If you’ve been looking for ways to reduce the energy bills in your New Orleans home, beefing up insulation levels is a great place to start. Adding another layer or two to reach or exceed minimum R-values can have a significant impact on energy usage and comfort. Here are some tips on where to add more home insulation to maximize your investment.
Attic
If you haven’t already done so, consider installing a radiant barrier along the attic floor to reduce heat gain during the summer months. Determine how much and what type of insulation you currently have to see how much to add. Attic insulation is usually in loose-fill or batt form. Aim for an R-value of 30 in the attic, or between 10 to 12 inches, and don’t forget the attic hatch.
Ducts
Seal and insulate ducts in unconditioned spaces. Seal them using foil backed tape. Wrap ducts in blanket insulation and tape them in place.
Exterior Walls
Blow-in home insulation is the least intrusive option in a finished home, and the dense pack technique allows for a considerable degree of air sealing. For a new build, add as much insulation as the wall thickness allows, choosing between batt, spray foam or a wet spray cellulose insulation.
Floors Above Unheated Garages
Begin by sealing any areas where air leakage may occur, such as around electrical or lighting, to help prevent harmful gases from entering your conditioned space. Aim for an R-value of 19 or six inches of cellulose insulation, or opt for spray foam insulation that both seals and insulates.
Cathedral Ceilings
Adequate insulation levels here allow for a more even temperature distribution throughout your home. Batt insulation with a foil-type facing is commonly used, providing the requisite vapor barrier needed in a ceiling without an attic. Maintain the ventilation channel by installing a vent baffle between the roof decking and the insulation.
