Insultech offers fabric, metal foil, and sheet metal insulation for on highway engines, which are used in a wide variety of vehicles, including RVs, special purpose vehicles, trailers and semi-trailers, buses, concrete mixers, and both heavy and medium-duty trucks. There are a number of challenges facing on-highway vehicle manufacturers, including meeting emissions targets, protecting against high exhaust temperatures, and surviving corrosive environmental factors such as salt and moisture.  At InsulTech,  we manufacture removable insulation blankets and direct welded heat shields that can help address these challenges.

On-highway vehicles OEMs face stringent pollution control standards that often require the use of selective catalytic reduction systems (SCR). InsulTech heat shields and removable insulation jackets improve SCR performance by maintaining optimal exhaust temperatures.  Additionally, InsulTech’s removable and welded foil heat shield products are designed to survive in corrosive and high moisture environments. InsulTech also offers a wide variety of fabric insulation wraps and jackets to meet the performance, service life and cost requirements of diverse on highway applications.
