1. What Is an Insulating Paper Honeycomb Sandwich Panel?
An insulating paper honeycomb sandwich panel consists of three main layers:
Outer Facesheets (Skins): Usually kraft paper, aluminum foil, or fiberboard
Core: Honeycomb-shaped kraft paper cells filled with air or insulation material
Adhesive: Environmentally friendly thermosetting glue or PU adhesive
The honeycomb structure mimics the geometry of natural beehives, providing exceptional compressive strength, dimensional stability, and thermal insulation with minimal material use.
2. Structural Design and Engineering Principles
Key Properties:
Sandwich Core Type: Expanded paper honeycomb
Cell Size: 10mm–30mm (hexagonal)
Panel Thickness: 10mm to 100mm
Density: 30–80 kg/m³
Thermal Conductivity (λ): 0.035–0.045 W/m·K
Compressive Strength: 0.5–1.5 MPa depending on core density and facesheet type
🔧 Engineering Principle:
The air-filled cells in the honeycomb structure trap heat and absorb energy, significantly reducing heat transfer and improving sound insulation. The face sheets take on tensile and compressive forces, while the core resists shear deformation—ensuring overall panel rigidity.
3. Thermal and Mechanical Performance Data
| Property | Value | Standard |
|---|---|---|
| Thermal Conductivity (λ) | ≤0.045 W/m·K | ISO 8301 |
| Compressive Strength | ≥0.6 MPa | GB/T 6566 |
| Fire Rating | B2–B1 (depending on adhesive and skins) | DIN 4102 |
| Moisture Resistance | Medium (waxed or laminated surfaces improve performance) | Internal QC |
| Bending Strength | 20–40 N/mm² | EN 310 |
| Sound Absorption | 18–25 dB | ISO 10140 |
4. Manufacturing Process Overview
Step 1: Core Preparation
High-quality kraft paper is slit, printed, and bonded in a zigzag pattern.
The bonded stack is then expanded into a honeycomb core.
Step 2: Adhesion and Lamination
Core is bonded to face sheets (paper, MDF, HDF, aluminum foil) using PU adhesive or hot-melt glue.
A continuous press system ensures uniform bonding and curing.
Step 3: Trimming and Cutting
Panels are cut to size (e.g., 1200mm x 2400mm), optionally CNC-routed for assembly.
Step 4: Quality Inspection
Tests performed for flatness, bonding strength, fire resistance, and dimensional tolerance.
5. Industry Standards and Environmental Compliance
| Standard | Description |
|---|---|
| ISO 16610-21 | Surface profile assessment |
| ISO 8301 | Thermal conductivity of insulating materials |
| DIN 4102 | Fire behavior (B1: hardly flammable) |
| EN 13986 | Wood-based panels for use in construction |
| RoHS / REACH | No heavy metals or harmful substances |
| FSC® Certified Paper | Sustainable forest sourcing |
Most paper honeycomb cores are 100% recyclable, and many manufacturers use formaldehyde-free adhesives.
6. Common Applications and Use Cases
✅ Architectural & Interior Applications
Wall partitions

7. Installation, Handling, and Safety Guidelines
Installation Tips:
Can be mounted with mechanical fasteners, adhesives, or magnetic systems
Ensure surface is dry, clean, and flat
Avoid excessive moisture or direct water contact unless laminated or treated
Handling Notes:
Panels are lightweight yet delicate under point loads—lift using full edge support
Store horizontally in a dry and ventilated area
Safety:
Use dust masks and gloves when cutting
Ensure panels meet fire safety rating for public applications (e.g., B1 DIN 4102)
8. Frequently Asked Questions (FAQs)
Q1: Is paper honeycomb insulation fireproof?
Standard kraft paper cores are not inherently fireproof but can achieve B1 rating with fire-retardant adhesives and surface laminates.
Q2: How strong is a honeycomb panel?
Very strong under distributed loads, but susceptible to point loads or concentrated punctures unless reinforced.
Q3: Can these panels be used outdoors?
Only with UV and moisture-resistant skin layers (e.g., aluminum foil, PVC laminated board). Standard paper faces are for indoor use.
Q4: How does it compare to foam or mineral wool insulation?
Lighter and more eco-friendly than foam
Slightly lower insulation value than mineral wool but better weight/performance ratio
Q5: Are custom sizes and shapes available?
Yes. Panels can be cut, routed, and laminated to fit OEM applications.
