Frequently Asked Question
How thick is R49 insulation?
The thickness of R49 insulation is typically around 14 inches. This measurement ensures that the insulation provides high thermal resistance, commonly used in attics and other areas requiring significant insulation to enhance energy efficiency and comfort.
What size insulation is best for 2x6 walls?
Use R-19 or R-21 kraft-faced fiberglass insulation for 2x6 walls to ensure it fits snugly without being too loose or too tightly packed.
How long does it take spray foam to dry?
Spray foam becomes tack-free in 5 to 60 minutes and fully cures in about 8 to 24 hours, depending on the product and conditions.
