Bi-Glass “ When Only the Original Will Do”

Bi-Glass restores and improves the energy efficiency of original wood windows. The Bi-Glass process is actually an alternative to replacing your historic wood windows for both commercial and residential projects.  Over 1,000 historic homes and buildings completed since 1994.

Work can be performed at the job site from our custom mobile work trailers so windows can be back in place at the end of each day. 

  • Original sash and muntins retained- therefore, we don't change the” look” of your windows.  All interior and exterior window trim retained
  • Double-pane low-E glass installed in your sash- provides energy efficiency comparable to a new double pane window.
  • Fully weather stripped-eliminates drafts and paint on paint friction points which is the main source of lead paint dust on operating windows.
  • Improved operation- invisible balance system installed.  Weights removed, pockets insulated.
