50mm thick EPS panel: Structure, advantages and disadvantages, applications, price quote

The 50mm (50cm) thick EPS panel is made up of 3 layers: Two 0,28 - 0,5mm thick surface corrugated iron layers (zinc-aluminum alloy coated steel/aluminum, coated with anti-oxidation electrostatic paint) and an EPS foam core that expands 8 - 20kg/m³, has a low heat transfer coefficient of 0,018 - 0,020 Kcal/m·°C, and can withstand temperatures up to 120°C. Thanks to that, the material is super light, insulating, soundproofing and reduces the load on the construction (1/3 lighter than burnt bricks).

The product has 5 outstanding advantages: Light weight (8 - 20kg/m³), quick construction, low investment cost (saving 40 - 60% compared to traditional materials), effective insulation and environmentally friendly (recyclable, reducing cooling power). However, 50mm EPS panel also has 3 limitations: Low bearing capacity, limited fire resistance and easily affected by humidity if not handled carefully.

The common applications of 5cm EPS panels are concentrated in 4 types of constructions: Hospitals (clinics, operating rooms, thanks to good antibacterial and sound insulation), prefabricated houses (low cost, easy to construct), cold storage - freezer - warehouse (reduce 40 - 50% of cooling electricity costs) and factories - plants (internal partitions, quick renovation).

Regarding price, according to Kosmos survey in September 2025, 50mm EPS panel ranges from 164.000 - 240.000 VND/m², depending on the thickness of the sheet metal (0,28mm price 164.000 VND/m²; 0,50mm price 240.000 VND/m²). Actual cost varies depending on supplier, construction location and order volume.

How is 50mm EPS panel structured?

50mm EPS panel is an advanced construction material, designed with a characteristic three-layer structure, including: Surface corrugated iron layer - EPS foam core - Surface corrugated iron layer.

1. Surface coating: The two layers of corrugated iron on the outside of the 50mm EPS panel have a thickness ranging from 0,28mm to 0,5mm, made from zinc-aluminum alloy coated steel or aluminum. This corrugated iron layer is surface treated with electrostatic painting technology and coated with an anti-oxidation layer, helping to increase the ability to resist corrosion and rust.
2. EPS foam insulation core: The insulation core is made from EPS (Expanded Polystyrene) foam. EPS weighs only about 8 – 20kg/m³ and is processed at high temperatures. This process causes the plastic particles to expand many times their original volume, forming foam blocks containing millions of closed air bubbles, providing superior insulation with a low heat transfer coefficient (about 0,018 – 0,020 Kcal/m/°C).

What are the advantages of 50mm thick EPS panel?

50mm thick EPS panel is a modern material solution, both meeting technical requirements and bringing economic benefits with 5 advantages:

1. Light weight, reducing load on construction: 50mm EPS Panel is produced from expanded polystyrene resin, reaching a uniformity level of nearly 99%. Thanks to that, the product is extremely light in weight, only about 8 - 20kg/m³.
2. Fast construction, saving labor and costs: To construct 100m² of 50mm thick EPS Panel, only about 3 - 5 professional workers are needed.
3. Competitive price: Using EPS panels helps save 40 - 60% of costs compared to traditional materials with the same function.
4. Effective insulation: 50mm EPS panel has a very low heat transfer coefficient, ranging from only 0,018 - 0,020Kcal/m·h·°C. In addition, the EPS core can also withstand temperatures up to 120°C, contributing to improving safety in industrial environments.
5. Environmentally friendly, energy saving: EPS panels are made from safe materials, harmless to health and can be recycled. Thanks to its superior insulation properties, 50mm thick EPS panels can reduce room temperature by 5-8°C compared to the outside environment.

What are the disadvantages of 5cm EPS panel?

When choosing 5cm EPS panel, investors need to pay attention to the following 3 main limitations:

1. Limited bearing capacity: With a thickness of 50mm (the smallest with EPS panel line), the material can hardly achieve the same load-bearing capacity as thicker panel lines (75mm, 100mm). According to construction practice, 50mm panel is only suitable for small projects or areas with little mechanical impact.
2. Fire resistance is not high yet: Although EPS can be supplemented with fire retardants, at a thickness of 5cm, the fire resistance time is only about 30 minutes. Meanwhile, a 100mm thick panel can increase the fire resistance level to nearly 2 hours.
3. Risk of being affected by humidity: EPS has a porous structure and is not very water resistant. If not properly treated and protected, the panel easily absorbs moisture, reducing insulation efficiency and shortening product life.

What projects are 5cm EPS panels mainly used for?

5cm EPS panel with thin, light and stable insulation properties is often used in 3 main categories: Partitions, foundations, and roofs for constructions. Accordingly, 4 types of constructions often use 50mm EPS panel including:

1. Clinic, operating room, clean room, hospital.
2. Prefabricated house, prefabricated house.
3. Cold storage, freezer, cool storage, warehouse.
4. Factories, plants, manufacturing plants.

Clinic, operating room, clean room, hospital

50mm EPS panel is widely used in clinics, operating rooms and hospitals thanks to its heat transfer coefficient of only 0,018 - 0,020 Kcal/m/°C. The EPS foam core ensures a sterile environment, minimizes sound transmission, creates a quiet space, supports the treatment and recovery process. The anti-oxidation galvanized steel surface helps the panel to be antibacterial, anti-mold, and meets the standards of the medical industry.

Prefabricated houses, prefabricated houses

With the advantages of being light, easy to transport and easy to construct, 50mm thick EPS panels are often used in prefabricated houses, temporary houses or worker housing. High durability, heat resistance up to 120°C helps projects maintain quality in harsh weather conditions. Moreover, the low cost of this type of panel helps reduce the investment burden for temporary projects or projects that need to be deployed quickly.

Cold storage, freezer, cool storage, warehouse

5cm panel is the optimal solution for cold storage, freezer, cool storage and warehouse for electronic components, medical equipment, cosmetics thanks to its insulation properties. EPS foam core with closed-cell structure prevents heat loss, reducing up to 40-50% of electricity costs for the cooling system. Anti-corrosion protective layer ensures durability in high humidity environments, commonly found in cold storage.

Factories, plants, manufacturing plants

In production facilities, 50mm EPS panels are often used as internal partitions or to cover auxiliary areas. The advantages of being light and easy to install help the process of renovating or expanding the factory take place quickly, without affecting production activities. In addition, the moderate soundproofing ability of the panel helps reduce noise between work areas.

How much does a 50mm thick EPS panel cost?

According to Kosmos's survey of market prices in September 2025, the current reference price of 50mm thick EPS panel ranges from 164.000 - 240.000 VND/m². Specifically:

Note: Actual costs may vary depending on the supplier, location of the project and the quantity of materials ordered. For large-volume projects or special requirements, unit prices are often flexibly adjusted to optimize costs for the investor.

Frequently asked questions about 50mm thick EPS panel

How to properly preserve 50mm EPS Panel?

To keep the 50mm thick EPS panel in good condition, users need to pay attention to the following 4 things for proper storage:

1. Cover with protective layer when storing: Use thin plastic film or foam to wrap the product to minimize mechanical impact and scratches during transportation.
2. Avoid contact with sharp objects: During both transportation and storage, do not let the panel collide with or place it near objects with sharp edges.
3. Do not place near chemicals or oxidizers.: EPS panels need to be kept in a dry, cool environment, away from reactive chemicals or oxidizing agents.
4. Use specialized lifting equipment: When transporting large quantities, priority should be given to using forklifts or cranes with ropes and specialized support equipment. Absolutely do not use chains because strong impact forces can warp or damage the panel structure.
