Technical Features

The product consists of a semi-rigid non-combustible panel with oriented fibres, treated on both sides with a white ablative coating. With the fibre orientation which is parallel to fire propagation, AF JOINT can be easily compressed crosswise during installation and does not require mechanical support fixings. The industrially applied fireproof coating on both sides provides a ready-to-use product which complies with the test certificates, eliminating the need to paint them on site and verify the thickness consistency of the coatings.
An important product feature is the certified application pattern, i.e. with the product flush with the side of the wall or floor directly exposed to fire. This allows it to be applied at any height of the opening, allowing work from above when there is reduced accessibility from below.
