ACOUSTIC PRODUCTS
The invention relates to a method of making an insulation product and a novel insulation product, wherein the insulation product is made by adhering a facing to at least one major surface of a batt of man-made vitreous fibres in a matrix comprising a binder by the use of an adhesive and curing the adhesive. The adhesive is an aqueous composition which is free of phenol and formaldehyde and comprises:a component (i) in form of one or more lignosulfonate lignins having a carboxylic acid group content of 0.03 to 2.0 mmol/g, such as 0.03 to 1.4 mmol/g, such as 0.075 to 2.0 mmol/g, such as 0.075 to 1.4 mmol/g, based on the dry weight of the lignosulfonate lignins,a component (ii) in form of one or more cross-linkers.
