Glass fiber products, including glass fiber mat and insulation products, are described. A glass fiber mat may include glass fibers and a binder. The binder may include cured products from a carbohydrate binder composition. The carbohydrate binder composition may include a carbohydrate, a nitrogen-containing compound, and a thickening agent. The carbohydrate binder composition may have a Brookfield viscosity of 7 to 50 centipoise at 20? C. as measured with a Brookfield viscometer using spindle 18 at 60 rpm. Glass fiber mats may include a component of a roofing shingle. Glass fiber mats may be a facer, battery separator, a filtration media, or a backing mat.
