I've had issues on just the covers for the screens, water seems to leech through when we get heavy rain. This may be due to the reflectix I put it there when it's cold, at least that's the best guess I've got. I used
Aqua Armour and had no problems this year, time will tell how long it works for. I applied it both inside and out when I did it. Best would be asking Starcraft, the fabric is
Aqualon 7.
Aqualon has pigmented vinyl resin on the top side. Center a two ply polyester of 9 oz. The underside is coated with a water resistant finish. The 7 stands for the 7 year warranty.
