Commercial

Windows are a huge source of lost heat, uncomfortable draftiness and noise in commercial buildings.  The combination of glass, which is a poor insulator, and air leakage (infiltration) result in an uncomfortable and noisy winter interior despite large energy bills.  In addition, during the summer those same windows work against the building’s cooling system, allowing hot air to enter the space.  Replacement windows are a costly and disruptive option, often of questionable benefit.  Moreover, in historic preservation situations, replacement windows are not an option at all.  InnerWindows are the most efficient, reliable and cost effective solution.
