Roof drainage is an essential factor in the planning and design of buildings, roofs and facades. Rainwater must be safely drained to prevent flooding or damage to buildings from the outset. In our gutter range you will find different variants.
Function of the internal gutter
The internal gutter is an attractive alternative to the classic curtain-type gutter. Both serve a functional roof drainage, but differ above all in their appearance. The internal gutter has the advantage that it is not visible from the ground and thus does not affect the harmonious overall appearance of a building. Due to its location, it is also protected from wind and weather, and thus has a long service life, although here, too, emphasis should be placed on proper care and maintenance.
OPTIMAL DIMENSIONING OF THE INTERNAL GUTTER
Interior roof drainage systems require exact calculations and precise planning for the optimal dimensioning of the system. Numerous standards and regulations serve as a guide in this regard:
DIN EN 12 0563: Gravity drainage systems inside buildings, Part 3 - Roof drainage, planning and dimensioning
DIN 1986100: Drainage systems for buildings and land, Part 100
