RohrDachdurchführungen

RohrDachdurchführungen, or pipe roof penetrations, are essential components in building construction that create a watertight seal where a pipe passes through a roof. Their primary function is to prevent water ingress, which can lead to significant structural damage, mold growth, and compromised insulation. These penetrations are designed to accommodate various types of pipes, including those for ventilation, plumbing, and HVAC systems, and must be compatible with different roofing materials such as shingles, metal, or membranes.

The design of a RohrDachdurchführung typically involves a base flange that conforms to the roof surface and a collar or boot that surrounds the pipe. Materials used for these penetrations vary but often include durable, weather-resistant options like EPDM rubber, metal, or specialized plastics. Proper installation is critical. It requires careful fitting to the roof slope and secure attachment to both the roofing material and the pipe itself. Flashing techniques are often employed in conjunction with the penetration to create an additional layer of protection against water.

Variations in RohrDachdurchführungen exist to address specific needs. Some are designed for single pipes, while others can accommodate multiple pipes. Adjustable or flexible models are available to compensate for thermal expansion and contraction of pipes. Furthermore, specialized designs exist for steep-sloped roofs versus low-sloped or flat roofs, each requiring distinct sealing mechanisms. Regular inspection and maintenance of RohrDachdurchführungen are recommended to ensure their long-term effectiveness and prevent costly repairs.
