When you are planning to upgrade for modern insulation, Homeowners definitely compare the blown-in insulation and spray foam insulation. Both the insulation offers unique advantages, but by understanding their key differences will help you to choose the best insulation which suits your home.

Blown-In Insulation: Efficient and Affordable
Blown-in insulation is often made from the combination of fiberglass or cellulose. It is applied by blowing the material into the walls, attic or crawl spaces. It is flexible and budget friendly for the older homes which is replaced by adding extra insulation to over existing materials.
Home insulation benefits with blown-in options include:
Quick installation
Effective for hard-to-reach areas
Eco-friendly (especially cellulose made from recycled paper)
Excellent soundproofing qualities
However, it can settle over time, reducing its effectiveness unless topped off.
Spray Foam Insulation: High Performance, Higher Cost
The modern insulation is spray foam insulation which expands to seal the cracks and corners when it is applied. It comes in both the open-cell and closed-cell options with the higher R-values and has strong moisture protection.
Home insulation benefits with spray foam options include:
Superior air sealing
High energy efficiency
Moisture barrier capabilities
Long lifespan without settling
Helps in reducing energy bills over time
While more expensive upfront, it can significantly lower energy bills over time.
Blown-in Insulation vs Spray Foam Insulation: Which Wins?
The right choice depends on your home needs and budget, while comparing the blown-in and spray foam insulation.
Budget-conscious? Go with blown-in for solid performance at a lower cost.
Looking for maximum efficiency and long-term savings? Spray foam is worth the investment.
