Choosing the right insulation is critical for maintaining a comfortable, energy-efficient home. In this article, we compare three of the most popular wall insulation options, Fiberglass, Cellulose, and RetroFoam and explain why RetroFoam is the top choice for homeowners looking for superior performance and long-lasting comfort.

Fiberglass Batt Insulation

Fiberglass insulation is one of the most widely recognized types of insulation, often characterized by its fluffy, pink appearance. It has been a staple in home insulation for decades due to its affordability. However, fiberglass comes with its own set of drawbacks.

• Composition: Made from spun glass fibers, this material is often 50-70% recycled content, which can appeal to eco-conscious homeowners.
• Installation: Fiberglass batts are relatively simple to install, but they must be carefully fitted around windows, doors, and electrical outlets to avoid leaving gaps.
• Health Concerns: Disturbing fiberglass can release small particles into the air that can irritate your skin and respiratory system. Although unlikely to affect homeowners, continuous exposure may pose risks to installers and construction workers.
• Performance: While fiberglass provides decent insulation, it is less effective at preventing air leaks compared to other options, especially when installed improperly. Over time, it can also settle and lose effectiveness, leading to drafts and higher energy bills.

Dense Packed Cellulose Insulation

Cellulose insulation is an eco-friendly choice, typically made from recycled newspaper treated with fire retardants. It has been around for over a century and continues to be a popular choice for its lower cost and environmental benefits.

• Composition: Cellulose is plant-based, using materials like recycled paper and cardboard. This makes it a more sustainable option compared to synthetic materials like fiberglass.
• Installation: Unlike fiberglass, dense packed cellulose is blown into walls, creating a more snug fit and reducing airflow. However, the installation process requires specialized equipment and professional installation to avoid damaging walls.
• Drawbacks: One significant disadvantage of cellulose is its tendency to settle over time. This settling can create air pockets that reduce its insulating properties, leading to heat loss in the winter and heat gain in the summer. Additionally, if it becomes wet, cellulose takes longer to dry out and can promote mold growth if moisture issues persist.
• Cost-Effectiveness: While cellulose is inexpensive and offers good insulation when first installed, its long-term performance can diminish due to settling, making it less reliable in the long run.

RetroFoam Spray Foam Insulation

When it comes to high-performance insulation, RetroFoam stands out as a premium solution. Unlike fiberglass and cellulose, RetroFoam offers superior thermal performance and other long-term benefits that make it a favorite among Minnesota homeowners.

• Durability: RetroFoam doesn’t settle over time, ensuring consistent performance for the life of your home. This is a major advantage over both fiberglass and cellulose, which can lose effectiveness due to settling or poor installation.
• Energy Efficiency: RetroFoam creates an air-tight seal, preventing drafts and keeping your home’s temperature stable year-round. This means you’ll spend less on heating in the winter and cooling in the summer, making it a cost-effective option in the long run.
• Versatility: Unlike fiberglass and cellulose, RetroFoam can be injected into existing walls without the need to remove drywall. It also works exceptionally well in difficult-to-insulate areas such as concrete block foundations or cathedral ceilings.
• Health and Safety: RetroFoam is non-toxic and has a Class 1 fire rating, providing peace of mind for families. It doesn’t release irritating particles into the air like fiberglass, making it a healthier choice for homeowners with allergies or respiratory conditions.
• Soundproofing: In addition to thermal insulation, RetroFoam offers superior soundproofing, reducing noise from outside and between rooms.

You can add RetroFoam to existing walls relatively easily without removing walls. RetroGreen’s Energy team can improve your energy savings and year-round comfort in less than a day.
