XPS Sandwich Panels are Available in Different Skin at TOPOLO
Because of the good compatibility between XPS foam and glue system, XPS foam can basically be well combined with existing skin materials without delamination. The commonly used skin materials are FRP sheet, aluminum sheets, plywood, stainless steel sheet, aluzinc sheet, etc.
Fiberglass Skin XPS Foam Sandwich Panels
FRP sheet is a composite containing resin and fiberglass, which has the advantages of high strength, rigidity, lightweight, corrosion resistance, waterproof, and electrical insulation. FRP skin XPS foam core sandwich panels have become the material of choice for many camper and box truck builders. Compared with metal or wood-skinned foam sandwich composite panels, its comprehensive performance advantages are obvious.
What Types of FRP Sheets Does TOPOLO Supply?
TOPOLO supplies FRP sheets for XPS foam sandwich panels in two materials with different resin systems: thermoset FRP sheets and thermoplastic CFRT sheets.

Aluminum Skin XPS Foam Sandwich Panels
The aluminum sheet coating we provide is a high-performance fluorocarbon coating (PTFE, PVDF, FEVE), which can prevent the aluminum sheet from being corroded in harsh weather conditions. The advantage of aluminum sheet is that it is the lightest metal, it will not rust and it is completely recyclable. However, the thinner aluminum plate will be deformed or even cracked after being subjected to a large impact force, which is difficult to repair and affects the appearance very much, so aluminum sheets are usually used as the skin on the inner side. The skin on the other side is made of fiberglass. Usually one side of the aluminum skin is sandwiched with fiberglass or plywood as reinforcement.
Specifications of Aluminum Skin
|Aluminum Grade||1050, 1060, 1100, 1145, 1200, 1230, 1350, 2011, 2014, 2017, 2018, 2124, 3003, 3004, 3105, 4032, 4043, 4145, 5005, 56052, 50603, 508 7049, 8006, 8011, 8079, etc.|
|Surface Coating||PTFE, PVDF, FEVE|
|Surface Color||RAL Color Series|
|Surface Treatment||Brushing, Sandblasting, Polishing, Embossing, etc|
Plywood Skin XPS Foam Sandwich Panels
Because plywood is easy to absorb water and moisture, but it is particularly strong and easy to cut and process, it is especially suitable for indoor furniture materials. Usually the two sides of the xps sandwich panel will not use plywood completely, but use it as one side of the sandwich panel, or laminate it with FRP or aluminum as one side.
Specifications of Plywood Skin
|Material||Beech, Camphor, Willow, Poplar, Eucalyptus, etc.|
|Surface Treatment||Lamination Film|
