💡 How does R11 fiberglass batt insulation reduce convective heat loss in framed walls?

You get steady temperature control when blocking airflow in uninsulated stud bays. The dense glass fiber weave traps dead air pockets that stop convective loops from draining your energy bills. This setup works best because:
- Slips right into standard two by four framing without forcing or cutting weird angles
- Maintains structural loft without compressing into load bearing studs
- Uses kraft paper facing to seal seams against outdoor drafts
- Delivers steady performance across seasonal shifts in humidity levels
