Why We Prefer Cellulose Insulation at Green Minds Building
In the insulation world, there’s a continuous discussion about the best materials for different applications. While various products have their advantages, at Green Minds Building we have a strong preference for cellulose insulation—particularly for retrofits and attic applications.
Here’s why.
The Performance Advantage: R-Value and Density
Cellulose insulation has a higher R-value per inch compared to many common fiberglass options. This means that inch-for-inch, cellulose provides better thermal resistance, helping to keep homes more comfortable and energy efficient.
Another key benefit is that cellulose is dense-packed during installation. When we retrofit walls or attic spaces, we use specialized equipment to pack the cellulose tightly into the cavity. This not only prevents settling over time but also increases its effective R-value by eliminating voids and air pockets.
Fire and Pest Retardant Properties
Cellulose is treated with borates, making it naturally resistant to fire, mold, and pests. This adds a layer of safety and longevity that isn’t always present with other types of insulation. In the event of a fire, cellulose can help slow the spread of flames, providing valuable time for occupants to respond.
The Practical Side: Why We Choose Cellulose
In the industry, there’s a lot of debate about the best attic insulation. It’s often easier and faster for contractors to use fiberglass because it takes up less space in the truck and is quicker to blow. However, we almost always use cellulose because it offers superior long-term performance.
In the long run, the slightly greater effort in handling is more than worth it for the increased comfort, energy savings, and durability.
Conclusion: A Better Long-Term Solution
At Green Minds Building, we believe that the long-term benefits of cellulose—better R-value, superior air sealing, and added safety—make it the ideal choice for many retrofit and attic projects. We don’t just install insulation; we choose materials that deliver real, measurable improvements for our clients.
