The core difference between “box” gutters and a “European box” gutters is a different design that removes the entire top lip to create a true, square-box profile.
With European box gutters, we’re after a modern, concealed, and seamless look, similar to standard box gutters. The aesthetic advantage of both profiles is that they blend in rather than protrude out from the roofline like common gutter styles.
From a functionality standpoint, European box gutters (similar to standard box gutters) have a larger aperture, meaning the larger style allows them to move water efficiently. This is a tremendous benefit to flat-roof commercial structures, modern homes, and historic homes.
