C.P.A. manufactures Isoblok, a system of prefabricated, insulating forms used for casting pools in plaster.

The main feature of the system is its ease of use: After the cement floor is laid, the forms are stacked vertically, and the plaster poured in. The blocks provide double insulation, inside and outside. The system can be used to create any height and shape desired. Besides being cost-effective, it can be installed rapidly, without cluttering the site.

The Isoblok is available in two versions, free-form and rectangular, and each series comes in two different formats.
