South Carolina Energy Codes

As energy costs continue to escalate from coast to coast, more and more South Carolina metal building owners and contractors are choosing to add insulation to existing metal buildings in a process known as insulation retrofit.

Applying insulation retrofit to an existing steel structure not only results in substantial reductions in energy costs, but also addresses any existing air leaks or condensation issues. Steel Building Insulation, a division of Building Outlet Corp., has assisted consumers with vinyl insulation retrofit projects for more than 30 years, to the extent that more than half of the vinyl fiberglass insulation volume we distribute nationally is now used for metal building retrofit application.

In retrofit application, the metal building's main structural components, either roof purlins or wall girts, are typically 8" deep. We recommend that the entire cavity be filled with insulation to ensure that air space does not exist between the roof and insulation panels, as its existence can cause condensation to form on the inside of the cold surface of the exterior panel.

Our energy efficient insulation materials provide a solution for retrofitting inadequately insulated metal buildings. We can have your insulations rolls cut to the exact length of your required dimensions to save time and money. High r-value insulation systems increase the thermal performance and improve interior environmental conditions for the occupants. Call 1-800-486-8415 to speak with one of our qualified insulation specialists and they can help you select the proper materials for your insulation project needs.
