Why Pick EPS Sandwich Panels for Cold Storage?
Great Insulation and Energy Savings
EPS sandwich panels keep heat out very well. They are perfect for cold storage. Each inch of the panel has an R-value of 5. This means it blocks heat effectively. Unlike other materials, EPS keeps its R-value for years. It doesn’t lose gases because it traps air inside. This air helps the panels work well for decades.
Benefit | Value |
|---|---|
R-value per inch | 5 |
Water resistance | Up to 13 times more than EPS |
R-value retention over 20 years | Minimum of 90% |
These panels save a lot of energy. They can cut energy use by half in cold places. By stopping heat transfer, they keep inside temperatures steady. This protects stored items and lowers costs.
Light and Easy to Install
EPS sandwich panels are light and simple to set up. You can move and install them easily. This saves time and money on labor. Their design allows for quick assembly. They work well for both small and big storage spaces.
Even though they are light, they are strong. The outer layers, often steel or aluminum, make them tough. This mix of lightness and strength keeps your storage safe and sturdy.
Resists Water and Temperature Changes
EPS panels are great at blocking water and handling temperature shifts. Their design stops water from soaking in. This prevents mold and rot in damp places. This is very helpful for cold storage, where dryness is key.
Evidence Type | Description |
|---|---|
Moisture Resistance | EPS panels block water, stopping mold and rot in wet areas. |
Temperature Resistance | EPS panels keep heat out in summer and warmth in winter. |
Energy Efficiency | EPS panels save up to 50% energy in cold areas. |
The panels don’t let much heat pass through. This keeps the inside temperature steady. They also block outside heat, making cold storage work better. This ensures your items stay in good condition.
How Do EPS Sandwich Panels Work in Cold Storage?
Stopping Heat Movement
EPS sandwich panels are made to stop heat from moving. This makes them great for cold storage. Their special design blocks heat from passing through. This keeps the inside temperature steady, no matter the outside weather. Each inch of the panel has a high R-value. This means it resists heat better than other materials. Because of this, cooling systems don’t have to work as hard, saving energy.
Here’s some data to show how these panels work:
Panel Type | Heat Flow (W/m²) | Temperature Difference | Connector Spacing |
|---|---|---|---|
P0 | Highest | Control | |
P2 | 174 | Lower | Staggered |
P3 | 128 | Lower | Staggered |
P4 | 127 | Lower | Staggered |
The table shows that panels with staggered connectors (P2, P3, and P4) have less heat flow than the control panel (P0). This proves EPS panels are good at stopping heat movement.
Keeping Inside Temperatures Steady
EPS sandwich panels are great at keeping inside temperatures stable. Their design blocks outside heat and keeps cold air inside. This helps protect items that need to stay cold. Even in very hot or cold weather, these panels keep the temperature steady. This reduces the strain on cooling systems, making them last longer. It also lowers electricity costs, which is good for the environment.
Feature | Description |
|---|---|
Special design | Blocks heat and keeps cold air inside. |
Controls temperature better than other materials. | |
Energy savings | Uses less power, cutting costs and helping the environment. |
By stopping heat and keeping temperatures steady, EPS panels are perfect for cold storage.

By picking these panels, you help protect the environment. You use less energy and create less pollution. This makes EPS panels a smart and green choice for businesses today.
Reducing Noise
EPS sandwich panels don’t just keep things cold—they block noise too. Their design absorbs sound, making your storage quieter. This is helpful if your storage is near loud places like factories.
The panels stop outside noise, creating a calm space inside. This makes it easier for workers to focus and improves how your storage works overall.
Installation Process of Cold Store Panels
Preparation and Planning
Before setting up cold store panels, plan carefully for success. First, check the storage area. Measure it to know how many panels you need. Clear away any trash or obstacles to make the space ready. A clean area helps avoid delays during setup.
Next, gather all tools and materials. You’ll need items like drills, screws, and sealants. Having everything prepared saves time and keeps things organized. Also, read the manual from the manufacturer. It has important instructions for the panels you’re using.
Tip: Make sure the floor and walls are even. Uneven surfaces can cause problems with panel fitting.
Panel Assembly and Sealing
Putting the panels together is simple if you follow steps. Start by placing the first panel in a corner. Secure it with screws or fasteners. Add more panels one at a time, checking they line up well. Use a level to ensure each panel is straight.
Sealing is very important. Apply sealant along the edges where panels meet. This stops air from leaking and improves insulation. Pay close attention to corners and edges, as gaps often form there. Good sealing keeps the cold store working properly.
Maintenance and Longevity
Taking care of your panels makes them last longer. Check them often for damage like dents or scratches. Clean them gently with mild soap to avoid harm. Don’t use harsh cleaners that might ruin the surface.
Look at the seals regularly. Replace any worn-out sealant to keep insulation strong. Fixing small problems early avoids big repairs later. With good care, your panels can work well for many years.
Note: Keep a record of maintenance checks and fixes. This helps you stay on top of care and repairs.

Comparing EPS Sandwich Panels to Other Materials
EPS Panels vs. Polyurethane Panels
EPS panels and polyurethane panels differ in cost and performance. EPS panels are cheaper, costing $5–$8 per square meter. Polyurethane panels are more expensive, ranging from $10–$15. This makes EPS panels a better choice for saving money.
Polyurethane panels have a higher R-value at first. This means they block heat better per inch. However, both materials lose some R-value over time. Polyurethane panels resist water better, but EPS panels absorb very little moisture and still work well.
Feature | EPS Panels | Polyurethane Panels |
|---|---|---|
R-value | Drops over time due to thermal drift. | Starts higher but also decreases over time. |
Cost | Lower cost. | Higher initial cost. |
Fire Resistance | Tested for one-hour fire rating. | Needs extra fire protection. |
Moisture Resistance | Absorbs little water, stays efficient. | Very low water absorption. |
Mold Growth | Prevents mold growth effectively. | Also prevents mold growth. |
EPS Panels vs. Mineral Wool Panels
EPS panels and mineral wool panels have different uses and costs. EPS panels cost $5–$8 per square meter, making them cheaper. Mineral wool panels cost more, at $8–$12 per square meter. This makes EPS panels better for large cold storage projects.
Mineral wool panels are better at stopping fires and blocking noise. They are good for places needing extra safety or quiet. EPS panels are lighter and easier to install. But in wet areas, they may need replacing sooner, lasting 15–20 years compared to mineral wool’s longer life.
Why Choose EPS Panels?
EPS panels are affordable, easy to use, and versatile. They are light but strong, making them great for cold storage. They keep temperatures steady, saving energy and lowering costs.
While they don’t match mineral wool’s fire safety or polyurethane’s insulation, EPS panels are a good balance. They resist mold and stay efficient even with little water absorption. This makes them a smart and cost-effective choice for businesses.
EPS sandwich panels are great for cold storage use. They keep temperatures steady and lower energy bills. For instance, 8.8 cm thick panels can save $40 per square meter in energy costs in areas with 10,000 cooling degree days. These panels also help the environment by using less energy and cutting emissions. They are strong and last a long time, saving money over the years. Choosing EPS panels improves storage, saves cash, and helps the planet stay green.
