Re: High Density Foam being sprayed today...
If you had more room would you consider the spray on foam for the ceiling? We are looking at spray on to do ourselves, and found one where 1" = 6.7 R value and costs about $1.04 per sq foot. Definitely for the walls, but what about the floor? We plan on doing some insulation under the floor, as well as the actual underside of the bus and the ceiling.
