Frequently Asked Questions about Panel
249.000 – 269.000 VND/m² (updated November 2025)
Yes. Installing panel cladding on a frame is often more cost-effective than building a brick wall, with a difference of approximately 20–40% in total cost. This is because:
Panels come in three main styles: 3-groove panels, 4-groove panels, and 7-wave panels, along with tile-patterned panels. A variety of colors are available, including walnut, white, reddish-brown, and gray.
The surface layer is made of Al-Zn alloy coated steel (55% aluminum + 43% zinc + 2% additives) and coated with Nippon paint, giving the product a variety of attractive colors and long-lasting rust resistance.
Its main function is to provide effective thermal insulation and heat protection for walls and partitions, especially for structures directly exposed to external temperatures such as factories and prefabricated buildings.
Yes. With a high-density PU foam layer of 45kg/m³ and superior thermal insulation properties, the panel is specifically used for wall cladding in projects requiring strict temperature control, such as cold storage and freezer rooms.
PU (Polyurethane) core panels have a higher density of 45 kg/m³ compared to EPS core panels (13-14 kg/m³), therefore they offer better thermal insulation, moisture resistance, fire resistance, and are considered superior.
The difference between plastic panel and alloy panel lies in the material used to construct the outer layer:
Criteria | Plastic Panel | Panel alloy plate |
Shell material | PVC plastic or fiberglass-reinforced composite (FRP) plastic | Color-coated steel (steel, aluminum alloy, etc.) |
Outstanding advantages | Chemical resistant, corrosion resistant, easy-to-clean surface. | Higher load-bearing capacity, good fire resistance, high mechanical strength. |
Application | Cleanrooms, cold storage/food processing plants, seafood processing, chemical plants, coastal construction (corrosive environments) | Industrial workshops, large cold storage facilities, prefabricated buildings, exterior perimeter walls (requiring load-bearing capacity and fire protection). |
If you want to see more details about the structure and price of each type of plastic panel, you can refer to the following article: Plastic panel sheets: Structure, advantages and disadvantages, classification, and price..
The panels are designed with pre-installed tongue and groove joints; simply connect the panels together and screw them into place.This process is simple, requiring fewer surface treatment steps, allowing contractors to complete projects faster compared to traditional methods.
Galawood panels have a fire resistance rating of B1, an important safety standard that helps limit the spread of flames in the event of a fire.
Over 20 years and will not rust for 45 years.

The 2000m² factory was built a month faster than expected. The decision to invest in this foam panel was really the right one, helping me optimize operating costs right from the start.
Since switching to making panels for partitions and temporary houses, the workers have had more free time and the project has been completed twice as fast. Now, I advise homeowners to use them for every project they receive, it's fast and easy and has a quick capital turnover.
Since installing the panels, the house is not only cooler but also less noisy when it rains heavily. Seeing my child sleep better means I know I made the right investment.
