Our Heat Load Calculator will quickly estimate the amount of heat which will enter your box as well as the total interior volume. This calculator assumes that the inside box volume stays constant and that you are adding the insulation to the outside of the box liner (ie. adding insulation increases the gross space required but does not reduce the inside volume). The heat load given is for daily use of the box by a live-aboard couple in a tropical climate.
Our Box Builder's Calculator will determine the amount of “usable” interior volume in a variety of box shapes based on the total gross space available and the insulation thickness. This calculator assumes that you have a fixed gross volume in which to build a box and reduces the usable interior space as you increase the insulation thickness.
