Proper attic insulation plays a critical role in maintaining a comfortable temperature in your home while lowering energy bills.
Whether building a new home or upgrading an old one, choosing the right insulation is crucial for energy efficiency. With many options available, understanding attic insulation types can help you decide what’s best for your needs.
In this guide, we’ll break down the different types of attic insulation and help you find the right fit for your attic.
Fiberglass Insulation
Among the different types of attic insulation, one of the most common is fiberglass, available as batts (blankets) or loose-fill. Fiberglass batts are pre-cut to fit between attic joists, while loose fill is blown in using special equipment.
Pros
Fiberglass is affordable, widely available, and easy to install. It’s also non-flammable, making it a safe choice for many homeowners.
Cons
Fiberglass batts can be less effective if not installed correctly, and loose-fill fiberglass requires professional installation for the best results.
Spray Foam Insulation
Spray foam insulation is a modern solution offering excellent coverage in hard-to-reach areas. It expands when applied, sealing gaps and cracks that other insulation types might miss.
Pros
Spray foam offers superior energy efficiency and air sealing, which can greatly reduce heating and cooling costs. It’s also moisture-resistant, helping to prevent mold growth.
Cons
It’s more expensive than other options and requires professional installation.
Cellulose Insulation
Cellulose insulation is made from recycled paper treated with fire-retardant chemicals. It’s usually applied as a loose-fill material, similar to fiberglass, and works well in older homes or homes with irregular attic spaces.
Pros
Cellulose is an eco-friendly option, offering high thermal performance. It’s also more resistant to pests compared to other insulation types.
Cons
Cellulose can settle over time, reducing its effectiveness, and it’s prone to absorbing moisture, which can lead to mold if your attic isn’t properly ventilated.
Rigid Foam Insulation
Rigid foam insulation comes in panels or boards that are installed in attics. It provides a high R-value (thermal resistance) with minimal thickness, making it an efficient option for homes with space constraints.
Pros
Rigid foam provides excellent thermal protection and is moisture-resistant. It also won’t settle or compress over time like other types of insulation.
Cons
Rigid foam is more expensive than fiberglass and cellulose and may require special installation to ensure proper fitting.
Reflective or Radiant Barrier Insulation
Radiant barrier insulation reflects heat away from your attic instead of absorbing it like other insulation types. It’s often used in warmer climates to keep homes cooler during hot summer months.
Pros
This type of insulation works well in hot climates by reducing cooling costs. It’s also lightweight and easy to install.
Cons
Radiant barriers are not as effective in colder climates where heat retention is more important than heat reflection.
Choosing From The Different Types Of Attic Insulation For Your Home
When choosing attic insulation, consider your climate, budget, and whether you’ll hire a professional or DIY. Fiberglass batt insulation is DIY-friendly, while spray foam needs a pro like Anthem Insulation & Home for proper installation.
Your local climate is crucial. In cold regions, higher R-value options like spray foam or fiberglass are better. In hot areas, radiant barriers help keep your home cool.
Find the Best Attic Insulation for Your Home
Understanding the different types of attic insulation is essential for making the best choice for your home. Whether you opt for affordable fiberglass batts or high-performance spray foam, the right insulation can improve your home’s comfort and energy efficiency.
