Insulfoam R- 3.85 , 1-in x 2-ft x 4-ft Faced Polystyrene Board Insulation

Great product

The item was not available in the store, so the contractors desk got it ordered anddeleivered to my door. Product arrived packaged and in great condition. I used this product to skirt the bottom of my RV, overlayed foam with a vinyl skirt held in place by 2" velcro. Taped all the seams and should be an improvment over the vinyl skirting from last year by it self. Altogether it was very ecomonical way to do to the job. I spent less then $350, when kits ran $ 500 and up.

Good Stuff

I used this styrofoam insulation to fill in on either side of my window air conditioners. The expandable panels that come with the air conditioners don't do much to hold out the heat. I cut it a bit larger than the gap and then stuffed it in place creating an air tight seal. This foam panel seals out the heat and has a laminate coating and after fitting it in place I covered it with left over wall paper. I have plenty left over for any other suitable use that may come along.
