Keeping warm in the winter and cool in the summer depends on having enough insulation in your home. While insulation can help hold in the heat when it's cold, with proper attic ventilation it can also keep the heat of summer out of your home. The effectiveness of insulation is measured by the amount of heat the insulation can retain during the winter. Weatherization standards for insulation are designed to save you money on your heating bill, while keeping you more comfortable. Prevent heat loss Air leaks in cracks and openings around windows and doors are prime sources of heat loss.
Warm air seeps out through the cracks and is replaced by cold, outdoor air.
Caulking should be used wherever two different materials or parts of a house meet at a stationary location. The most common places are around windows, doors, foundation sills, chimneys, water faucets, vents, electrical outlets and pipes. Landscaping for conservation Planting trees, vines and shrubs in the appropriate places can actually reduce temperature fluctuations in your home. Deciduous trees can help in every season. In the summer, they block the sun with their leafy limbs.
