Abstract
A method of manufacturing a cover for a spa includes the steps of vacuum molding a first shell member and a second shell member, bringing the first and second shell members into registration with one another to define a hollow cavity therebetween, and injecting a foam into the hollow cavity, wherein the foam is configured to bond with the shell members to create a unitary structural part that provides increased strength and rigidity.
