With rising energy costs, energy efficiency has become essential in new home construction. At Commonwealth Builders, we believe that quality craftsmanship and energy efficiency go hand in hand. Our construction process surpasses industry standards in many areas. For example, in our attics we use insulation with greater thermal resistance (R-45) than the industry standard (R-38). Similarly, TechShield® roof sheathing can be used to reduce the amount of solar heat that radiates into your home. All of this translates to lower heating and air conditioning bills for you.
