Hot air rises. To keep warmth inside your home, you need an effective thermal barrier in the attic. Unfortunately, not all attic insulation is made equally. How do you know whether your insulation is doing the job?
New Jersey Siding & Windows, Inc., provides attic insulation and other home improvement services throughout northern New Jersey. Here, our team presents a guide to attic insulation R-values to help you understand insulation ratings and know when it’s time to upgrade.
Key Takeaways
- Attic insulation R-value is a measurement of how effectively the insulation blocks heat transfer.
- The modern standard for New Jersey homes is an R-value between R-49 and R-60. While new homes meet this standard, many older homes do not.
- Signs that it’s time to replace your insulation include drafts, inconsistent climates between rooms, moisture problems, ice dams, and rising energy bills.
What Are Attic Insulation R-Values?
Attic insulation R-value is a rating system for insulation efficiency. It’s calculated by dividing the insulation’s thickness by its thermal conductivity coefficient, or how quickly it conducts heat. The result is a number that tells you how effectively your insulation does its job. The higher the R-rating, the more heat your insulation can block.
R-values are affected by the insulation’s material, thickness, and age. Different materials block heat more efficiently than others. Thicker insulation allows heat to travel farther, increasing its R-value, but damage and age-related deterioration reduce its effectiveness.
What R-Values Are Typical in New Jersey Homes?
Not every home needs the same R-value. The optimal R-value depends on your local climate, with colder regions requiring more effective insulation to keep you comfortable at home. The typical New Jersey home is built with attic insulation R-values between R-49 and R-60 to provide a robust barrier against the typical winter conditions.
Modern energy codes require new homes to be built within this R-value range. If you own an older home, however, then it may have been constructed before the current energy codes were established. It may also have aged insulation that has broken down due to time, moisture intrusion, and pests. As a result, many older New Jersey homes don’t meet the same standards for thermal efficiency. You may be losing heat through your attic, resulting in drafts and rising energy bills.
How Do You Know It’s Time to Upgrade Your Insulation?
Checking your insulation can be tricky, especially if you don’t have convenient access to the attic. Fortunately, there are other ways to tell when it’s not doing its job. The following signs point to inadequate attic insulation:
- Some rooms are warmer or colder than others.
- You feel cold drafts on the upper floor of your house.
- Ice dams and large icicles form on your roof.
- You have leaks, moisture problems, or a moldy smell.
- Your energy bills are increasing for no clear reason.
If you experience any of the above issues, then it’s time to upgrade your home. You can start by air sealing to block any gaps where air moves between your home and the outdoors. This step can be a cost-effective way to improve your thermal performance. If air sealing doesn’t help, then you should consider upgrading your insulation for long-term energy savings.

Attic Insulation R-Values FAQ
What is an insulation R-value?
R-value is a measurement of your insulation’s ability to resist heat transfer. It measures how much heat moves through the material. R-value ratings vary depending on the type, density, and thickness of your insulation, with higher ratings indicating more effective insulation.
What attic insulation R-values are typical in New Jersey homes?
Current New Jersey energy codes require new homes to be built with R-values between R-49 and R-60. Older homes often have much lower ratings because they were built with less insulation or because their existing insulation material has degraded.
How can homeowners tell if an insulation upgrade is worth it?
If you live in an older home with poor insulation, then upgrading may provide energy bill savings and significant improvements in your comfort. Here are some signs that an upgrade will be worth it:
- Uneven temperatures between rooms
- A cold, drafty feel on the upper floor
- Ice dams forming on the roof
- Moisture, mold, and mildew in your home
- Increasing energy bills
What home improvements usually matter most before adding insulation?
Before adding insulation, start by air sealing your home. Air sealing is the process of locating and closing up all of the nooks and gaps where outdoor air can enter your home. This step can dramatically improve your home’s thermal efficiency without requiring new insulation.
