These fabrics designed for internal applications provide various levels of opacity: from 100% blackout to translucent

Using the same weaving technology, Blockout fibreglass yarns can go through various stages :

- Woven and then coated treated after weaving using a chemical and colouring treatment (Blockout fabrics with a translucent appearance:  Paradis 11600).

- Woven, treated and then coated on the reverse side with white acrylic (Obion 11203 dim out fabrics and Flocké 11201 and Kibo 8500 blackout fabrics).

- Thanks to their anti-bacterial treatment, Blockout fabrics are protected from any deterioration and offer greater durability.
