The cost of blown in insulations varies based on several key factors. Material selection influences both initial expense and long-term performance, with fiberglass generally being more cost-effective compared to cellulose or mineral wool options. Property size directly correlates with the amount of material and labor required, leading to higher costs for larger spaces. Accessibility issues, such as tight attic spaces or complex rooflines, can increase labor time and expenses. Additionally, the desired insulation thickness impacts material costs, with thicker layers providing better thermal performance but at a higher price point.
