Profile Great Wall Board Wholesale in Practice: From Material Selection to Installation for a Summer Insulation Exterior Wall

This summer, the owner of a commercial complex in Foshan approached us to renovate the exterior wall. The original wall was made of ordinary single-layer aluminum panels, causing indoor temperatures to remain high in summer and energy consumption for air conditioning to be excessive. We needed a decorative material that was both aesthetically pleasing and insulating. After multiple comparisons, the owner ultimately selected Profile Great Wall Board and required a thermal break structure. As a project of 佛山市壹元建材科技有限公司, this article shares the complete material selection and construction process.

Project Background: Insulation Urgency, Tight Schedule

The project is located in Nanhai District, Foshan, a 6-story commercial building with an exterior wall area of approximately 2,000 sqm. The owner reported severe afternoon sun exposure, with indoor temperatures 3–4°C higher than surrounding buildings. After on-site inspection, we recommended installing Profile Great Wall Board with an insulation layer, utilizing its cavity structure to form an air insulation layer, combined with thermal break profiles to reduce heat transfer. The owner accepted the plan and required delivery and installation within 15 days.

Material Selection: Cost-Effectiveness of Factory-Direct Profile Great Wall Board

We recommended a Profile Great Wall Board manufacturer—a local Foshan company specializing in engineering aluminum, which is our company, 佛山市壹元建材科技有限公司. Why choose a local manufacturer? First, fast supply—local warehouse in Foshan has ample stock and complete models. Second, on-site sample selection ensures color and surface treatment meet design requirements. Finally, we selected 1.5mm thick fluorocarbon sprayed great wall board in light gray with thermal break strips. A key point: the Profile Great Wall Board quotation should include profiles, thermal break strips, spraying, packaging, and transportation. We provided a comprehensive per-square-meter quotation excluding installation, and the owner arranged their own installation team. We provided technical guidance.

Construction Key Points: Coordination of Keel and Insulation Layer

During construction, we first installed hot-dip galvanized steel keels on the wall, sandwiching 30mm thick rock wool insulation between the keel and the wall. Then we installed the dedicated hanging parts for the great wall board using a clip-on method, requiring no adhesive. Note: since the Profile Great Wall Board can be up to 6 meters in length, handling and installation require multiple workers to avoid deformation. In high summer temperatures, the sprayed surface is prone to dust contamination, so it must be cleaned before installation. Also, check the sealing of the thermal break rubber strips to prevent thermal bridging. We sent a technician on-site for two days to guide workers in adjusting hanging part spacing and leveling.

Results: Insulation Measurement and Appearance

After installation, the owner used an infrared thermometer to measure: under the same sunlight conditions, the exterior wall surface temperature dropped from the original 50°C to about 38°C, and the indoor air conditioning load decreased significantly. In appearance, the distinctive vertical lines of the great wall board gave the building a layered look, and the light gray fluorocarbon paint showed strong weather resistance, harmonizing with the surrounding environment. The owner was very satisfied and immediately stated that the same material would be used for the second phase of the project.

Procurement Summary: Three Key Points for Profile Great Wall Board Wholesale

1. Choose the manufacturer: Prioritize local Profile Great Wall Board manufacturers for easy communication and replenishment. Local Foshan manufacturers, such as ours, offer free samples and on-site technical support.
2. Check the quotation: The Profile Great Wall Board quotation must clearly include thermal break strips and spraying grades to avoid later additions. It is recommended to ask the manufacturer for a material list and section drawing.
3. Focus on installation: The insulation effect depends on the keel and insulation layer construction, which must be guided by professionals. Our company can provide construction procedure sheets; feel free to call for a free copy.
