Foam tape has a foam substrate that conforms to irregular surfaces and provides an insulating barrier between two surfaces. The foam acts as an insulator against noise, pests, drafts, and absorbs vibration. It is used for weatherstripping, gasketing, mounting, and to create space between two items that are next to each other. Foam tape has a pressure-sensitive adhesive and can be single- or double-sided. It can be indoors and outdoors.
