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.
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.
If your insulation becomes wet, it's crucial to remove and replace it promptly. Wet insulation can significantly lose its effectiveness and may also pose health risks due to potential mold and mildew growth.
