📊 Interior Wall Sandwich Panel VS Alternative Industrial Partition Materials
2026-08-22
For factory compartment division, warehouse zoning, cold‑storage enclosure and workshop internal partition projects, interior wall sandwich panel, gypsum board, brick‑masonry wall and single‑layer color steel sheet are mainstream interior partition solutions on the market. These materials vary greatly in construction period, fire‑proof performance, thermal insulation, moisture resistance and overall cost. Many buyers tend to make wrong selections, which will lead to subsequent problems such as damp deformation, unqualified fire‑safety standard and prolonged construction cycle. Below is a horizontal comparison of these mainstream partition materials for industrial‑scenario reference.
📋 Material Parameter Comparison Table
| Comparison Item | Interior Wall Sandwich Panel | Gypsum Board | Red‑brick / Lightweight Brick Wall | Single‑layer Color Steel Sheet |
|---|---|---|---|---|
| Construction Speed | ⭐⭐⭐⭐⭐ Modular assembly, short on‑site working period | ⭐⭐⭐ Requires keel installation, multiple working procedures | ⭐ Bricklaying and plastering, long construction cycle | ⭐⭐⭐⭐ Fast installation without thermal‑insulation function |
| Fire‑resistance Performance | Grade A / B optional. Rock‑wool and magnesium‑oxide core reach Grade‑A fire‑proof standard | Ordinary gypsum board is Grade B, strength drops sharply when exposed to water | Grade‑A fire‑proof with stable performance | Only steel sheet itself is non‑combustible, no core‑material fire‑protection capacity |
| Thermal Insulation | ⭐⭐⭐⭐⭐ Excellent insulation performance with PU / rock‑wool / EPS core | ⭐ Hardly any thermal‑insulation capacity | ⭐⭐ Average insulation effect | ⭐ Almost no thermal‑insulation performance |
| Moisture‑proof Performance | ⭐⭐⭐⭐ Suitable for ordinary factories and humid cold‑storage environments; rock‑wool & magnesium‑oxide versions perform better | ⭐ Easy to soften and collapse after damp, not fit for humid workshops | ⭐⭐⭐ Good moisture resistance, prone to dew condensation | ⭐⭐⭐ Steel sheet is water‑proof but non‑insulated, dew‑dripping risk exists |
| Space Occupation | ⭐⭐⭐⭐ Panel thickness 50‑100 mm, small space occupation | ⭐⭐⭐ Medium space occupation | ⭐ Thick wall, large building‑area occupation | ⭐⭐⭐⭐ Small space occupation |
| Reconstruction Flexibility | ⭐⭐⭐⭐⭐ Easy disassembly and reusable | ⭐⭐ Hardly reusable after removal | ⭐ High dismantling cost, non‑reusable | ⭐⭐⭐⭐ Convenient assembly & disassembly, no insulation |
| Typical Application Scenarios | Workshop internal partition, warehouse compartment, cold‑storage inner wall, clean‑room interior wall, fire‑isolation zone | Office partition under dry conditions | Permanent fixed building walls | Simple temporary partition without insulation requirements |
| SAMZOON Remark | Custom‑made interior wall sandwich panel with rock‑wool, PU, EPS, magnesium‑oxide core available. Free samples and material‑selection consultation are supported | Gypsum board not supplied | Brick masonry not supplied | Single‑layer color steel sheet not provided separately; interior wall sandwich panel with core material is highly recommended |
💡 Advantages & Disadvantages Explanation
-
Interior Wall Sandwich Panel It integrates fire‑proof, thermal‑insulation and partition functions. Featuring fast installation and good reusability, interior wall sandwich panel fits ordinary industrial factories, warehouses and cold storages. Specially processed interior wall sandwich panel can also be applied for clean‑room partition. As for drawbacks, interior wall sandwich panel has relatively higher unit cost compared with gypsum board. Proper sealing treatment for panel joints is required to reduce dust accumulation. It is ideal for industrial projects requiring fire‑resistance, thermal insulation and frequent layout adjustment.
-
Gypsum Board Gypsum board owns low cost and fine interior decoration effect. However, gypsum board is water‑sensitive and has no thermal‑insulation property. It cannot be adopted in cold storages, humid production workshops or high‑dust factories. It is only suitable for dry‑environment offices, not recommended for production workshops and warehouses.
-
Red‑brick / Lightweight Brick Wall Brick‑masonry wall features stable structure and reliable fire‑proof & moisture‑proof performance. Nevertheless, brick‑masonry wall takes long time for construction with heavy self‑weight and large space occupation. Dismantling will cost much and cannot be reused. It is fit for permanent fixed walls instead of factories with frequent layout adjustment demands.
-
Single‑layer Color Steel Sheet Single‑layer color steel sheet has fast installation and low cost. Without thermal‑insulation core material, single‑layer color steel sheet suffers dew‑dripping risk under temperature difference, and its fire‑resistance capacity is limited. It is only for simple temporary separation. Do not use single‑layer color steel sheet alone for cold storages or factories with insulation requirements.
