Sandwich panels have become one of the most popular materials in modern construction — from industrial buildings to cold rooms, warehouses, and even mobile units. But despite their many advantages, many buyers fall into common traps that can lead to wasted money, poor performance, or expensive repairs later.

In this article, we’ll uncover 5 common mistakes people make when buying sandwich panels (ساندویچ پانل) — whether it’s a cold storage sandwich panel (ساندویچ پانل سردخانه ای ) a sandwich panel container, or a polyurethane sandwich panel — and give you simple, practical advice to avoid them.

Mistake #1: Choosing the Wrong Type of Panel for the Job

Not all sandwich panels are created equal. Many buyers pick the first panel they see, without understanding its specific use.

• For a cold storage sandwich panel, you need excellent thermal insulation and moisture resistance to maintain low temperatures efficiently.
• For mobile buildings or temporary sites, a sandwich panel container requires lightweight, easy-to-assemble panels with durability.
• If energy efficiency and fire resistance are priorities, a polyurethane sandwich panel is often the best choice.

How to avoid it:
Clearly define the purpose of your project and consult with a supplier about the right type of core material, thickness, and coating for your needs.

Mistake #2: Focusing Only on Price

It’s tempting to go for the cheapest option available, but lower prices often come with hidden costs — such as poor insulation, lower durability, or higher maintenance needs.
For example, choosing a low-quality cold storage sandwich panel can lead to significant energy losses and higher electricity bills over time.

How to avoid it:
Look at the total cost of ownership, not just the upfront price. A higher-quality panel might save you far more in the long run through energy savings and longevity.

Mistake #3: Ignoring Proper Thickness and Core Material

Many buyers assume that all panels have similar performance, regardless of thickness or core material. In reality:

• Thinner panels may not meet insulation or structural requirements.
• EPS cores are cheaper but offer lower thermal performance compared to polyurethane sandwich panels( ساندویچ پانل پلی یورتان ) .

How to avoid it:
Ask your supplier for advice on the optimal thickness and core material for your climate, application, and local building codes.

Mistake #4: Neglecting the Importance of Professional Installation

Even the best sandwich panel won’t perform properly if installed incorrectly. Many buyers try to save money by hiring inexperienced workers or doing it themselves, leading to gaps, leaks, and structural weaknesses.

How to avoid it:
Always hire experienced professionals trained in sandwich panel installation, and ensure proper sealing and alignment for maximum performance.

Mistake #5: Overlooking Supplier Reputation and Support

Many buyers choose unknown suppliers based solely on price and regret it when they face poor customer service, delayed deliveries, or defective products.

How to avoid it:
Work with a trusted, reputable manufacturer who offers guidance, after-sales support, and guarantees on their products — such as Mehdi Panel Company.
