Insulating the floor of 3 season room 6′ above ground
We are planning on adding a 3 season room onto the back of our waterfront house in Virginia. This room will be built 6-10′ above ground as we have a sloped lot towards the water. The question we have is how to insulate as best we can given that we will be using 5 and 6′ wide Larson Scenix windows which we know will at some point be left open during pop up thunderstorms so may occasionally get wet because of this.
We want to insulate as best we can as we will have no HVAC in the room and want to get maximum use. Main question: how to handle the floor, what type of floor etc. We can use PVC planks or PT lumber, but how do we handle the possibility of getting water thru floor which would be a problem with insulation under the floor? Don’t know all the options.
Any thoughts appreciated!
