Max. 2 to 5 percent total system leakage. Seal Class B – All transverse joints and longitudinal seams shall be sealed.

Is rigid or flexible duct better?

Flex ducts are better for existing trunk-and-branch heating and cooling systems. This is because they’re more versatile and flexible. Metal ducts are more rigid due to the nature of steel, making them ideal to build an entire HVAC system.

Does water pipe need ducting?
