Revolutionizing Metal Building Insulation Retrofit Applications

RetroShield® is a revolutionary reflective insulation solution for metal building retrofits, uniquely designed for metal and steel building structures. This system redefines retrofit insulation for existing metal buildings, offering a fast, efficient installation process that stands out among other metal building retrofit insulation systems.

Effortless Installation, Exceptional Performance

With our patented Clip & Pin technology, RetroShield® simplifies the retrofit metal building insulation process. This innovation eliminates the need for external supports, making it an ideal metal building insulation retrofit option that promises long-term stability and an aesthetically pleasing finish.

Superior Thermal Performance

RetroShield® retrofit insulation significantly enhances metal building roof and walls, reducing radiant heat transfer by 95%. This reflective insulation technology provides high reflectivity and low emissivity for superior thermal performance. The RetroShield® System offers continuous insulation and can be back-loaded with additional mass insulation for specific thermal performance or R-value requirements.

Condensation will occur on any surface when the temperature of the surface is at or below the “dew-point temperature” for an air-water mixture. The dew-point temperature depends on the dry-bulb temperature (measured with an ordinary thermometer) and the relative humidity in the space next to the surface. The dew-point temperature is less than or equal to the dry-bulb temperature. The two temperatures are equal when the relative humidity is 100%. Some examples of dew-point temperature:


As you can see, condensation can occur when the outside temperature is cold. Insulation below a roof deck will have an inside surface temperature that is above the roof surface temperature. The actual temperature of the inside surface depends on the amount of thermal resistance between the roof and the inside surface. The higher the resistance, the closer the interior surface temperature will be to the inside air temperature. Maintaining a reasonable inside relative humidity (less than 60%) is an important factor in preventing condensation.

Yes. The ASHRAE Handbook values are a subset of data from the National Bureau of Standards (NBS).
