Attic Insulation R-Value Guide for Texas Homes

January 25, 20266 min read

What R-Value Means

R-value measures how well insulation resists heat flow — higher R-value = more insulating power. It depends on material type, thickness, and density.

For attics in Dallas-Fort Worth (DOE Climate Zone 3), the current recommended range is R-38 to R-60, roughly 12 to 18 inches of blown fiberglass or cellulose.

How to Check Your Current Level

Measure the depth of insulation between the attic joists with a ruler. Fiberglass batts and blown cellulose average R-3 to R-4 per inch, so 10 inches of loose fill = roughly R-30.

If your insulation is compressed, wet, or has settled to under 8 inches, you're losing significant conditioned air through the ceiling.

Best Insulation Types for Texas

Blown-in cellulose: cost-effective, made from recycled paper, treated for fire and pests. Excellent for retrofit installations.

Blown fiberglass: mold-resistant, non-combustible, longer lifespan.

Spray foam: highest R-value per inch (R-6 to R-7), seals air leaks, but higher cost.

Radiant barriers: reflect radiant heat before it reaches insulation — highly effective in Texas summers.
