Thermolite’s RetroWAL adds thermal comfort to single-pane windows.
Thermolite has launched a glazing retrofit system that enables rapid ROI for the commercial energy-efficiency retrofit market. RetroWAL is designed for any curtainwall or storefront and is ideally suited for historic and landmark projects as it allows preservation of the existing façade. RetroWAL consists of a “Window Attachment Lite” or WAL which is easily installed on the inside of the existing glass in as little as 15 minutes and greatly minimizes disruption of building occupants. The product increases the thermal performance of single pane windows in commercial buildings, improving center of glass R-value from R-1 up to R-3 (U-factor 1 to 0.33) with just the basic system. Air infiltration is virtually eliminated and solar heat gain is controlled by the low-e coating, factory applied thermal film orwith between glass blinds.
RetroWAL enhances comfort to tenants by eliminating drafts, glare from the sun and greatly reduces street noise. The technology never needs maintenance and is good for the life of the building.
Priced at less than $20 per square foot and easily installed by a building’s maintenance staff, RetroWAL can potentially deliver the energy performance of a new curtainwall with a five-year ROI all while not displacing tenants nor adding significant weight to the building structure.
