Measure the area to be insulated
Choose the correct insulation type and R-value
Wear gloves, long sleeves, eye protection, and a mask
Turn off power to any nearby electrical circuits if needed
Seal air leaks and gaps before installing insulation
Cut insulation to fit the space accurately
Place insulation snugly without compressing it
Keep insulation away from heat sources and recessed lights unless rated safe
Fit insulation around pipes, wires, and obstructions carefully
Avoid leaving gaps, voids, or compressed sections
Secure batts or rolls with staples, supports, or friction fit as needed
Install vapor barriers only where required by local code and climate
Cover exposed insulation if required for safety or code compliance
Inspect the installation for missed spots and uneven coverage
