The attic will always be one of the spookiest places in your home. Admit it – it’s cold, dark, and no one will go up there unless you have something to store. However, the attic is also one of the prime places to watch for when it comes to keeping the heat warm in your home. A weakened insulation is one way to seek your energy bills climb up because the heating, ventilation, and air conditioning system has to perform at higher capacity for the same amount of heat.
Installing further insulation requires determining the right R-values for your locality. In the case of Houston, a check of the Energy Department’s national chart shows the city, as well as most of southern Texas, at Zone IV. The category requires the attic to have a thermal protection value at R-49.
Your insulation specialist can determine if the existing insulation is enough for the value and may recommend installing extra. However, placement is key to getting the insulation down pat. Some experts state that if the attic is not used for storage, set up the insulation right on the floor; if the space has trusses linking down to the attic floor the gaps should be sealed with batts or spray-on insulation. However, plan on installing rafter vents to reduce moisture.
