How to insulate my attic is a question that comes to your mind when you need to cut down your electricity bills. The attic is one of the reasons why you feel cold in winder despite increasing the temperature on the thermostat. Insulation of attics can cool the house in summer and warm in winter. Insulating an attic depends on the space to be covered, the extent of insulation required and the R-value. R-value indicates how much heat flow the insulator will resist. If the R-value is higher, the insulation is better. The attic is the top most part of the house and is more open to the fury to the weather. The attic starts leaking during heavy rains or collects dust and debris on a windy day. Before insulating the attic, you need to consider a few things. Before insulating the attic Remember that you need to make temporary walkways and fix lighting in the attic before you begin insulation process. First, you need to seal any air leaks that you can spot. Air leaks can be near interior partitions, through area around exhaust fan or lights. You also need to keep in mind that if the air leakage through exhaust fans cover is too much, you may need to change it to airtight fixtures. You need to look out and repair any cracks or small openings in the attic, as the air coming inside from these points carries dust. The band around the chimney also needs should be sealed with a sealant that can stand high temperatures. Make sure to close the fissures on the walls and ceilings in the attic before insulation. Ventilation One of the checklists in how to insulate my attic must be proper ventilation. Ventilation reduces moisture content thereby increasing the effectiveness of the insulation. It also prevents ice dams. Ice dams damage the walls and ceilings. Types of insulation Fibreglass rolls or blankets – Made from fibre and glass, Fibreglass insulation are woven together to form a wool like quality. Fibreglass can be rolled out or put across as a blanket and they should be jammed together to provide maximum insulation. Since they come in lengths between 16ft and 100 ft, you should cut them depending on the floor spacing in the attic. There are also fibreglass batts available in the market and are known for their high insulation capacity as the R-value is high. Place the fibreglass batts firmly next to each other and cover the attic area completely. Remember, cutting the fibreglass batts reduces its insulation capacity. Therefore, you do not cut it while insulating your attic. Loose-fill insulation – You can decant or blow the insulation on the attic area. You need a blowing equipment to blow the insulation and that you can rent out from insulation companies. The blower's force pushes the insulation in the desired areas of the attic. You need to blow the loose fill insulation under the floor, after which you cover the attic floor. Hire a contractor Make note that instead of researching more about how to insulate my attic, hiring an insulation contractor is a better option. An insulation contractor is far more experienced in detecting cracks and small openings. He will tell you how much insulation is needed for your attic and how much R-value needs to be achieved. He will also give you tips on keeping your attic dry and leak free. The contractor will do a thorough job in insulating the attic.
