When my boat was built thay used just fiberglass insulation around the Ice box and it looses ice quikly. I wont to re insulate and am thinking of using the foam that you spray out of a can. Can any one tell me is that has a very good insulation factor. I know thay make a two part fome that you just pour togetin and it takes off. What do you think
The standard "best" insulation is the extruded styrofoam, also known as Dow "Blue Board". Available in lumber yards in various thicknesses and not real expensive. Its a board-like material and can easily be cut or sawn. Also available in a pink variety. This is not the standard white styrofoam that cups are made of--same material, different process.
The pour in foam was commonly used in the past and has good insulating properties, but it should be sealed against moisture. It also is a tremendous mess. It gets on stuff and is very hard to clean up.
