RetroWAL™ is a groundbreaking solution in the commercial window retrofit industry, designed to enhance the energy performance of curtain wall, storefront, and window wall systems. Established by Thermolite, RetroWAL™ introduces an innovative interior window installation that can significantly improve insulation while preserving the existing glass. This approach allows for rapid installation without the need for costly scaffolding or extensive downtime, creating an insulating dead air space that bolsters energy efficiency.
The system comes in two primary series: the Silver Series and the Gold Series. The Silver Series upgrades existing single-pane windows to double-pane low-e glass, whereas the Gold Series offers an upgrade to triple-pane, argon-filled low-e glass. On average, buildings utilizing RetroWAL™ can expect a reduction in energy consumption by 20%, addressing one of the key factors contributing to high energy expenses in older buildings: poor insulation.
RetroWAL™ not only focuses on energy savings but also enhances tenant comfort by mitigating issues related to air infiltration and solar heat gain. This dual benefit makes it an attractive option for building owners, especially those managing historic properties where traditional window replacements could compromise architectural integrity. Importantly, RetroWAL™ meets National Park Service guidelines, facilitating upgrades while respecting the historical value of buildings.
Targeted primarily at high-rises, office buildings, hotels, and converted apartments, RetroWAL™ provides solutions to complex retrofit challenges frequently encountered by architects, contractors, and energy service companies. The product has garnered popularity among building owners who realize that the affordable and effective retrofit options presented by RetroWAL™ can lead to significant ROI and improved tenant satisfaction. Thus, RetroWAL™ stands as a pioneer in making window retrofitting financially viable, making it a key player in modernizing the building envelopes across urban landscapes.
