Window air conditioning units can provide added comfort in the hot summer months, but can also create a gap that lets in outside air, dust, insects and pollen. Duck® Brand Air Conditioner Insulating Seals are easy-to-install foam seals that close the gaps between the window A/C unit and window frame. In addition to keeping the cool air in and warm air out, they reduce noise and vibration while blocking unwanted dust, insects and pollen from entering your home. Use together with other Duck® Brand weatherization products to make your home more comfortable and energy efficient all year long.
