Older homes come with undeniable charm, but they often lack modern energy efficiency. One of the most significant factors that affects both comfort and energy bills in these homes is insulation—or, more often than not, the lack thereof. Whether you're trying to cut down on heating and cooling costs, improve comfort, or increase the value of your home, upgrading insulation is essential for older properties.
In this guide, we’ll explore the best insulation options for older homes and how they can make a noticeable difference. If you're ready to learn more about the benefits of spray foam insulation for your home or discover other effective insulation types, this post is for you.
Why Older Homes Need Better Insulation
Older homes were built in an era when energy efficiency wasn’t a major concern. As a result, these homes often have little to no insulation, leading to issues such as:
High Energy Bills: With inadequate insulation, your home requires more energy to maintain comfortable temperatures, driving up heating and cooling costs.
Uncomfortable Drafts: Older homes can be drafty due to poor insulation, making it hard to keep your home consistently warm in the winter and cool in the summer.
Moisture Problems: Without proper insulation, older homes are more susceptible to moisture problems, which can cause mold and rot over time.
If you live in an older home and are experiencing any of these issues, it’s time to discover how an experienced insulation contractor can help you to save on energy bills and enhance your home's overall comfort.
Top Insulation Options for Older Homes
Upgrading the insulation in your older home can significantly improve energy efficiency and comfort. Here are some of the best insulation options suited for older properties:
1. Spray Foam Insulation
Spray foam insulation is one of the most effective solutions for older homes. It works by expanding upon application, filling gaps, cracks, and other hard-to-reach areas where air might be leaking. This type of insulation provides a superior air seal, making it perfect for older homes with uneven surfaces and many small gaps.
Why It’s Ideal for Older Homes: Spray foam insulation creates an airtight barrier, which helps to prevent drafts and moisture intrusion. Older homes often have irregular gaps, and spray foam can seamlessly fill these areas.
Energy Efficiency: With one of the highest R-values (a measure of thermal resistance), spray foam insulation offers exceptional energy efficiency, helping to keep your home warmer in the winter and cooler in the summer.
Longevity: Spray foam is highly durable and can last for decades without needing replacement. Find out why spray foam insulation is a great choice for eco-friendly homes and those looking for a long-term solution.
2. Fiberglass Batt Insulation
Fiberglass batt insulation is a popular choice for older homes because it’s affordable, easy to install, and still provides effective thermal resistance. This type of insulation comes in large rolls or pre-cut panels, making it suitable for walls, floors, and attic spaces.
Cost-Effective: Fiberglass is one of the most cost-effective insulation options available, which makes it appealing to homeowners looking for an affordable upgrade.
Ease of Installation: If your older home has open walls or accessible attic spaces, installing fiberglass batts can be relatively straightforward. It’s also one of the more budget-friendly options.
Considerations: While fiberglass is effective at reducing energy loss, it doesn’t create an airtight seal like spray foam. It’s best used in combination with air-sealing measures for optimal performance.
3. Cellulose Insulation
Cellulose insulation is another excellent option for older homes. Made from recycled paper and treated with fire retardants, cellulose is an environmentally friendly option. It’s often installed by blowing the material into walls or attic spaces, where it effectively fills in cavities.
Eco-Friendly: For homeowners looking for a greener option, cellulose is an ideal choice. It's made from up to 85% recycled materials and reduces waste in landfills.
Dense and Effective: Cellulose is dense, which means it’s excellent at blocking airflow and adding thermal resistance to your home. It’s perfect for insulating older homes that need a little extra help keeping temperatures steady.
Application: Because it’s blown into place, cellulose can fill tight cavities and spaces in walls, making it a practical choice for retrofitting older homes with minimal disruption.

4. Mineral Wool Insulation
Mineral wool insulation, also known as rock wool, is a high-performance insulation material that is fire-resistant and has excellent soundproofing qualities. It’s often used in homes where additional fire protection is desired, or where soundproofing between floors and walls is important.
Fire Resistance: Mineral wool can withstand temperatures up to 1,800 degrees Fahrenheit, making it a great option for safety-conscious homeowners.
Soundproofing: In addition to its thermal resistance, mineral wool offers significant soundproofing benefits, which can be particularly useful in older homes with thin walls.
Durability: Mineral wool is highly durable, resistant to moisture, and doesn’t degrade over time. It’s a solid choice for older homes that need long-lasting insulation.
Considerations When Insulating Older Homes
Upgrading insulation in an older home requires a strategic approach. Here are some important factors to consider before selecting the best insulation type for your project:
1. Air Sealing
Before installing new insulation, it’s crucial to address air leaks. Insulation works best when combined with proper air sealing to prevent drafts and leaks. For older homes, this step is especially important because of the likelihood of gaps in walls, around windows, and along the foundation. A professional contractor can help assess your home for air leaks and ensure they are sealed before installing insulation.
2. Wall Accessibility
Depending on the age and design of your home, access to walls and attic spaces might be limited. Retrofitting insulation into walls can sometimes require cutting small holes for blown-in insulation or spray foam. In other cases, insulation can be applied from the exterior during renovations.
3. Budget
While spray foam offers the best overall performance, it’s more expensive than fiberglass or cellulose. Consider your budget when choosing insulation, but remember that investing in higher-quality materials will pay off in energy savings and improved comfort over time.
4. Moisture Control
Older homes are often prone to moisture issues, so it's essential to choose insulation that also acts as a moisture barrier. Spray foam and mineral wool, for example, can help prevent mold growth by reducing moisture infiltration.
FAQ
1. What is the best insulation for older homes?
The best insulation depends on the specific needs of your home. Spray foam offers superior air sealing and energy efficiency, while cellulose is a good eco-friendly option. Fiberglass is a more affordable solution that can still offer significant improvements in energy efficiency.
