How Much Is an Average Attic Insulation Cost and Why Should You Insulate Your Attic?


    Warn air has an affinity towards cooler areas. Therefore, heat is exchanged between the inside air and the air outside in the attic. Warm air leaks outside the house to cooler climate when insulation is not proper, likewise hot air from outside enters the house on warm days. Consequently, your central air conditioning system experiences remarkable stress from this exchange and goes on to consume a whole lot of energy. In such a situation, insulating the attic works for the best as it controls the intense temperature to create a comfortable space. Since the attic is typically the farthest away from the central air conditioning system, it is the hottest region of the house.

    The most commonly used which is also the cheapest insulating material for a home is loose fill fibreglass. Other than that, mineral wool and cellulose can be used as well. Cellulose is eco-friendly and supplies acoustical insulation and high thermal. Batts or roll insulation come in the form of rock wool, cellulose and fibreglass and are slightly costlier than loose fill. Hire a professional if loose fill insulation is what you are going for. For an average-sized attic, the cost would vary somewhere between USD 300 and USD 600.

    However, the cost for attic insulation largely depends on the R-value or the resistance of the particular material. If the R-value of the material is high, it will be all the more effective at insulating. So it is only but natural that the cost of insulation will increase with the increase in the R value. When it comes to attics and other high rise ceilings like those of cathedrals, a greater value of R is preferred.

    On employing a contractor in order to insulate an open attic to contemporary standards, you will likely be spending a sum of USD 0.50 to USD 2.25 per sq ft. It is important to bear in mind that the desired R value and local weather will have a role to play in the cost. In that case, payment amounts to roughly between USD 400 and USD 1800 for a 800 sq ft space. For roll out batting, you will probably incur a cost of USD 100 to USD 500. The size of the attic, the cost of material and the R value will influence the actual cost. Now, blow insulation which places the loose fill substance into the roof or wall or ceiling of the attic demands professional service. The expenses would, thus, be somewhat around USD 2 to USD 3.50 per sq ft. All in all, insulating a 1000 sq ft area will take USD 2000 to USD 3500.
