Can I use black fiberglass tape for insulation purposes?

Black fiberglass tape can be used for insulation purposes, particularly for sealing and reinforcing insulation materials. It is often used to wrap around pipes, ducts, and other surfaces to provide an additional layer of protection against heat loss or cold. However, it's important to note that fiberglass tape is not a primary insulating material but rather a supplementary one. It's also crucial to ensure that the tape is suitable for the temperature range of the application and that it's properly secured to prevent air and moisture infiltration.
