Straight answers
Buying replacement impact windows
How do I know a product is approved for my project?
The accepted quote identifies the exact system and applicable approval documentation. Your contractor or design professional must confirm the size, pressure, anchoring, substrate, and local permit requirements.
Can impact windows be installed into an existing frame?
Some approved replacement systems may allow specific frame conditions, while others require full removal. The substrate, existing frame, water management, and approval instructions must be reviewed on site.
