King StarBoard®XL

Lightweight Marine Building Sheet

King StarBoard® XL is a lighter, more economical version of the popular King StarBoard®.

This 100% virgin marine-grade polymer has a high density polyethylene cap and a closed cellular inner core which has an excellent surface finish that looks good enough to use in high-visibility applications where structural strength and a finished edge are not important. King StarBoard® XL sheets are up to 30% lighter in weight than King StarBoard,

and are made with the same textured surface and colors for a perfect match. As with King StarBoard®, King StarBoard® XL is made with the exclusive K-Stran™ process for superior consistency and flatness, and has a thickness tolerance of plus or minus 5% (unlike ordinary polymer sheets that use 10% as an acceptable tolerance).
Colors
White/White Light Gray Dolphin Gray Sanshade
Arctic White Seafoam Seapearl Black
