Roof drainage system with internal outflow of rainwater is used in single and multi-bay buildings with multi-plane roofs. Preformed level insulated gutters by Kingspan are perfect for the occasion.

When specifying your insulated gutter, remember that vertical downspouts must not collide with horizontal components of the roof supporting structure (joist girders, truss system, braces, etc.). Internal gutters are not self-supporting and need to be mounted onto a steel subframe.
