Actually your numbers don't mean squat. Scan and post the build sheets of the windows and the reason Intus is less will be clear.
Can you please be specific in what exactly in the quality of the windows is lacking?
From what I read, they have higher ratings on their leakage and pressure testing than most other windows. They can build a 5x7 window WITHOUT a mullion, while other manufacturers cannot build such a window without a mullion. The reason being is that Intus windows utilizes thicker glass and beefier frames.
