Common Myths About Sandwich Panels Busted

In the construction world, sandwich panels have become a go-to solution for creating durable, energy-efficient, and high-performance buildings. They are used in a wide range of applications, from cold storage and warehouses to industrial sheds and data centers. Despite their growing popularity, many myths and misconceptions still surround sandwich panels, which can prevent people from fully understanding their potential.

In this article, we will bust some of the most common myths about sandwich panels, and shed light on their real capabilities and advantages in modern construction.

❌ Myth #1: Sandwich Panels Are Not Durable

✅ Truth:
One of the biggest misconceptions is that sandwich panels lack durability. In reality, sandwich panels—especially those made with PUF (Polyurethane Foam), PIR (Polyisocyanurate), EPS (Expanded Polystyrene), or Rockwool cores—are designed for strength, long-lasting performance, and resilience.

At leading manufacturers like EPACK Prefab, these panels undergo compressive strength tests and long-term durability checks to ensure they meet international performance standards. With proper maintenance, sandwich panels can last 20-25 years or even longer, making them a viable, long-term building material.

❌ Myth #2: Only Suitable for Temporary Buildings

✅ Truth:
Contrary to popular belief, sandwich panels are not just for temporary structures. They are widely used in permanent buildings such as:

• Cold Storage

• Industrial Sheds

• Warehouses

• Airports

• Data Centers

• Hospitals

The versatility of sandwich panels, combined with their modular design, strength, and superior thermal insulation, makes them a perfect solution for both temporary and permanent construction projects.

❌ Myth #3: They Are Not Fire-Resistant

✅ Truth:
While not all sandwich panels offer the same level of fire resistance, many modern variants, like those manufactured with Rockwool and Glass Wool cores, are fire-rated and meet high safety standards. These materials make sandwich panels suitable for industries where fire safety is paramount.

Depending on the specific application, manufacturers like EPACK Prefab offer panels tailored to meet fire resistance, acoustic needs, and thermal insulation requirements.

❌ Myth #4: Brick Walls Are Always Better Than Sandwich Panels

✅ Truth:
While traditional brick walls have their place, sandwich panels have several advantages:

• Faster construction time, as panels are prefabricated off-site and simply assembled on location.

• Superior insulation, offering better thermal efficiency and reducing energy consumption.

• Lightweight, reducing the load on foundations.

• Better seismic performance due to their lightweight and modular nature.

• Eco-friendly and recyclable.

In terms of cost-effectiveness and sustainability, sandwich panels often outshine brick walls, especially when considering long-term operational savings from energy-efficient buildings.

❌ Myth #5: Panels Don’t Work in Hot & Humid Regions

✅ Truth:
Puf Insulated Cold Room Panels and other sandwich panels are specifically designed to perform well in diverse climates. EPACK Prefab’s panels are made to handle the extreme conditions found in hot and humid regions, including cities like Chennai, Hyderabad, and Kochi.

The PUF and PIR core panels provide low thermal conductivity, ensuring cool interiors even in hot climates. Additionally, the closed-cell insulation prevents moisture ingress, making them ideal for coastal areas or regions with high humidity.

❌ Myth #6: Sandwich Panels Are Too Expensive

✅ Truth:
While sandwich panels may have a higher initial cost compared to traditional building materials like bricks, their lifecycle cost is much lower. Here's why:

• Reduced labor costs due to quicker installation.

• Energy savings thanks to excellent insulation.

• Minimal maintenance requirements over the years.

When you factor in the long-term operational savings, sandwich panels provide a better return on investment (ROI), particularly for large-scale industrial or commercial buildings.

❌ Myth #7: All Sandwich Panel Manufacturers Are the Same

✅ Truth:
The quality of sandwich panels can vary significantly from one manufacturer to another. Key factors that affect performance include:

• Core material (PUF, PIR, EPS, Rockwool)

• Manufacturing process (continuous vs. manual)

• Surface coating and panel bonding techniques

At EPACK Prefab, we use advanced continuous line manufacturing, premium raw materials, and perform multi-stage quality checks to ensure our panels meet the highest standards. Quality control is crucial to ensure that the panels will perform well over the long term, providing the durability and thermal insulation you need for any project.
