The innovation in the non-woven world proposed by Felbendy

Board type | Sponge Type | Elastic Type | Cushioning Type

 
 
Being structured with non independent bubble cell can represent excellent air permeability.

Also represents the good thermal insulation performance equivalent to the commercially available material.
Viewing air permeability performance with movie.

Air Permeability test  
  Acrylic cup with FELIBENDY board beneath and smoked gas injected to show the air permeability.

A rigid board structured FELIBENDY can present better air permeability than the paper used for sliding door in Japanese interior which is said to have fairly good air permeability.

FELIBENDY Board type can be used for interior or wall to give better air permeability as well as thermal insulation material.
