IRM Foam Filled fenders are manufactured from high quality foam covered by a tough Polyurethane skin. IRM manufactures Foam Filled Fender as an alternative to the standard Pneumatic Fender. The performance of foam filled fenders can be modified by changing the grades of foam. This also gives more flexibility to foam filled fenders in meeting different requirements of berthing energy and reaction force as compared to same size of fenders. Foam filled fenders can also be equipped with a chain and tire net for rough applications.

Since there is no air pressure inside the fender, there is no risk of deflating, bursting or sinking. As there are no end fittings like safety valves, ball valves etc., there is less maintenance required for Foam filled fenders compared to Pneumatic fenders. However, foam filled fender of higher size above 2.2 Meter diameter are generally more expensive when compared to Pneumatic fenders due to the high freight cost.
