Comparative Review (Pure Industrial / No Cleanroom)
Industrial Wall Sandwich Panel Core Material Full Comparison ?
| Comparison Item | EPS Wall Sandwich Panel | Rock Wool Wall Sandwich Panel | PU Wall Sandwich Panel | Silicon‑Rock Wall Sandwich Panel |
|---|---|---|---|---|
| Fire Rating ? | Class B2 combustible, basic fire resistance, not for strict industrial fire inspection | Class A non‑combustible, high temperature resistant, excellent fireproof performance for industrial buildings | Class B1 self‑extinguishing, low flame spread, stable for most factory projects | Class A non‑combustible, stable fire performance, no powder falling |
| Thermal Insulation ❄️ | Good thermal performance, suitable for normal temperature industrial space | Average insulation, higher heat resistance but larger thermal conductivity | Top‑tier insulation, thermal conductivity as low as 0.022W/(m·K), best energy saving effect | Balanced insulation performance, stable for all climate zones |
| Waterproof & Damp‑proof ? | Excellent closed‑cell structure, non‑absorbent, anti‑condensation | Poor water resistance, easy to absorb moisture, performance declines in rainy & humid environment | Superior waterproof, fully closed cell prevents sea humidity & rain penetration | Good hydrophobic performance, resistant to outdoor humidity and fog |
| Structural Stability ⚙️ | Ultra light weight, fast installation, easy deformation on large span wall | Medium strength, soft texture, risk of sagging after moisture absorption | High bonding strength, strong wind resistance, not easy to delaminate | High hardness, flat surface, anti‑bulge and anti‑crack |
| Sound Insulation ? | Basic sound insulation for ordinary warehouse | Excellent sound absorption, perfect for noisy production factory | Good sealed sound insulation effect | Balanced noise reduction performance |
| Cost Level ? | Lowest cost, high cost‑performance for temporary construction | Medium‑high price for A‑class fireproof standard | Premium price for high‑end insulation & waterproof | Medium cost, balanced performance & budget |
| Core Strength ✅ | Lightweight, time‑saving installation, budget friendly | Industrial grade fireproof, high temperature resistance, noise reduction | Extreme thermal insulation, waterproof, long service life | A‑class fireproof, weather resistant, neat appearance |
| Main Weakness ❌ | Low fire grade, cannot be used for formal fire‑controlled factory buildings | Easy water absorption, cold bridge risk on panel edges | Higher budget requirement than ordinary panels | Slightly weaker insulation than PU panel |
| Best Application ? | Temporary factory building, simple warehouse, non‑fire standard partition | Chemical factory, high‑temperature workshop, fire‑strict industrial wall | Constant‑temperature factory, energy‑saving exterior wall, cold storage wall | General industrial factory, steel structure exterior wall, workshop partition |
General Market Product Analysis ?
Ordinary EPS wall sandwich panel from mainstream suppliers features low price and fast delivery, but most low‑end products have insufficient core density and unstable fire performance, causing shrinkage and surface bulge after long‑term outdoor exposure.
Common rock wool wall sandwich panel is widely used for industrial fireproof projects, yet most unprocessed rock wool panels have no edge sealing, easily absorbing rainwater and leading to core powdering and performance attenuation in humid seasons.
Conventional PU wall sandwich panel delivers the best insulation performance in the industry, but inferior foaming technology may cause uneven core density and delamination risks. Silicon‑rock wall sandwich panel occupies a balanced market position, while small‑factory products usually have poor flatness and dimension errors.
Scenario‑Based Selection Guide ?
Low‑budget temporary industrial construction: Choose EPS wall sandwich panel. It greatly shortens construction period and satisfies short‑term warehouse and temporary workshop usage with lower investment.
Fire‑critical & high‑temperature industrial zone: Choose rock wool wall sandwich panel. Its Class A non‑combustible property 表现优异 in chemical, mechanical processing and high‑noise factories. SAMZOON PU edge‑sealed rock wool wall sandwich panel effectively solves edge water absorption and cold bridge problems.
Energy‑saving & constant‑temperature factory wall: Choose PU wall sandwich panel. Its ultra‑low thermal conductivity helps reduce equipment energy consumption, and the closed‑cell structure prevents rain and condensation erosion for long‑term outdoor service.
General standard industrial factory exterior wall & partition: Choose silicon‑rock wall sandwich panel. It balances A‑class fireproof, weather resistance and cost, becoming the most versatile option for steel structure industrial projects.
Brand Advantage
As a professional Foshan local source manufacturer, SAMZOON provides full‑series customized industrial wall sandwich panel. We support fast mass production, free sample testing and professional construction technical guidance, fully matching various industrial building enclosure and partition demands.
Purchasing Reminder ⚠️
Never select wall sandwich panel only by unit price. Verify core density, real fire test report, edge sealing process and surface coating weather resistance. For outdoor industrial walls, check wind resistance and waterproof system to avoid long‑term leakage and deformation.
