam is perfect for sealing window and door frames, plumbing and electrical penetrations, rim joists, foundation cracks, attic and basement air gaps, and structural voids. Suitable for both interior and exterior applications year-round, even in low temperatures. The fast-curing formula goes tack-free in 10 minutes and can be cut, sanded, trimmed, or painted after 60 minutes, allowing for rapid project completion. With a straightforward application process, simply shake the can, attach the included straw, and spray upside down for precise coverage.
