Might also use platic sheeting and or foam board behind to make it air tight.
Thanks, i will keep that in mind. The skirting i used is a thick anti-rip Vinyl. I put a 3/4 sch 40 PVC frame down that is all connected together. The shirting folds under that and then 6" PVC clips snap over the pipe to hold it in place.
The wind would have to move the whole 8'x34' frame to pull the skirting loose. The skirting fastens at the top by metal snaps i installed at 6" spacing.
The skirting fabric has a life time warranty on it.
