Starlite XL is a lightweight marine substrate closed cell utility sheet made from select high-grade King Starboard recycled polymer material. It is ideal for boat parts, as an upholstery substrate and in other behind-the-scenes applications where edges are not visible. Gray in color.
Starlite is approximately 35 percent lighter in weight than classic King StarBoard plastic and offers the same quality textured surface on both sides.

why is it recommended not to expose the edge?
I suspect it is due to appearance. The layers of what looks like plywood is visible along the edges. So the edges do not look like that smooth, slick and polished look of the sides. The stuff is strong, water proof, and works well in the wheel well (back splash) on my boat trailer.
can you use this under foam vinyl seat cushions and staple to it and glue foam to it?
It would work well under foam vinyl seat cushions. Unlike plywood or any other kind of wood, it will never rot. I do not know if it can be stapled or if glue will stick to it.
How much does the 1/2 inch starlite weigh?
It depends on how much you buy? Seriously though, it is comparable to 3/4 inch plywood.
Can I get a piece 12x18?
We only have the sizes listed.
I have a portabote, I wanted to get away from the plywood benches and transom, will any of these materials work for that purpose? thanks, Carl G
hi Edward thanks for the answer. All I would be doing is usung it for benches in the bote and a transom and all these take is a hole drilled in them so I can put a bolt through them with a wing nut does this sound like it would work strenth wise to you? don't think I need any adhesives. Thanks Carl
thanks lee thats what i needed to know. carl
Starboard is structurally similar to plywood, and, of course, is impervious to the elements. It should answer your purpose, as long as the fastenings are mechanical. Adhesives are said not to make a reliable bond with Starboard, so I wouldn't count on mountings via adhesives to hold up or be completely watertight. I've used 5200 with starboard in combo with mechanical fasteners, but can't vouch for the bond.
Thanks Joseph this was the info I was looking for. thanks, carl
The Starboard is a great product where you want something that does not need to be finished or painted and is exposed. However, it doesn't have much structural stiffness, and it is quite a bit heavier than plywood for a given thickness, so I don't think it would be appropriate for a bench seat or transom, unless it is given some reinforcement such as a wooden stiffener brace underneath or in back of a transom.
I purchased the 1/4 inch King Starboard panels to replace the factory plywood floorboard panels. I choose them because it is very durable and will never rot. They are bolted flat to the floor and do not provide any structure nor would I expect this product to provide structure. Since my material is only 1/4 inch thick I wiuld not use it to support weight. I'm not sure if the Starlite would meet the structural requirements of a seat.
King Starboard is indestructable. but also almost impossible to join with any epoxies. I have not found anything that will adhere it except mechanical fasteners. If there is any chance that leaks will be a problem you will need to seal fastener holes well. Also 1/4 is not that strong so you might consider 1/2 inch
I have 3/4 in plywood flooring in my boat now what thickness starboard should I use to replace it?
You could use the 1/2" to replace the plywood. This product is not recommended as flooring as it gets very slippery when wet. Also adhesives do not adhere to this material.
I have made port frames, a gauge panel and access hatches all from King Starboard. This material can be cut or molded like wood and will last forever. If using for benches I would add some non-skid material to keep from sliding around.
