Quick takeaways
- Relocating ductwork from unconditioned attics to insulated spaces prevents energy loss and mold growth in Texas's extreme heat.
- Replacing fragile cardboard sheathing with durable materials like plywood or OSB significantly enhances a home's resilience against water and air infiltration.
Deep dives
Ducts in Hot Attics
Having ducts in hot attics is a common yet ineffective practice among Texas builders. The extreme heat in attics leads to significant energy loss due to duct leakage, resulting in cooled air escaping into an unconditioned space. This not only raises energy bills but also creates a risk of mold growth due to condensation on cold surfaces. To improve this situation, builders should consider bringing ducts into conditioned spaces, utilizing methods like closed cell foam insulation, which enhances efficiency in both heating and cooling.
