Questions & Answers

Need styrofoam sheets for a float. Will these float in water?

Need styrofoam sheets for a float. Will these float in water?
Asked by: PM
It will float for sure. It's not tough material so it would have to be protected. I wouldn't try to make a boat out of this but the foam would fill a pontoon float and work great.

I used 31/2 inch special plastic fasteners I bought on Ebay. The insulation is light and easy to cut. Use a long razor to score then break it. Sort of like dry wall. Once I had technique, it was very quick to cut to size. The shiny side radiant barrier looks great and adds alot of light to a dingy space. I will finish by using foam board caulk to seal the top and edges then install white 20 mil vapor barrier to finish the encapsulation. Since the skin on the back side is impermeable, the moisture and condensation problems should drain down the back of the foam and into the drain field I installed. Closing the vents and drying out under the house has made an incredible addition to the comfort of my house. I suggest this product for crawlspace encapsulation.
