Historic Windows

Thermo Expert works with a select group of window manufacturers who can provide historically accurate windows that allow developers to meet the exacting standards of historic preservation organizations and to qualify for Federal and State Historic Tax Credits.

Thermo Expert has completed window installation projects for numerous buildings currently listed on the National Park Service Register of Historic Places – many of which have received historic preservation awards from national, state and local organizations. We work diligently to ensure that our window replacements meet the stringent requirements of the historic Standards for Restoration as defined by the National Park Service.
