Fibexpan® is a spray-on product. The spraying technique, also known as flocking, consists in applying Fibrexpan® fibres under pressure using special machines.
The sprayed thickness will be defined according to the desired thermal insulation rating. Fibrexpan ® can be applied in thicknesses of up to 240mm, with no intermediate reinforcement.
The spraying 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.
