Find out how much insulation your home needs, and what it’ll cost, based on your attic’s square footage. R‑30 is the minimum for most homes in KY, but going higher could boost comfort and energy savings.
In our Kentucky region, with hot, humid summers and chilly winters, your attic is one of the most important areas for energy efficiency. Without proper insulation and sealing, heat moves into your home in summer and escapes in winter, forcing your HVAC system to work harder and costing you more in energy bills.
The state of Kentucky’s residential energy code requires at least R‑30 insulation for ceilings without attic space. (Insulation Institute)
For attics that are accessible and need better protection, energy‑efficiency guides recommend insulation levels of R‑38 to R‑49, or more. (Kentucky Living)
Our practical recommendation is to aim for R‑49 in attics if your current insulation is light or when replacing.
By using our calculator below, you’ll get a clearer idea of how many bags of insulation (and what cost) you’ll need based on your attic’s square footage and the R‑value you choose.
Input your home’s square footage (attic area) and see how many bags you’ll need at various R‑values (R‑13, R‑19, R‑22, R‑26, R‑30, etc.).
Compare our cost out the door (using our standard install pricing of $100 per bag to cover the insulation and our labor).
See the recommended row (R‑30) highlighted, pointing out the baseline you should seriously consider for Kentucky homes.
Use it as a decision‑tool: Is it worth going higher than R‑30 (for comfort, long‑term savings, higher resale value)?
* R-30 is recommended for most attics in Kentucky
Air‑seal first: Before laying down insulation, seal around attic hatches, ducts, plumbing or HVAC penetrations, and any visible gaps. Many energy‑wise homes skip this and lose value in insulation performance.
Ventilation matters: Proper soffit vents plus ridge or roof vents keep moisture and heat from building in the attic, which protects the insulation and your roof’s lifespan. (Together We Save)
Check any existing insulation: If you have old insulation (especially from pre‑1990) it may be uneven, damaged, or contain asbestos. Ask a pro if you’re unsure.
Think long‑term: The upfront cost of better insulation often pays back over time in lower heating & cooling bills, better comfort, and higher resale value.
Insulating your attic properly isn’t just about code compliance, it’s about comfort, energy savings, and long‑term value. This calculator gives you a realistic estimate for your home in Kentucky. Combine that estimate with smart air‑sealing and ventilation, and you’ll be well on your way to a more efficient, comfortable home.
The stack effect is when the air in your home is constantly moving upwards. Your comfortable air in your home is moving up to your attic and escaping.
