Why Is It Important to Determine the Size of Insulated Panels?
In construction, choosing the correct insulated panel size plays a critical role, directly affecting construction quality, cost efficiency, and project timelines. Each type of project-such as factories, cold storage facilities, cleanrooms, or modular offices-has its own technical requirements. Therefore, accurately determining the panel’s length, width, and thickness is an essential step that should not be overlooked.
Choosing the correct insulated panel size helps optimize thermal insulation, reduce costs, and ensure construction progress stays on schedule.
First and foremost, choosing the appropriate panel size helps optimize thermal insulation and soundproofing performance. Insulated panels with proper thickness and standard proportions minimize gaps, reduce heat loss, and help maintain a cool indoor environment in summer and warmth in winter.
In addition, selecting the correct panel specifications helps reduce material costs, as fewer joints are required, minimizing waste during cutting and installation.
Moreover, standard panel sizes contribute to structural durability and overall aesthetics. Uniform panels with fewer joints create a clean, solid surface that remains strong and visually appealing over time.
For these reasons, determining the insulated panel size from the very beginning is a crucial step in achieving optimal performance for any construction project.
How Many Types of Insulated Panels Are There? Structure of Insulated Panels
Today, insulated panels are manufactured in various types to meet different usage requirements. The four most common types include EPS panels, PU/PIR panels, Rockwool panels, and Glasswool panels. Each type has its own specific characteristics, allowing users to choose the most suitable panel for factories, cold storage facilities, cleanrooms, or residential construction projects.
All insulated panels currently available on the market are produced based on a common structure consisting of three tightly bonded layers: metal sheet – insulation core – metal sheet. This design not only provides structural protection but also maximizes thermal insulation, sound insulation, and fire resistance performance, as detailed below.
The insulated panel structure, consisting of two metal sheets and an insulation core, enhances durability and improves heat resistance.
Surface Metal Sheet Layer
The outer surfaces of insulated panels are typically made of aluminum-zinc alloy coated steel sheets with electrostatic painting, offering excellent resistance to oxidation, corrosion, and enhanced durability for construction projects. In high-standard applications, this metal layer can be replaced with stainless steel.
The metal surface comes in various designs, including flat panels, ribbed profiles for added strength, or color-coated finishes to meet aesthetic requirements.
Insulation Core Layer
This layer is the key component that determines the panel’s primary performance and is made from different insulation materials, including:
- EPS Foam: Lightweight, cost-effective, and provides stable thermal and sound insulation. Fire-retardant black EPS is also available.
- PU Foam: Features a closed-cell structure with high thermal insulation efficiency and lightweight properties.
- Rockwool: Made from light brown mineral fibers, known for excellent fire resistance and superior sound insulation.
- Glasswool: Composed of yellow fiberglass fibers, offering effective thermal insulation and commonly used in cleanroom applications.
Specialized Bonding Adhesive
The two metal sheets and the insulation core are firmly bonded together using specialized adhesive, ensuring strong structural integrity, preventing delamination during use, and extending the panel’s service life.
5 Key Specifications and Dimensions of Insulated Panels
The size of insulated panels is not fixed and varies depending on the product type and specific project requirements. However, there are several important technical specifications that users should clearly understand before installation:
5 Standard Dimensional Specifications of Common Insulated Panel Types Today
1. Panel thickness (cm):
The distance from the top steel sheet to the bottom steel sheet, determining the panel’s sound insulation, thermal insulation, and fire-resistance performance.
2. Steel sheet thickness (mm):
The thickness of each surface steel layer, which can be the same or different on each side depending on project requirements.
3. Panel length (m):
Manufactured according to actual project needs (custom-cut) to minimize joints. Common lengths range from 2.7 m to 5 m, with custom orders available up to 18,000 mm.
4. Panel width (m):
Includes two types:
- Product width: Total width including the joint/locking system.
- Effective width: The actual usable width after installation.
5. Density (kg/m³):
The density of the core material (EPS, PU, PIR, Rockwool, Glasswool, etc.), which directly affects the panel’s weight, durability, and load-bearing capacity.
Each insulated panel type – EPS, PU, PIR, or Rockwool – has its own set of specifications tailored to specific applications such as cold storage, clean rooms, factories, or residential buildings. Understanding panel dimensions and technical specifications helps investors choose the right product, optimize costs, and ensure long-term structural durability.

Some Important Notes When Purchasing Insulated Panels
To select the most suitable insulated panels and ensure effective installation, keep the following key points in mind:
1. Determine the purpose of use
Depending on the type of project-whether it is a factory, cold storage, cleanroom, or residential building-choose the appropriate panel type and size to optimize cost efficiency and functionality.
2. Choose panel thickness based on thermal and sound insulation requirements
For projects that require good thermal and sound insulation, prioritize panels with a thickness of 75-100 mm (7.5-10 cm) to ensure long-term and stable performance.
3. Pay Attention to Steel Sheet Thickness for Outdoor Projects
For outdoor installations that require high load-bearing capacity, thermal resistance, and durability, select panels with a steel sheet thickness of 0.4–0.5 mm to increase stiffness, minimize deformation, and extend the service life of the structure.
4. Consider Panel Density According to Structural Requirements
Avoid using panels with excessively high density for projects that require lightweight construction, such as renovating old houses, ceiling installations, or structures with weak frames, to ensure safety and reduce stress on the supporting structure.
5. Consider Aesthetic Factors
The color and surface design of panels (ribbed or flat) should match the overall architectural design of the project.
6. Choose the Appropriate Panel Thickness for Cold Storage Based on Storage Temperature
For cold storage facilities, panel thickness should be selected according to the intended temperature:
- Frozen storage (-18°C): Use panels with 100-150 mm thickness.
- Chilled storage (0-5°C): Panels with 75-100 mm thickness are suitable.
- Standard storage (10-15°C): Panels with 50-75 mm thickness can be used.
7. Measure Panel Dimensions Carefully Before Ordering
Each project requires different panel dimensions. Accurately measuring the height, width, and installation area will help prevent material shortages or excess, shorten installation time, and optimize costs.
Conclusion:
From the analysis above, it is clear that each type of panel has its own specifications, suitable for different applications ranging from residential buildings, factories, cold storage facilities, to cleanrooms. If you are planning a construction project, carefully consider the panel’s thickness, length, and width to optimize thermal and sound insulation performance as well as its long-term durability.
