Foam sealant sprays are designed to insulate, seal, and adhere to the area sprayed. Air leaks in the home can be costly, so when an airtight, weather resistant seal is required, expanding foam sealants can block air leaks, moisture, and pests. A wide selection of high-quality products are available. Low expansion foam is offered for smaller gaps and denser foams are offered to seal bigger gaps. Additional options include features such as ultraviolet resistance, fire retardancy, or mildew resistance. Most foam sealants are flexible and resistant to cracking. Accessory products are also offered including applicator guns and cleaning solvents to remove foam sealant in the case of spills. Select products qualify for a bulk order discount.
