Tile with ventilation chimney, internal diameter 150 mm.

To connect the ventilation ducts with the fireplace, a flexible duct is used to match the diameter of the fireplace. The Duro Vent fireplace can be placed vertically with a roof pitch from 15 to 55.

Concrete roofs are safe and resistant 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.
