Installation is as easy as any other foam tape. It’s also self-extinguishing, so it won’t ignite in a fire. In addition to the traditional places where you’d use foam tape-think around doors, windows, rooflines, soffits, gaps between the house and a covered patio-Expanding Foam Tape works very well around hard-to-seal, uneven surfaces, such as areas where concrete meets wood. “You can use it in any application where you’d use foam tape and it will do a better job because it’s so much denser.” “Our Expanding Foam Tape has excellent insulating and sealing properties and it’s lightweight and stable, but incredibly dense,” Sanders says.

As it expands, the tape conforms to the space, creating a watertight seal that’s resistant to bugs and vermin and can withstand temperatures between -40° F to 212° F. But Expanding Foam Tape is compressed and can grow to fill cracks anywhere from ¼-inch to 1-inch wide. With a traditional foam tape, you’d have to cut individual pieces of tape and layer them to fill larger gaps. So, for example, if you have a 150-year-old home with the original door, you may have a large gap at the top of the door frame and a smaller gap near the floor because the house has settled over time. They couldn’t find a sealant that could completely seal the range of gaps in corrugated roofing,” he explains.įrost King’s Expanding Foam Tape meets that need by doing exactly what the name implies: it expands to fill uneven spaces. “This product came about because people were having trouble building pole barns.
