Durable Installation
Looking for an insulation solution that lasts? Cellulose is more durable than traditional insulation materials.
Cellulose insulation consists of tiny pieces of paper made up of 85% recycled newspaper. Simply put, small pieces of paper are fiberized so they can be densely packed to prevent slow airflow. Once the material is collected, it’s treated with non-hazardous chemicals, such as borate, for flame retardant properties and resistance to pests and mold. In the end, the R-value for cellulose is 3.8 per inch.
In essence, R-value is a critical metric that gauges the effectiveness of insulation materials in terms of their thermal resistance. By indicating how well a material resists the flow of heat through it, the R-value plays a significant role in maintaining comfortable indoor temperatures and improving energy efficiency. Consequently, a higher R-value means superior insulating properties, which results in reduced heat transfer and, ultimately, lower energy bills. In this regard, the R-value truly matters, as it directly influences the overall performance of insulation, ensuring that homes and buildings maintain an optimal balance between temperature regulation and energy consumption.

Blown in cellulose insulation services are a good investment because the material is energy-efficient. It can effectively fit around obstacles, like recessed light fixtures. Custom-fit insulation provides better performance. In summary, cellulose effectively holds in heat during the winter and keeps heat out during the summer.
Blown in cellulose is perfect for new or existing homes. It’s a great option for retrofit applications because our team doesn’t have to remove your existing walls to apply the insulation. Our team densely packs the insulation to take the guesswork out of the process. Therefore, every inch is protected to provide maximum R-value.

What areas of my home are best for blown in cellulose insulation?
Our local insulation technicians often recommend blown in cellulose for attics because it allows for extra deep coverage. And because cellulose has a higher R-value than traditional fiberglass options, it provides a stronger barrier to limit air leakage. At 5C Energy, Inc., our insulation team has applied blown in cellulose in the walls and attics of thousands of homes in Massachusetts and Rhode Island.
