Abstract
Unlike traditional gutters that hang from the edge of a building to collect water, internal gutters (also know as build-in gutters and box gutters) are hidden from view, typically behind a parapet or an ornamental cornice, or they form the valley between two sloped roof assemblies. Internal gutters are generally connected to a drain body and an internal downspout, similar to a drainage system for flat roofs.
