Product Specifications

In highly controlled environments like pharmaceutical factories, semiconductor manufacturing, medical laboratories, and aerospace assembly units, maintaining stringent hygiene and air purity is non-negotiable. Handmade cleanroom sandwich panels are purpose-engineered wall and ceiling systems that form the backbone of such sterile zones. Unlike automated counterparts, handmade panels offer greater customization, tighter tolerances, and are often required in complex projects demanding non-standard geometries.

This guide explains the materials, engineering standards, performance metrics, and compliance requirements of handmade cleanroom sandwich panels, equipping project managers, architects, and cleanroom consultants with actionable, regulation-backed insights.

What Are Handmade Cleanroom Sandwich Panels?

Handmade cleanroom sandwich panels are custom-fabricated, multi-layered panels designed for cleanroom construction. Each panel comprises two rigid face sheets and a structural core, assembled manually for precise dimensional control and tailored configurations.

Common Panel Composition:

• Surface Material (Face Sheets):

• Galvanized steel with anti-static PVC coating

• Stainless steel (SUS304 or SUS316L)

• High-pressure laminate (HPL)

• Core Material:

• Rock wool (non-combustible, acoustic performance)

• Aluminum honeycomb (lightweight, high strength)

• PU/PIR foam (thermal insulation)

• Magnesium oxide (MgO) board (fire resistance)

Thickness Range:

• 50 mm to 100 mm typical

• Tolerance: ±0.5 mm

Panel Size:

• Width: up to 1200 mm

• Length: custom (≤ 6000 mm standard)

Engineering Principles and Functional Requirements

Cleanroom sandwich panels must simultaneously fulfill mechanical, thermal, hygienic, and regulatory roles.

Key Industry Standards and Compliance Codes

Handmade cleanroom panels must adhere to a blend of international cleanroom, construction, and fire safety standards.

Advantages of Handmade Cleanroom Panels Over Machine-Made

Use Cases in Critical Environments

1. Pharmaceutical Cleanrooms (GMP-compliant):

• Seamless PU-jointed handmade panels reduce bacterial harbor zones.

• Aluminum honeycomb cores offer superior flatness and anti-static coatings.

• Use of MgO cores for high moisture zones with non-toxic sealing.

• Stainless steel face materials withstand aggressive cleaning agents.

Installation Best Practices

Step-by-Step Assembly Guidance

1. Sub-structure preparation:

• Galvanized or aluminum alloy channel frames

• Tolerance: ≤ 3 mm deviation in vertical and horizontal levels

• Use precision laser levels

• Apply non-toxic sealant (FDA-grade) at joints

• Corners finished with radius aluminum trims

• Silicone or PU-based sealants applied continuously

• Air-leak test (EN ISO 14644-3)

• Surface roughness (Ra < 0.8 μm for critical zones)

Frequently Asked Questions (FAQs)

Q1: Why choose handmade cleanroom panels over standard ones?

Handmade panels allow for custom access hatches, non-linear configurations, and better sealing at critical junctions—making them ideal for highly regulated environments.

Q2: What core material is best for hospital use?

Rock wool is preferred for hospitals due to its fire rating, acoustic insulation, and non-organic composition, preventing mold growth.

Q3: Can handmade panels support suspended fixtures?

Yes. When reinforced with internal steel frames, panels can support loads exceeding 100 kg/m², suitable for air ducts, lights, and sprinklers.

Q4: Are handmade panels GMP and FDA compliant?

Yes, if constructed with non-porous, easily cleanable surfaces, sealed edges, and appropriate non-shedding core materials.
