The high cost of home insulation primarily stems from the expensive extraction and transportation of raw materials, such as rock or oil. Additional costs accrue during manufacturing, which involves high expenses related to energy consumption and labor, reflecting the overall intensive nature of producing effective insulation materials.
The thickness of R30 insulation is typically 9.5 inches. This measurement helps ensure that the insulation provides the intended thermal resistance, often used in various residential and commercial building applications to enhance energy efficiency.
Cellulose insulation appears fluffy and usually comes in shades of beige, gray, or tan. Its texture and appearance are similar to papier-mâché, paper pulp, or finely shredded paper, giving it a unique and easily recognizable look.
