What are the key features of Fibrofeu®

Fibrofeu® is a multi-functional product with a range of features: it is rot-proof, non-combustible and easy to work with. Fibrofeu® can be stored for a maximum of 12 months as from the date of manufacture in unopened packaging. Storage conditions: protect from frost, moisture, excessive heat and excessive radiant sunlight.
Fibrofeu® is packaged in 20-kg plastic bags.

The information given in this technical document is based on actual testing and is believed to be product specific. No guarantee of results is however implicit, the conditions of use remaining beyond our control.

With only 45mm thickness, Fibrofeu® provides your concrete slabs with fire resistance for up to 4 hours, as well as acoustic correction with an alpha w = 1

Fibrofeu® areas of application

Fibrofeu® coating is used for passive fire protection and acoustic correction.

Fibrofeu® can be sprayed on concrete floors and structures, concrete beam and slab floors, concrete slabs with structural steel trays, wood floors and steel structures.


Fibrofeu® implementation techniques

Fibrofeu® is sprayed on. The spraying technique, also known as flocking, consists in applying Fibrofeu® fibres under pressure using special machines.
The coating thickness will be defined according to the desired fire insulation rating.

The machine generally comprises a feed hopper, a carding device, a blowing device (fan, turbine or blower), a hose for conveying the mixture to be sprayed. A spray gun and water.

The product is carded in the machine and then conveyed through a hose to a spray gun using compressed air. Water-fed nozzles are placed around the hose outlet to wet the product before it is sprayed onto the substrate.

A bonding agent that is suitable for the substrate must be applied before the coating is sprayed on:

  • Projiso Fixo B® is used for concrete
  • Projiso Fixo M®  is used for metal substrates
  • Projiso Fixo M+® can be used on both difficult substrates.

The applied coating will be finished with Projiso Fixo Dur® or Sidairless®
