Sustainable and safe: New installation situation for FK90K in clay panel walls

Wildeboer expands the range of applications for its FK90K fire damper – now also suitable for walls with clay panels.

With the newly tested installation situation of the FK90K in walls made of clay panels, Wildeboer is once again setting new standards for sustainable building concepts while meeting the highest requirements for structural fire protection. The innovative combination of proven technology and natural building materials opens up new possibilities for environmentally friendly construction projects.

Compact solution for tight installation situations

The FK90K impresses with its compact design, minimal installation distances and a large free cross-section. This makes it particularly suitable for confined spaces such as false ceilings or raised floors. At the same time, it ensures high volume flows with low pressure losses and a low sound power level – without compromising on safety.

Sustainable building material meets maintenance-free technology

Clay panels are fully recyclable and offer numerous ecological advantages: they regulate the indoor climate, improve room acoustics and contribute to emission-free construction. In combination with the structurally maintenance-free FK90K, the result is a consistent, sustainable solution – ideal for modern timber and solid constructions, listed buildings or energy-efficient renovations.

Easy installation – versatile use

The new installation situation enables secure fastening of the FK90K with mortar, clay plaster mortar or fine clay plaster. The latter even allows precise compensation of installation openings with dimensional deviations of up to 10 mm – a real advantage in practice. The simple processing saves time and material on the construction site.

Advantages of the new installation situation at a glance:

  • Ecological and sustainable: Clay panels are made from natural materials, are 100% recyclable and reusable in terms of a circular economy.
  • Together with the EPD-verified FK90K fire damper from Wildeboer, this creates a consistent, environmentally friendly solution.
  • Improved indoor air quality: Clay regulates humidity, absorbs pollutants and provides pleasant room acoustics with sound insulation of up to 56 dB.
  • Maximum safety: Clay is non-combustible in accordance with DIN EN 13501-1. In combination with the maintenance-free fire dampers, this solution offers maximum fire protection.
  • Easy installation: The optimised installation solution enables time-saving assembly and reduces the amount of material and labour required on the construction site.
  • Wide range of applications: Ideal for interior construction in timber and solid houses, for listed buildings, renovation projects and sustainable construction projects – and perfect for confined installation conditions.
