A massive compound gothic frame has been custom built with a thermal-barrier aluminum frame with Bovard Studio’s US patented ventilation system designed for the preservation of stained glass windows and installed for Lisbon United Methodist Church in Iowa. The skilled field crew from Bovard Studio carefully operate heavy equipment to lower the frame pieces into the opening. The frame will then receive both interior and exterior heavy wood cladding. Afterward, the restored stained glass panels will be installed one by one.
