Abstract
A fiberglass product usable as an end product or an intermediate product is formed as a pack in a forming station but only 1/7th of the conventional quantity of binder is applied. After curing to a self-sustaining form, additional binder is added at a location remote from the forming station in an amount in excess of the amount required in the final product and then the excess binder and moisture is removed by one or more vacuum stripping steps.
