  • Expandable felt (Fibercon)

    Fibercon expandable felt; the perfect solution for expansion gap filling 

    Are you looking for a perfect solution for the filling of expansion joints in areas, which have poor accessibility, such as for instance around burners? The perfect solution is Fibercon Expandable Felt!

    Fibercon Expandable Felt is being manufactured using aluminium oxide (97% Al2O3) fibres with a classification temperature of 1600°C. Because of the fact that the felt expands after being heated, the product is the perfect solution for the filling of expansion joints in, for example industrial furnaces or around burner blocks.

    Fibercon Expandable Felt compensates the expansion and shrinkage. This way the furnace lining life can be extended and installation of the lining can be made easier using Fibercon’s expansion characteristics.
