Frequently Asked Questions

What R-value do I need?

R-13 is standard for 2x4 exterior walls. R-19 or R-21 fits 2x6 walls. Attic insulation should be R-30 to R-60 depending on climate zone. Basement walls typically need R-10 to R-15.

What is the difference between rolls and batts?

Rolls are continuous lengths of insulation (up to 40 feet or more) that you cut to size. Batts are pre-cut pieces, typically 93 inches long (standard 8-foot wall height). Rolls cover more area per package and reduce waste in long runs.

How do you estimate property value?

Multiply square footage by local price per sq ft, then adjust for condition, bedrooms, bathrooms, lot size, and improvements. This gives a rough estimate; a professional appraisal is more accurate.

What factors affect home value?

Location, square footage, lot size, condition, age, number of bedrooms/bathrooms, local market trends, school district, and recent comparable sales.
