Yalı Stone Wool

Yali Stone Wool is an unfaced stone wool board produced in special size for siding systems. It is utilized for thermal insulation, sound insulation and fire safety.


The boards are placed in between the plastic profiles and wood boards which form the structure of the siding system. If all the components of the system are assembled in a correct manner, no load (lathe, siding profiles, wind, etc.) is imposed on Yali stone wool materials. For that reason, there wouldn’t be any need to connect the boards with anchors. Accordingly, the structural skeleton of the siding is being formed as slightly narrower than the board width so that Stone wool boards can be fastened through squeezing. Since stone wool boards feature 100% dimensional stability no change is observed over the time. For that reason, they continue to serve the purpose of thermal insulation, sound insulation and fire safety during building life cycle. However, if there is any risk that the distance between lathe and/or profiles which form the structure might not remain constant, then they can be fastened with anchor.
