Abstract: The present invention provides an encapsulated architectural element that protects its content from atmospheric pressure and temperature, water, humidity and other contaminants. Furthermore, all the components composing the element being encapsulated, thus the element are disposed directly on the floor or other surface and installed in only one step. It is possible to have openings through the encapsulated element, reducing the weight of the element. These openings may be used to refrigerate/heat the floor or other surfaces by the passage of air, gas, fluids or to pass materials or equipment in the openings.
