Brand: RaxPanel

Panel Sándwich XPS GRP

The GRP XPS Sandwich Panel combines Glass Fiber Reinforced Plastic (GRP) skins with an Extruded Polystyrene (XPS) foam core in a sandwich configuration, delivering thermal insulation and structural integrity for building and cladding applications. GRP skins range from 0.7 to 5.0 millimeters thick, with optional Continuous Fiber Reinforced Thermoplastic (CFRT) sheets for enhanced impact resistance. The closed-cell XPS core, typically 35 to 50 kilograms per cubic meter in density, provides consistent insulation. Embedded aluminum, timber, or fiberglass profiles augment strength, while gel-coat surface treatments in customizable RAL colors add anti-ultraviolet, flame-retardant, and antistatic properties.

The panel’s low thermal conductivity minimizes heat transfer while maintaining lightweight handling characteristics. Its sandwich construction delivers high strength and compression resistance, with waterproof, moisture-proof, and corrosion-resistant performance. Additional features include weather resistance, impact resistance, and anti-mildew properties, ensuring durability across varied climatic conditions.

Applications include wall, floor, and roof panels in recreational vehicles, motorhomes, and caravans. Transportation uses encompass refrigerated truck bodies and trailer panels for temperature control. Marine installations feature interior partitions on yachts and cruise ships, reducing hull weight and improving fuel efficiency. The panel also serves cold storage facilities, mobile homes, and industrial buildings.

Advanced production capabilities enable CNC (Computer Numerical Control) machining for precision cutting and customization up to 12 meters in length and 3.2 meters in width, with thicknesses between 10 and 120 millimeters. Glass Mat reinforced Thermoplastic (GMT) reinforcement layers enhance surface flatness and impact resistance.

GRP XPS Sandwich Panel Selection & Engineering Guide

Las superficies composite de plástico reforzado con fibra de vidrio (GRP / FRP) unidas a núcleos de espuma estructural o colmena proporcionan una superior protección como barrera anticorrosión, alta resistencia a flexión y fácil mantenimiento para recintos marinos y de transporte.

💡 Consejo profesional: Prevención de la delaminación bajo ciclos térmicos
En RaxPanel, utilizamos laminado automático al vacío con adhesivos de poliuretano bicomponente de alto rendimiento para garantizar una resistencia de unión que absorbe la expansión térmica diferencial sin microdelaminación.

1. Cómo elegir el aleación y espesor del revestimiento adecuado

La selección del revestimiento externo determina la resistencia al impacto mecánico, las barreras contra la corrosión y la rigidez estructural en diferentes entornos operativos.

2. ¿Qué tan bien aísla y soporta cargas pesadas el núcleo?

El material del núcleo actúa como el alma de una viga en I, soportando esfuerzos cortantes y manteniendo el aislamiento térmico (valor R):

Métrica de rendimiento	Estándar de ingeniería de RaxPanel	Ventaja de aplicación
Especificación del revestimiento	Hoja de tejido roving de GRP / FRP (0,3 mm – 2,0 mm / 1,0-3,0 mm)	Alta resistencia a la tracción y al impacto contra escombros de la carretera
Thermal Conductivity	~ 0,028 – 0,038 W/m·K	Ahorro de energía con valor térmico R constante
Capa adhesiva	Adhesivo PU / epoxi de dos componentes	Rendimiento libre de delaminación en ciclos térmicos de congelación-descongelación

3. Which Surface Finish Will Protect Your Panels for 20+ Years?

Factory roller coating specifies long-term color stability, UV protection, and resistance against industrial pollutants or marine salt spray.

4. How Fire-Safe and Soundproof Are These Panels?

🛡️ Compliance & Acoustic Isolation:

Fire Safety: Formulations comply with EN 13501-1 Class B-s1,d0 and GB8624 Class B1 building fire safety standards.
Sound Damping: Composite core attenuates noise transmission by 24 dB to 30 dB relative to solid metal sheets.

5. Where Are GRP XPS Sandwich Panels Most Commonly Installed?

🚢 Mamparos de cabinas marinas e interiores de barcos

Salt-spray immune composite bulkheads reducing vessel top-weight.

🚛 Transport Compartments & Chemical Housings

Chemical resistant and high-impact bodywork for aggressive environments.

6. How to Cut, Groove, and Seal Edges During Installation

Panels process easily on-site using standard CNC machinery, routers, or specialized edge profiles for airtight moisture sealing.

Frequently Asked Questions (FAQS)

1. What are the standard panel thicknesses, maximum lengths, and width options available for GRP XPS Sandwich Panels?

Standard panel thicknesses range from 10mm up to 150mm. Standard widths include 1000mm, 1220mm, and 1500mm, with maximum single-sheet lengths up to 5800mm (5.8m) to fit ocean freight container shipping dimensions.

2. What are the primary engineering benefits of using GRP XPS Sandwich Panels?

GRP XPS Sandwich Panels deliver an exceptional stiffness-to-weight ratio, rot-proof moisture resistance, reliable thermal insulation, and dynamic fatigue endurance for high-stress applications.

3. How do these composite panels perform under high humidity and outdoor weathering?

The closed-cell core prevents water logging and condensation absorption, while pre-painted skins provide a 20+ year weatherability barrier against UV degradation.

4. What fire safety ratings and quality certifications do these composite panels meet?

Flame-retardant formulations meet EN 13501-1 Class B-s1,d0 and GB8624 Class B1 fire performance standards. Manufacturing quality is governed under ISO9001 management systems, with raw material performance verified under SGS and CE testing.

5. What surface coating options are available for exterior UV protection?

70% PVDF Fluorocarbon Coating PVDF coating provides a 20+ year exterior weatherability warranty against UV fading and acid rain. FEVE offers high gloss retention, while PE coating is cost-effective for indoor partitions.

6. ¿Estos paneles compuestos pueden ser canalizados, doblados o sellados en los bordes en sitio con CNC?

Sí. Las pieles pre-pintadas se pueden canalizar en V a 90° o 135° en el lado opuesto usando routers CNC estándar o herramientas manuales, permitiendo el doblado manual de bordes en casetes arquitectónicos sin agrietar la pintura superficial.

7. ¿Cómo se empaquetan los grandes envíos de paneles para prevenir daños durante el tránsito marítimo?

Los paneles se empaquetan con película protectora de PE en ambas pieles, separados por capas de espuma intercaladas, y asegurados sobre palets de madera de exportación de alta resistencia o contenedores de acero CKD para prevenir daños durante el flete en contenedores de 20 pies y 40 pies.
