Heating and cooling your home represents almost half of the money you will spend on energy every year. If your home is poorly insulated, those costs can be even greater. The amount of insulation as well as its effectiveness is key to your energy use.
By nature, heat flows from a warmer area to a cooler area due to the difference in temperature. So in winter, the warm air in your heated rooms will move to the cooler, unheated areas such as the attic, garage, crawl spaces, or outside. During summer, the warm outside air will transfer to the cooler interior of your home because of the higher temperature outside as well as the admission of sunlight. In either case, your HVAC system must work to replace or remove the heat lost or gained. The effectiveness of your insulation will directly impact how hard your HVAC system must work which then directly impact your energy costs. (more…)
