A Friendly Reminder About On-Site Measurement and Opening Verification

Custom windows and doors should be based on verified field measurements rather than preliminary dimensions alone. Opening conditions, wall finishes, tolerances, waterproofing details, and related work can affect the final size and installation approach.

What to Consider

An on-site review helps align the product with the actual opening before production. It also provides an opportunity to confirm operation, glass, color, hardware, screens, frame-to-wall details, and the installation schedule.

IGNIS Guidance

Allow time for measuring and confirmation before production. Use the approved drawings, field measurements, and written configuration as the basis for manufacturing and installation.
