Blown-In Insulation

Definition

Insulation made of cellulose (paper treated with a fire retardant) that is blown into an attic, crawl space, or walls by a blowing machine.

Purpose

Blown-in insulation is used to improve the thermal efficiency of buildings by filling gaps and voids in attics, crawl spaces, and walls. It helps to reduce energy costs, enhance indoor comfort, and provide soundproofing.

Examples of Use

• Installing blown-in insulation in an attic to improve energy efficiency and reduce heating and cooling costs.
• Using blown-in insulation in wall cavities during renovation projects to enhance thermal performance.
• Applying blown-in insulation in crawl spaces to prevent heat loss and improve overall building insulation.

Related Terms

• Cellulose Insulation: Insulation made from recycled paper products treated with fire retardants.
• R-Value: A measure of thermal resistance, indicating the insulating effectiveness of a material.
• Insulation Blowing Machine: Equipment used to blow insulation material into cavities and spaces.

Notes

Blown-in insulation should be installed by professionals to ensure even distribution and adequate coverage. It is important to verify that the material used meets fire safety standards.
