Panoramica

Informazioni su Stone wool sandwich wall panels

Stone wool cores do not add fuel to a fire; the reaction-to-fire class of the whole panel (for example A2-s1,d0 under EN 13501-1) depends on the facings, adhesive and coating.

Fire resistance (EI) is a property of the tested wall system – panel thickness, core density, joints, fixings and supporting steel – classified under EN 13501-2 from EN 1364-1 tests, or AS 1530.4 / ASTM E119 elsewhere.

Insurer approvals such as FM 4880/4881 or LPS 1181 are panel-specific and are checked when the insurer requires them.

FAQ

Domande frequenti

Does a stone wool core make the wall fire-rated?

Not on its own. A non-combustible core is a material property; a fire-resistance rating comes from a tested wall system with its thickness, joints and fixings.
