Stained glass windows were often designed with a minimal amount of framework supporting the stained glass panels. This helped to maximize the amount of area available for art glass and light transmitted through it. If framing turn out to be inadequate to support wind load and leaded glass, problems began to occur. Often stopgap measures were taken to try to remedy the problem such as bracing and protective glazing evident in the window above right.
The examples above illustrate stopgap attempts to strengthen inadequate sash members (window upper right of page).
Full Spectrum Stained Glass decided a better approach could be employed. While the leaded panels were removed for restoration original sash members could be replaced as necessary, repaired and strengthened.
An identical sash was fabricated using high grade plywood. Steel reinforcing was imbedded in the plywood at crucial points in a base of epoxy.
The piggy back sash was cut out and secured with epoxy and mechanical fasteners to the original sash. The result is a new sash with the same sight lines as the original that will support wind load and leaded panels for decades to come with minimal maintenance.
Church representatives review the completed sash prior to reinstallation.
