Batt insulation consists of pre-cut, flat pieces that resemble small blankets. This type of insulation is one of the most common forms and is available in various materials, including fiberglass, mineral wool, and sheep's wool.
To safely dispose of old insulation, first identify the type of insulation, wear appropriate protective gear, and contact your local recycling centers or waste management authorities for specific disposal or recycling guidelines.
For a basement ceiling, fiberglass batt insulation is commonly recommended due to its effectiveness in preventing heat transfer and its ability to absorb sound. This type of insulation is available in pre-cut panels that fit easily between ceiling joists, making it relatively simple to install.
