Panel Sándwich Espumoso XPS

XPS Foam Sandwich Panels combine an extruded polystyrene (XPS) foam core with rigid skin layers—typically fiberglass reinforced plastic (FRP), aluminum, or plywood—bonded through vacuum compression molding. The closed-cell XPS core delivers thermal insulation with conductivity between 0.024 and 0.034 watts per meter-kelvin, compressive strength from 0.1 to 1 megapascal, and density of 30 to 50 kilograms per cubic meter. Water absorption remains below 1 percent, while the material performs reliably from -50 to +80 degrees Celsius.

FRP skins provide high strength, rigidity, and corrosion resistance along with waterproof and electrical insulation properties. Aluminum skins offer lightweight, recyclable construction with optional fluorocarbon coatings for enhanced durability. Both skin types bond to the core using high-quality adhesives, ensuring uniform adhesion and structural integrity.

These panels serve construction applications including wall systems, roofing, and partitions where thermal insulation is required. Transportation industries use them for refrigerated truck bodies, recreational vehicles, and marine vessels. Cold storage facilities rely on them for temperature-stable walls and roofs, while industrial settings benefit from their customizable dimensions—widths to 3.2 meters, lengths to 12 meters, and thicknesses from 10 to 120 millimeters—with CNC (Computer Numerical Control) machining available for precise fabrication.

XPS Foam Sandwich Panel Selection & Engineering Guide

XPS Foam Sandwich Panel combines high-strength composite skins with an engineered core to deliver superior thermal insulation, structural rigidity, and long-term durability for commercial applications.

💡 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	Engineered Aluminum / Composite Skin (0.3mm – 2.0mm / 1.0-3.0mm)	Alta resistencia a la tracción y al impacto contra escombros de la carretera
Thermal Conductivity	~ 0.022 – 0.035 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 XPS Foam Sandwich Panels Most Commonly Installed?

🚚 Vehicle Bodies & Trailers

Lightweighting and high-impact structural strength for mobile fleets.

🏢 Cold Rooms & Building Envelopes

Thermal R-value insulation and moisture-proof building enclosures.

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 XPS Foam 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 XPS Foam Sandwich Panels?

XPS Foam 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.
