Dec 23, 2009· Re: Floatation calculations, or what will it take to float your boat ? The other thing about the two part pourable foam is that it has to be poured in a warm (80s F) room to get full expansion. In 60s you'll be losing
Considerations When Making a Dock Flotation Calculation. Air Filled vs Foam Filled. An air filled device and a foam filled device have just about the same flotation characteristics sitting dry. Add moisture in the form of condensation or a leak, and everything changes. Water displaces air and if enough gets in it will not support itself. In other words it
"This is the ultimate in closed cell marine flotation foam. The system comes complete with hoses, a gun and spare nozzles. The finished foam weighs only two pounds per cubic foot and is very easy to use. The foam expands to its final size and cures in less than a minute which lets the user see the results almost instantly."

This is the so-called froth flotation. Its variations, acid-froth, agitation- froth, and pneumatic-froth processes are discussed in detail later. Its variations, acid-froth, agitation- froth, and pneumatic-froth processes are discussed in detail later.
Keep in mind, that these are rough calculations. The dock weight, material, decking, and etc. will affect the actual amount of flotation you need. What types of floats do you offer and do they have to be foam filled?
Jul 09, 2010· The max floatation value a cubic foot of foam can give is about 62.8 lbs.. that being the weight of the cubic foot of water that's displaced by the foam. A cube of foam with a low density, say standard 2 lb floatation foam, would provide about 60.8 lbs of buoyancy when fully submerged (62.8 lbs/cf water 2 lbs/cf foam).
