Spray-On Insulation Cuts Maintenance Costs

One of the common items found on almost every vessel constructed that is frequently overlooked is thermal insulation material. As vessels increase in age.

it is safe to say that the insulation systems start to degrade with time and abuse. In fact, if moisture is ever introduced to the insulation from a leak or poor repair job. it can appear as though none (insulation) was used at all.

In 1995, Mascoat Products, Houston, Texas developed a new spray application thermal barrier system, which has been successfully used on more than 180 vessels worldwide. The system is a water based acrylic binder that encapsulates air filled particles to help reduce or eliminate most radiant heat/cold transmission.

Sprayed on the inside shell of most modern vessels at one millimeter (0.020-in.), Delta T Marine bonds directly to the substrate leaving no room for development of corrosion under insulation. Most vessels are now insulated and protected from corrosion and thermal transfer of roughly an R9-13 factor as compared with conventional insulation.
