Start by drilling holes at the top of each wall cavity. Next, insert the insulation hose into these holes. As you fill the cavity, gradually pull the hose out to ensure even distribution of the insulation material. Maintain a steady pace while filling to prevent blockages. Continue filling each cavity until you encounter resistance, indicating that the space is fully insulated.
The thickness of R49 insulation is typically around 14 inches. This measurement ensures that the insulation provides high thermal resistance, commonly used in attics and other areas requiring significant insulation to enhance energy efficiency and comfort.
Asbestos insulation often appears as thin fibers with a greyish-brown or silver-gold color, and a pebble-like texture.
