Quizplus · Accepted Answer

Air leakage through walls, windows, and doors typically accounts for the largest percentage of heat loss in a typical house with moderate insulation. This is because air can move more easily through cracks and gaps than through solid materials like walls and ceilings. Therefore, ensuring proper air sealing is an important step in improving the energy efficiency of a home.
