Firwin Corp is one of North America's leading manufacturers of removable insulation blankets for On-Highway and Off-Highway vehicles. Our blankets are used for a variety of reasons - protecting personnel from burning themslves on exposed exaust components, lowering ambient heat, and shielding heat sensitive components. More recently, our blankets have become increasing popular becasue of their ability to maintain exhaust temperatures, so that as the exhaust enters the catalyst / SCR, the unit functions properly and pollutant burn-off is accomplished as intended.
