  • High air velocity duct board having minimal turbulence
    Patent number: 5783268
    Abstract: A rigid fiber glass duct board for air ducts in which the air contacting surface is a mat facing formed from a saturated polyester/glass mat which presents a smooth surface to flowing air and hence avoids surface degradation at very high air velocities. A method of forming such a board is also disclosed.
