RetroWAL™: the World's First Do-It-Yourself Commercial Window Retrofit System

Made in the USA, RetroWAL™ is the single most affordable and effective solution for improving energy performance in curtain wall, storefront and window wall buildings. Unlike traditional re¬placement windows, RetroWAL™ installs quickly and easily on the interior of a building’s existing windows, creating an insulating dead air space. The existing glass stays in place, eliminating the need for costly scaffolding or intrusive downtime. Available in both Silver and Gold Series, RetroWAL™ reduces a building’s energy consumption by an average of 20%. The Silver Series uses monolithic low-e glass to convert single pane windows to double pane, while the Gold Series upgrades a single pane window to triple pane with low-e, argon-filled glass. Both the Silver and Gold Series improve building insulation, reduce solar heat gain and air infiltration, and provide effective sound control buildings.

Savings

Everyone wants to cut energy costs, but most energy system upgrades don’t provide an attractive ROI. RetroWAL™ is an interior window retrofit that makes improving your building’s energy performance financially viable.>READ MORE

Efficiency

One of the greatest contributors to energy consumption in curtainwall buildings - especially those with large window-to-wall ratios - is poor insulation. Studies show that glass contributes to 50% of the total building load in cold climates.>READ MORE

Comfort

RetroWAL™ not only significantly improves energy performance, but also increases comfort for tenants and building occupants. Older glass façade buildings often have laboring HVAC systems and leaky windows, which results in hot and cold spots. >READ MORE

Preservation

The National Park Service sets the guidelines for historic buildings. RetroWAL™ easily meets all historic preservation guidelines, which can be one of the biggest challenges when it comes to improving the energy efficiency of historic buildings. >READ MORE

About RetroWAL™

Curtainwall, storefront and window wall systems have been utilized since the 1950s. They consist of non structural tubular aluminum and have non protective glazings. Most all systems built before 1975 have non insulating frames and single pane glass, making buildings perform at less than an R=1 for the exterior. Try building a home today with this insulation value and it wouldn’t be allowed, yet more than 53% of all commercial building windows today perform at this low level. New energy and security requirements necessitate the need for upgrades to these structures, but it has been too expensive to change the glass exteriors of many of these buildings - until now. RetroWAL™ utilizes a “Window Attachment Lite” or WAL®, which is attached to the existing window frame from the interior, thereby creating an insulating airgap and replicating the performance of a new curtainwall. It will triple the energy performance of the window insulation, reduce air infiltration and limit solar heat gain- all for a fraction of the cost of a replacement curtainwall. Buildings
