The insulation we have installed over the last 25 years has helped save companies thousands of dollars on energy bills yearly by preventing warn and cold air from escaping their buildings.

Hospitals and clinics

Hospitals are particularly at risk for energy loss because they have many windows and doors, which leave a lot of potential for air leaks. However, OJ Insulation has the experience meeting the sophisticated and often complicated needs of healthcare facilities, and can insulate entire buildings or ductwork with expert care.
