Blown insulation, also known as loose-fill insulation, is a type of insulation material that is installed by blowing or spraying it into place.
It consists of small particles or fibers of insulating material, such as cellulose or fiberglass. These materials are blown into the desired space using special equipment, filling cavities and covering surfaces to provide thermal resistance and improve energy efficiency in buildings.
Loosefill cellulose insulation is made of shredded newspapers with non-toxic fire-retardant additives. It has superior thermal, acoustical and fire-resistant properties. It does not promote mold, mildew or fungi growth and it repels insects and rodents.
Loosefill cellulose insulation has the ability to seamlessly cover those difficult spaces like pipes, electrical wiring, and other mechanical areas. Your home needs protection from the elements and with cellulose, you are getting an excellent barrier to airflow, excellent sound insulation, and excellent insulating properties even in the most difficult Canadian climates.
The most common locations for cellulose insulation are attics and walls.
Loosefill Fiberglass insulation is made of finely spun glass fibers. It is primarily composed of recycled glass and sand, making it environmentally friendly and non-combustible.
It resists mold, pests, and moisture, ensuring long-lasting performance. With a high R-value per inch, blown fiberglass helps maintain consistent indoor temperatures, reducing heating and cooling costs while improving your home's overall comfort.
Blown insulation offers many benefits for improving the energy efficiency, comfort, and safety of buildings, making it a popular choice for both residential and commercial applications. Some of these benefits include:
Blown insulation is a loose material that creates a dense, continuous layer that helps to reduce air leaks and makes it an effective air barrier. This minimizes drafts and helps maintain a more stable indoor temperature contributing to the overall energy efficiency.
The versatility of blown insulation makes it a practical choice for a variety of insulation needs, balancing performance, environmental impact, and installation convenience. It can be installed in new constructions or retrofitted into existing buildings without major disruptions.
Blown insulation fills gaps, cracks, and voids effectively, providing a seamless layer of insulation. Due to the consistent thickness across the entire area being insulation, it enhances its effectiveness in maintaining thermal performance, reducing air leaks, and covering irregular spaces.
The blown insulation’s density and fibrous nature make it effective at absorbing sound waves; therefore, creating a quieter indoor environment by effectively absorbing and blocking sound, enhancing both comfort, and privacy within a space. Cellulose provides an NRC of 0.75 @ 1”
Blown insulation materials such as fiberglass are non-combustible and have a high melting point. Cellulose is treated with fire retardants such as Boric Acid during manufacturing. These chemicals are designed to slow down the overall progression of a fire within walls or attics helping to contain the fire and prevent it from spreading rapidly.
Blown cellulose is primarily made from recycled paper products while blown fiberglass is made from a significant percentage of recycled glass. This reuse of materials helps reduce waste and decreases the demand for new raw materials contributing to a lower environmental footprint. The seamless coverage helps improve a building’s energy efficiency by reducing heat loss in winter and heat gain in summer which leads to lower energy consumption for heating and cooling and reduces greenhouse gas emissions associated with energy production.
