XPS Sandwich Panels For RV

XPS (extruded polystyrene), which is a rigid foam board made of polystyrene resin, together with other auxiliary materials and polymers, simultaneously heated and injected with a catalyst, and extruded. It has extremely low moisture absorption (almost no water absorption), low thermal conductivity and high compression resistance. It is combined with various reinforcing materials to form a superior performance XPS sandwich panel. Nowadays, XPS composite panels are being used more and more widely in RVs. These composite panels are used for RV siding, flooring, roofing, and even interior furniture.

- Excellent insulation performance
The closed-cell rate of XPS Sandwich Panels for RV reaches over 99%. It forms a vacuum layer between the interior and exterior spaces of the RV, reducing air flow and heat dissipation and ensuring a long-lasting and stable thermal insulation performance of the interior space.

- Excellent high strength and compression resistance
The reinforcement material (GRP/aluminum/wood/plastic) on the surface of XPS sandwich panel greatly improves its impact resistance. The composite panel has a certain degree of toughness. When it is hit by heavy objects, the hard outer material can protect the inner foam material, while the inner foam material can absorb most of the impact, thus greatly improving the safety of the RV.

- Waterproof and moisture-proof
Since there is no gap between the molecules of polystyrene foam, this structure makes the water absorption rate extremely low and basically negligible, which effectively solves the problem of water leakage and moisture in RVs. Water absorption is an important parameter to measure the insulation material. After the insulation material absorbs water, its heat preservation performance decreases. In low temperature conditions, the absorbed water is easy to freeze, which destroys the structure of the insulation material, thus reducing the compressive resistance and insulation performance of the board.

- Light weight
Because the structure of XPS foam board is similar to the honeycomb physical structure, so its density is very low (mostly 35~45kg/m3), and the thickness of the reinforced skin material is limited, so the weight of XPS sandwich panel will not be very heavy. This is very convenient for the cutting, transportation and installation of RV panels.

- Good corrosion resistance
The chemical properties of XPS foam are extremely stable and will not degrade and produce harmful substances in long-term use, and it can still maintain its superior performance under ordinary high temperature environment. This undoubtedly extends the service life of the RV's kitchen and bathing equipment.
