Quick Answer
Blown-in cellulose insulation can reduce energy costs by up to 40% by providing effective thermal resistance in existing walls and ceilings.
How It Works
Cellulose insulation is made from recycled paper products and is blown into walls and ceilings using a specialized machine. It fills gaps and voids, reducing air leaks and providing a solid barrier against heat transfer. The loose-fill fibers can conform to complex spaces, making it an effective solution for retrofitting existing buildings.
Benefits and Specifications
Cellulose insulation typically has an R-value of R-3.5 to R-4.5 per inch, depending on the density of the material. A 6-inch thick installation can achieve an R-value of R-21 to R-27, meeting or exceeding building codes for thermal insulation. When installed correctly, cellulose insulation can reduce energy costs by increasing the efficiency of heating and cooling systems.
Installation and Maintenance
Proper installation is crucial for optimal performance. Cellulose insulation should be blown into walls and ceilings at a density of 3.5 to 4.0 pounds per cubic foot. Regular maintenance is not necessary, but it’s essential to ensure that the insulation is not compressed or disturbed during future renovations or repairs.
