The wall duct WDF for chimney and flue pipes

If you need to put a chimney or flue pipe through a wall, use the fireproof WDF wall duct. This way you will meet all fire protection requirements and prevent any spreading of fires.

A chimney pipe or flue pipe can get very hot during use. At the same time, the number of buildings that have a shell consisting of inflammable building materials is increasing for reasons of heat insulation.

In order to ensure proper fire protection, interior and exterior walls or front insulations consisting made up of inflammable materials like wood or plastic must be protected against excessive heat.

What is a wall duct?

A wall duct is a simple, space-saving, and safe solution ensuring fire protection:

• A wall duct is an easy way of creating a safe distance from the building wall, insulating the flue pipe and thus the heat produced.
• The minimum distance between pipe and wall stipulated by fire-protection regulations can be lowered by a substantial amount.
• Covering the pipe with non-inflammable materials, a time-consuming process, becomes unnecessary.
