Even walls with good insulation can let warm or cool air escape through cracks and gaps around windows and doors. Drafty homes require more power to heat and cool than tight homes, so save energy by caulking and weather-stripping to stop air leaks. In older homes, it's virtually impossible to seal the house too tightly; in most cases, because of the construction methods used, there will still be enough fresh air to maintain good ventilation after sealing the biggest leaks.
