Sandwich Panel Types Comparison | Complete Guide to Choosing the Best Panel Type
Sandwich panels are one of the most important modern materials in industrial, commercial and even residential construction projects. These products consist of two layers of metal sheets and a layer of thermal insulation and are considered a suitable alternative to traditional materials due to their low weight, high strength and quick installation.
In this article, we will introduce the types of sandwich panels and compare them in terms of application, benefits and performance.
Types of sandwich panels and their comparison
1. Metal sandwich panel
This type of panel consists of two layers of metal sheets such as galvanized, aluzinc or aluminum and an insulating core.
Advantages:
• High resistance to fire, corrosion and moisture
• Optimal sound and thermal insulation
• Very high installation speed
• Suitable for walls and ceilings of industrial halls, cold stores and sheds
Application: Industrial, commercial buildings, sheds and production centers
2. Polyurethane (PU) sandwich panel
Polyurethane sandwich panel is one of the best and most advanced panels in the field of building insulation.
Advantages:
• Best thermal insulation performance among panel types
• Low weight and appropriate strength
• High resistance to moisture and corrosion
• Prevent energy loss and reduce heating/cooling costs
Application: Investment buildings, residential buildings, warehouses, production halls and cold stores
3. Polystyrene (EPS) sandwich panel
These panels have a polystyrene core and are mainly used in projects with a more economical budget.
Advantages:
• More affordable than polyurethane
• Good thermal insulation
• Light weight
• Resistant to moisture, corrosion and insects
Application: Industrial projects, warehouses and light structures
Comparison of roof, wall and concrete sandwich panels
1. Roof sandwich panels
These panels are produced with a trapezoidal design to prevent rain and snow from penetrating.
Features:
• Light weight and quick installation
• The best option for the roof of industrial sheds and structures
• Excellent thermal insulation performance
Weaknesses:
• Less resistance to heavy pressures than concrete panels
2. Wall sandwich panels
Used for interior and exterior walls of industrial and commercial structures.
Features:
• Grooved design for interlocking
• Soundproof, heat-insulating and fire-resistant
• Suitable for all types of structures from cold storage to production halls
Weaknesses:
• Not suitable for very heavy structures or severe earthquake-prone areas (compared to concrete panels)
3. Concrete panels
These panels are classified as heavy prefabricated panels and are reinforced with steel.
Features:
• Very high resistance to storms, earthquakes and fire
• Long durability
• Suitable for large and sensitive structures
Weaknesses:
• Very high weight
• Difficult transportation and installation
• Need for specialized equipment
The final comparison of panel types
The best thermal insulation: polyurethane panel
The most economical type: polystyrene panel
The highest structural strength: concrete panel
The best option for the roof: PU or PIR ceiling panel
The best option for the wall: polyurethane panel or grooved metal panel
Summary
To choose the best sandwich panel, you should consider the following:
• Type of structure (industrial, commercial, residential)
• Climate and environmental conditions (heat, cold, rainfall, humidity)
• Project budget
• Need for resistance to fire, sound or vibration
• Speed required to implement the project
Recognizing the strengths and limitations of each type of panel will help you make the best decision for your project and in terms of cost, durability and insulation Achieve the ideal result.
