Reduce Condensation

Easy to Install Insulation and Vapor Retarder; Keeps Your Metal Building Drier, Year-Round.

Why Contractors, Architects, and Builders Choose RetroShield® Reflective Bubble Insulation for Metal Buildings

RetroShield® is a revolutionary system developed for the metal building industry. Attractive, high performing and remarkably easy to install, RetroShield® is ideal for retrofitting and upgrading insulation systems in new and existing metal buildings. Patented Clip & Pin components provide an extraordinary one-pass installation that dramatically reduces downtime for the operation or building owner.

Our patented Clip & Pin components offer a mechanical attachment to the building frame without bands or other support mechanisms required by other systems on the market.

One-Step Installation Process

Installing the RetroShield® System is a simple process that greatly reduces expensive labor costs. The Clip & Pin components easily attach to the lip of the purlin to secure the reflective insulation. Since the system is mechanically attached to the building’s frame without glue or cables, no additional framing or other alterations are needed to complete the retrofit process. This ensures long-term stability and performance and provides an appearance that can be used as the finished ceiling.

Superior Thermal Performance

RetroShield® offers maximum energy efficiency for roof or wall retrofit applications. The system can reduce radiant heat transfer by over 90% when installed. 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: 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).
