Historic District Window Replacement Knoxville TN: Materials and Approval

Common Approval Points

While every district has its own process, these are the details that usually matter most:

• frame material and finish
• the sash proportions and how much glass remains visible
• the muntin or grille pattern
• trim, casing, and exterior stop details
• whether the original opening size is preserved
