Installing ceiling insulation is an effective way to keep your home cool in summer and to reduce the loss of heat in winter. Insulation reduces the heat transfer between the rooms and the roof area of your home. By blocking this heat transfer with effective insulation, your home can be up to 12 degrees cooler in summer and up to 12degrees warmer during the winter season. And, using less energy on making your home comfortable throughout the year will reduce your energy bills, while you also help lower the amount of green-house gasses emitted into the atmosphere.
