For this Searay Sundancer we made a rigid enclosure using Tuffak (Markolon) polycarbonate material for the windows. This material does not shrink or stretch in the sun, which keeps it looking as good a new for years.
We used SolarFix thread for these windows. SolarFix is a PTFE (PolyTetraFlouroEthylene) thread because of what it is made out of it has a lifetime guarantee. It is UV resistant and resistant to chemicals too, so this means that this customer will never need any re-stitching repairs. For zippers we used Lenzip plastic molded zippers which also have a lifetime guarantee on them.
