Ducts Inside

Ducts Inside is part of the new Oregon Energy Code. What does that mean and how do you do it?

1. Ducts in unvented attic

2. Ducts in dropped ceiling

3. Ducts in modified truss in attic

4. Ducts deeply buried in vented attic under R-19 minimum insulation

5. Ducts in open web trusses between floors

*A note that up to 5% of the length of the HVAC system can be outside the conditioned space.
*Ducts must be sealed with mastic except at duct connections to equipment requiring future replacement. Then tape is allowed.
