Claim 0:
1. An insulation product comprising mineral fibers and a binder obtained by curing a binding compound comprising as components:
a) compounds comprising at least one epoxy function, including at least one epoxy precursor chosen from aliphatic compounds comprising at least two epoxy functions, the aliphatic compounds comprising at least two epoxy functions representing at least 50% of the total weight of the compounds comprising at least one epoxy function of the binding compound,
b) a hardener selected from the group consisting of one or more compounds comprising at least two reactive hydroxyl functions,
the one or more compounds being at least one polyol chosen from sucrose, glucose, fructose, lactose, isomalt, isosorbide or talitol, sorbitan, inositol, glycerol, erythritol, arabitol, xylitol, sorbitol, mannitol, iditol, maltitol, isomaltitol, lactitol, cellobitol, palatinitol, maltotritol, starch hydrolysate hydrogenation products or hemicellulose hydrolysate hydrogenation products, trimethylol propane and pentaerythritol, lignin and its derivatives, lignans, ammonium lignosulfate or the alkali or alkaline-earth metal salts of lignosulfonic acid, tannic acids, tannins and condensed tannins,

and
wherein the total weight of binder represents 0.5 to 15% of the total weight of the mineral fibers,
wherein the binding compound comprises 0.5 to 50 parts by weight of epoxy precursor (a) for one part by weight of hardener (b).
