Thermolite’s RetroWAL™ interior curtain wall retrofit window system utilizes a window attachment lite that adheres to the interior of an existing window – with no structural reinforcement required.
Three product series are available for RetroWAL™: Silver, Gold, and Platinum, and they are effective at improving energy performance by creating insulating air gaps that can lower U values and increase the performance of the center of the glass. Each specific product series brings a varying level of performance.
