A fire-protecting insulation product has air-laid mineral wool fibres and a binder. The binder is the result of curing a binder composition comprising at least one hydrocolloid. The product further comprises a particulate endothermic material.

The invention relates to a mineral wool product comprising mineral fibers bonded by a cured binder wherein the binder in its uncured state comprises at least one protein and at least one enzyme.

A process for manufacturing an acoustical panel comprises mixing an aqueous slurry comprising water and at least about 90 wt. % of mineral wool, glass wool, or a combination of mineral wool and glass wool, the mineral wool, the glass wool, or the combination of mineral wool and glass wool having an average diameter of at least about 5 microns on a dry basis, to produce an acoustical panel having a NRC of about 0.80 to about 1.00 and a CAC of about 30 to about 50.

The invention relates to an aqueous binder composition for mineral fibers comprising at least one hydrocolloid.
