In many cases of buildings from the Mid-Modern Era, 1958-1973, insulated glass and thermally broken curtain wall is too heavy to be hung on the existing structure so the “modern” glazing option is not possible. RetroWAL™ places another glass lite behind the existing one, making single glazed windows double and insulated glass windows triple glazed without adding significant weight to the structure. We completely eliminate the high cost, long installation times and will make your older building envelope a very high performer.
