It is used to lead through the slope of the plumb line in sanitary installations and is its ending. It is most often used together with a cover that protects against atmospheric precipitation. Inner diameter 125 mm.

Roof with a vent for sanitary installation - safety and resistance to weather conditions even during hail. They rest firmly on the roof, are extremely resistant to cracking and frost, and moreover, over time, they harden more and more. Braas concrete roofs remain clean for a long time due to the innovative technologies used. They are characterized by an exceptionally good ecological balance.

Concrete roofs are extremely durable, tough and strong. Over time, they cure further and give resistance to harsh weather and extreme weather conditions. Braas concrete roofs are on average 90% stronger than required by NORMA PN-EN 490.

These roofs mute external sounds by about 7 decibels better than ceramic roofs. This reduces the sound pressure by more than half. In this way, concrete roofs give better protection against the increasing noise load from outside.
