Sandwich Panels: The Ultimate Guide for Modern Construction

 

Introduction to Sandwich Panels

Sandwich panels have revolutionized modern construction with their lightweight yet strong design. These innovative building materials consist of three layers: two durable outer skins and an insulating core in between. Used in everything from warehouses to hospitals, sandwich panels offer superior insulation, quick installation, and cost savings.

What Are Sandwich Panels? (H2)

Sandwich panels are composite building materials made by bonding:

• Two outer layers (facings): Typically metal, fiberglass, or wood
• One inner core: Insulating material like foam or mineral wool

This unique “sandwich” structure provides:

✅ High strength-to-weight ratio

✅ Excellent thermal insulation

✅ Noise reduction

✅ Fire resistance

How Sandwich Panels Work

The outer layers provide structural strength, while the core offers:

• Thermal insulation (reduces heat transfer)
• Sound absorption (blocks noise)
• Fire protection (in fire-rated cores)

4 Types of Sandwich Panel Cores

1. Polyurethane/PIR Foam

• Best for: Thermal insulation
• R-value: 6-8 per inch (excellent)
• Fire rating: Self-extinguishing
• Used in: Cold storage, clean rooms

2. Expanded Polystyrene (EPS)

• Best for: Budget projects
• R-value: 3.5-4 per inch
• Fire rating: Needs fire retardants
• Used in: Prefab homes, warehouses

3. Mineral Wool (Rockwool)

• Best for: Fireproofing
• R-value: 3-3.3 per inch
• Fire rating: Class A (non-combustible)
• Used in: Industrial plants, hospitals

4. Honeycomb Core

• Best for: High-strength needs
• R-value: Varies
• Fire rating: Depends on the facing
• Used in: Aerospace, luxury buildings
