Non-wovens are textile structures made from chopped or cut fibre (short) and long fibres (continuous long), bonded together by chemical, mechanical, heat or solvent treatment. The main product groups of the glass fibre non-wovens are needled mats and knitted mats. Non-wovens are often combined with other materials, e.g., laminated. The main benefits of the non-woven glass fibre products are good thermal, sound insulation and high surface areas together with outstanding temperature resistance. The main applications of glass fibre non-wovens are Fire Protection, Transportation, Energy production and storage and Heavy industry, where the main benefits of the glass fibre non-wovens are required.
