Metal Building

Keeping pace with energy code requirements and how to meet them can be a challenge, but Dow Building Solutions is here to help. Our insulation and air sealing solutions for metal buildings work together to meet both continuous insulation (ci) and air barrier requirements in one easy-to-construct package.

Rigid Foam Insulation Helps Regulate Temperature,
Combat Condensation

As metal easily takes on the outside temperature, metal structures are susceptible to condensation. Such moisture intrusion in metal buildings can lead to a host of problems, including issues with corrosion and mold. A layer of Dow’s rigid foam insulation effectively moderates temperatures and helps prevent condensation. Compared to the fiberglass batt alternative, installing rigid foam insulation in metal buildings eliminates air movement within the insulation, and therefore achieves significantly greater thermal resistance.

Meeting Energy Code Requirements, Enabling a More
Energy-Efficient Building

The codes and design community now recognize the importance of continuous insulation (ci). In fact, in many climate zones, buildings designed under the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) 90.1-2007 and International Energy Code Conservation (IECC) 2009 require ci; it is no longer simply a value-added option.

By adding a continuous blanket of insulation, a significant reduction in heat loss can be economically realized – heat loss that would otherwise have to be accommodated by costly energy-generating technologies. Thermal shorts (heat loss through steel studs) reduce the R-value of cavity-insulated wall systems by more than 50 percent. Installing a layer of high R-value ci over the steel studs reduces the impact of the highly conductive steel and increases the energy efficiency of the structure. For example, a half-inch-thick board of R-3.0 THERMAX™ insulation has the same thermal resistance equivalency to 10 feet of steel – it’s close to 250 times more effective!

Three-Step Process for Meeting Energy Code Requirements

With Dow, meeting today’s energy code standards is as easy as 1, 2, 3.
