STONESIZE FIRE TEST

The external flame spread under fire conditions in buildings is a field that requires maximum attention and study. That is the reason why Tino has developed the Stonesize ventilated facade system with the highest fire safety standards.

The design process of the material is focused on achieving the right balance between the different components: On the one hand, to guarantee the best behavior of the components ensuring the best mechanical performance and lifespan, and, on the other hand, reducing the contribution to fire propagation.

At the same time, the product was developed to substantially slow down the effects of fire on the panel itself, since time is a vital variable in fire scenarios. To that end Stonesize façade panels have all the fire-sensitive layers completely encapsulated, as they are protected by fireproof materials (on the front side by natural stone, on the backside by the aluminum panel and on the edges by mineral mortar).

What is the fire classification of Stonesize façade panels?

The European standard EN 13501-1:2008 sets out the guidelines for the classification of construction materials and systems concerning their level of reaction to fire, based on a nomenclature that establishes values about:

• Flame propagation (classes A1 to F)
• Fall of inflamed particles (classes d0 to d2)
• Smoke emission (classes s1 to s3)

While this standard provides guidelines for obtaining a classification, it has to be based on standardized tests that provide these values. These tests also depend on the classification levels to which the construction system aspires.

To this end, Tino has carried out the following tests (Report No. 083447-1):

• EN 13823:2010+A1:2014, Ventilated facade system SBI (Single Burning Item) reaction to fire test, according to the guidelines established in the EAD 090062-00-0404 KITS FOR EXTERNAL WALL CLADDINGS MECHANICALLY FIXED.
• EN ISO 11925-2:2010/AC:2011, Direct flame flammability test.
