rookkanalen

Rookkanalen, literally smoke channels, is a Dutch term used to describe ducts within a building that convey smoke and combustion gases from a fire source to the exterior or to a chimney. They can be vertical or horizontal and are commonly found in traditional masonry houses where several fireplaces on different floors connect to a shared flue.

Construction and materials typically include fireproof linings such as brick, ceramic tile, or metal. The diameter and slope are chosen to promote draft and minimize condensation. Features like dampers, inspection doors, and access points for cleaning are common to facilitate maintenance and ensure safe operation.

The primary function of rookkanalen is to remove smoke and byproducts of combustion from living spaces and to deliver them to an exterior outlet or chimney. Proper installation helps prevent backdrafts, reduces smoke intrusion into rooms, and lowers fire hazards. Regular cleaning is essential to remove creosote and soot, which can ignite in certain conditions.

Regulation and maintenance vary by country but generally require correct design, proper connection to an exterior outlet or chimney, and periodic inspection. Clearances from combustibles and appropriate fire-stopping measures are typical requirements, along with documented maintenance to ensure continued safety.

Historically, a single rookkanal in older homes may serve multiple fireplaces across floors. In modern construction, dedicated chimneys or mechanical exhausts often replace or supplement traditional channels. The term remains most common in Dutch architectural discussions and historical texts.
