FRP PLYWOOD FOAM panels are custom manufactured to meet customer service requirements:
• Seamless one-piece construction
• Improved thermal properties
• Excellent impact resistance
• Structural integrity with superior clean ability
FRP PLYWOOD FOAM panels consist of either XPS foam expanded polystyrene foam insulated panels sandwiched between FRP
PLYWOOD A wide variety of options are available to achieve the desired strength, thickness or thermal value enabling you to easily custom specify your foam panel.
1. Choose the desired FRP PLYWOOD (FRP/plywood) thickness and finish for the exterior side of the laminate.
2. Choose the desired type and thickness of the foam core.
3. Choose the FRP PLYWOOD thickness and finish for the interior side of the laminate

Gel Coat. 15 mils (± .003") of a smooth, high gloss gel coat designed to offer superior weathering
characteristics and resistance to UV degradation. All standard Yangzhou Hengyi gel coats are formulated to offer good flexibility,
are acid and alkali resistant and when the surface is properly prepared, will readily accept decals and most paints.
Interior Finishes
Standard - Clear film. A thin clear film is laminated to the interior surface of the panel during the
composite panel production process. This heat sealable film covers typical porosity and provides a surface which is considerably easier
to clean than raw resin surfaces.
Optional - Resin Surface. For applications where sanding, laminating, or bonding to the interior
surface of the panel is required, upon request, Yangzhou Hengy will eliminate the use of the clear film.
A white pigmented polyester resin will be the final interior finish and will contain porosity on the surface.
Optional - Gel Coat. Where additional protection against moisture penetration is desired,
Yangzhou Hengyi will add 15 mils (+-.003") of high gloss gel coat to the interior surface on special orders. Specifications Dimensional Stability minimal shrinkage and/or expansion when exposed to moisture or high temperatures. Size Limitations
Standard panels are available in sizes up to 120" wide x 58' long with a maximum overall thickness of 5". Vertical Stiffeners
FRP Plywood FOAM panels utilize vertical stiffeners 24" on center as standard. Additional stiffeners can be added on special order.
The vertical stiffener consists of ¾" plywood cut to exact thickness of foam running vertically through the panel. Manufacturing Tolerances
Width ± 3mm Length ± 3mm
Straightness ± 3 Squareness ± 3mm
(Adjacent corners) (Diagonal corners) Edge Treatment
An optional edge coating can be applied to each panel prior to shipment to protect panels in transit, or during temporary storage.
