The Most Common Mistakes Made When Choosing Sandwich Panels

In this article, we discuss the most common mistakes encountered in sandwich panel selection and how to avoid them.

1. Incorrect Core Material Selection One of the most important factors determining sandwich panel performance is the core (insulation) material. However, in many projects, choices are made purely based on cost without conducting a proper needs analysis.

• PUR panels offer economical solutions but may fall short in projects requiring high performance.

• PIR panels provide high thermal insulation and are suitable for projects focused on energy efficiency.

• Mineral wool (rockwool) panels should be preferred in structures that require fire safety.

A core selection made without considering the project's intended use, temperature requirements, and safety criteria can lead to serious performance losses in the future.

2. Incorrect Panel Thickness Preference Panel thickness is a critical parameter for both thermal insulation and structural performance. Choosing an insufficient thickness leads to high energy consumption, while choosing an excessive thickness unnecessarily increases costs. For example:

• Using low thickness in cold storage facilities causes significant energy loss.

• Choosing a panel that is thicker than necessary in mild climates unnecessarily raises the investment cost.

The correct thickness should be determined by taking U-value calculations and climate conditions into account.

3. Ignoring Fire Resistance and Regulations Fire safety is a critical issue, particularly in industrial and warehouse structures. However, in some projects, panels are selected without paying enough attention to regulatory requirements. Incorrect panel selection:

• Can lead to problems during licensing processes.

• Can affect insurance coverage.

• Can pose a risk to life and property safety.

Therefore, panels with a fire resistance class compliant with the relevant regulations must be preferred.

4. Focusing Only on the Initial Cost Choices made to achieve short-term cost advantages can lead to higher expenses in the long run. Selecting low-quality or incorrect panels:

• Increases energy costs.

• Raises the need for maintenance and repair.

• Shortens the lifespan of the structure.

A total cost of ownership (TCO) approach should be adopted when selecting sandwich panels.

5. Neglecting Installation and Application Details Even the highest quality sandwich panel cannot deliver the expected performance with incorrect application. Joint details, sealing, and installation techniques are of great importance. Incorrect application:

• Can cause water leaks.

• Can create thermal bridges.

• Reduces insulation performance.

For this reason, it is essential to work with expert teams during the application process.

6. Not Considering Climate Conditions When selecting panels, the climate conditions of the region where the structure is located must be taken into consideration.

• High insulation is required in cold regions.

• Resistance to solar radiation is important in hot regions.

• Corrosion resistance comes to the forefront in humid areas.

Selecting panels unsuitable for the climate causes problems in terms of both performance and durability.

7. Ignoring the Manufacturer's Quality In sandwich panel selection, not only the product specifications but also the quality standards of the manufacturer are of great importance. Low-quality manufacturing:

• Shortens the panel's lifespan.

• Causes performance values to fall short in the field.

• Creates additional costs in the long run.
