I have 1/2" thick x 48"W x 85 3/4"L sheets for sale. Actual net thickness is 15/32"( that is 1/32" shy of 1/2", just like plywood).
These sheets are Structural Fiberglass Composite Panels, that have a NidaCore / PlasCore PP Honeycomb Core.
They are as strong as 1/2" plywood, yet are 50% of the weight...These sheets weigh 24# lbs. each.
They are Prefinished on one side (A), with 15 mil. thick high gloss Exterior Grade Gel Coat...With a colored resin on the back side (B).
They have some thermo insulation properies at R-2.75 value, as well as some sound deadening insulation as well.
These panels are used for modern day composite Boat Builds, as well as very high end Off-Road Trailers & Campers.
I'm a partially retired boat builder, and I'm selling off my private stock...I have quite a few panels and can likely supply a medium size professional boat builder.
I'm offering these for sale, at about 1/3 the price you can find anywhere...Might be worth your travel time.
Note: I have other sizes of panels as well, so should you need honeycomb core fiberglass panels, please don't hesitate to ask. Prices vary due to thickness, and size. The size I have advertised here, is the least expensive per square foot of any stock I have.
If you want to build something that will last a lifetime, with the least amount of maintenance, this is a great choice!
Price is firm at $110.00 per sheet (that's only $3.85 per sq. ft.) Cash only!
