Upgrading your home's insulation is one of the cheapest ways to save on energy. In Arizona, R-38 is recommended for your attic. R-value measures the thermal resistance of a material. Meaning the more material, the greater its ability to resist heatflow.
The following are required for an install to be effective:
- Alignment to air barrier
- Uniformity in thickness
- No Gaps, voids, or compressions
- Secured in place and protected from wind intrusion
