Cellulose insulation offers excellent thermal resistance, helping to minimize heat transfer. It is primarily composed of recycled paper fibers, which create a dense and fibrous structure that effectively slows down the movement of heat. This enhances energy efficiency by reducing heat loss in winter and heat gain in summer. It can be densely packed into wall cavities, attics, and other spaces, creating an effective air barrier which helps to prevent air leakage and infiltration, reducing drafts and improving overall insulation performance. By sealing gaps and cracks, cellulose insulation enhances the building’s ability to maintain a consistent temperature. It also has the ability to absorb and release moisture, helping to regulate humidity levels within the building. It can absorb and buffer excess moisture, preventing condensation and mold growth. This moisture control feature contributes to a healthier indoor environment and protects against potential damage to the structure.
Since Cellulose insulation is treated with fire-retardant additives, such as boric acid or ammonium sulfate, during the manufacturing process, it makes the cellulose inherently fire-resistant, providing an added layer of fire protection to the building. In case of a fire, cellulose insulation can help slow down the spread of flames and reduce damage
