A spec sheet in CSI format is available for the Ultra*Ductâ„¢ Gold duct board. This duct board is a rigid board with a new airstream facing that significantly reduces the amount of nuisance dust generated during fabrication, says the company. In addition, the facing adds strength to the board, helps improve handling, and contributes to improvements in the cutting process when both manual and automatic equipment is used, states the company. The board can handle systems operating at twice the velocity as the previous generation of the company's standard duct board, the manufacturer says.
