East Alabama and West Georgia
Blown-In Attic Insulation
Blown-in attic insulation is a straightforward way to raise attic R-value and cover uneven spaces in existing homes.
Why blown-in insulation works well in attics
Loose-fill cellulose or fiberglass can fill gaps around framing and build a consistent blanket across the attic floor.
Best after air sealing
Before adding depth, it is important to seal common leakage points so the insulation can do its job.
R-value planning
We measure the current insulation depth and recommend the added amount needed for the attic target.
Frequently asked questions
What R-value do I need in my attic in Alabama or West Georgia?
ENERGY STAR explains that R-value measures resistance to heat flow, and Alabama and West Georgia projects commonly fall into warmer climate-zone guidance. Many attic upgrades target the R-38 to R-49 range, based on existing insulation, attic design, and local code. Pro Insulations can measure the current depth and recommend the right target.
Should I air seal before adding attic insulation?
Yes. Air sealing before adding insulation helps stop conditioned air from leaking into the attic and helps the new insulation perform as intended. ENERGY STAR recommends sealing attic air leaks before adding more insulation whenever possible.
How do I know if my attic is under-insulated?
Common signs include high energy bills, rooms that stay too hot or too cold, insulation below the top of the floor joists, dusty drafts, and an HVAC system that runs too often. A quick attic inspection can show the current depth, condition, and likely R-value.
Is blown-in insulation better than batt insulation?
Blown-in attic insulation covers uneven attic floors and odd spaces more evenly than batts in many retrofit projects. Batts can still work well in open framing. The best choice comes down to access, air sealing needs, moisture issues, and the R-value target.
Can insulation be added over old insulation?
Often, yes, if the old insulation is dry, clean, and not contaminated. Wet, moldy, compressed, animal-damaged, or smoke-damaged insulation should be evaluated before adding new material.
Should old attic insulation be removed first?
Old attic insulation should be removed when it is wet, moldy, contaminated by animals, heavily compressed, or blocking needed air sealing work. If it is clean and dry, new blown-in insulation can usually be added over it.
