A precise window spec is one of the quietest ways a builder protects a schedule.
A misordered window on a new build does not just delay one opening.
It can delay framing inspections, siding, and the schedule behind it.
Getting the spec right up front- sizing, glass package, grid pattern, performance rating- is what keeps the rest of the build on schedule.
That is the part of window supply that matters most to a builder, even though it is the least visible part of the finished house. It's also the part we treat as ours, so the builder doesn't have to chase it.
