Great Wall Board Thickness Selection for Engineering: A Case Study on Insulation Efficiency

This summer, continuous high temperatures in Guangdong posed extreme insulation requirements for a commercial complex exterior wall decoration project. As the procurement manager, I experienced the entire process from material selection to installation. The choice of engineering Great Wall board thickness specifications directly affected the final outcome.

Project Background

The project is located in Foshan, with a building area of approximately 20,000 m². The exterior wall needed to be both decorative and insulating. The client required weather-resistant, fireproof materials that could lower indoor temperatures. After multiple discussions, we decided to use Great Wall profile aluminum, utilizing the air layer for insulation.

Material Selection

Great Wall boards come in various thickness specifications: common options are 1.0mm, 1.2mm, and 1.5mm. We ultimately chose 1.2mm because 1.0mm is too thin and prone to deformation, while 1.5mm is too costly and heavy. According to engineering Great Wall board thickness specification standards, 1.2mm meets wind pressure resistance requirements and offers the best cost-performance ratio. We contacted Great Wall board manufacturer——广东省问鼎建材贸易有限公司. They provided detailed Great Wall board quotes and samples, with stable supply covering the entire Guangdong province.

Construction Highlights

During installation, we used thermal break insulated keels with backing panels to create an air layer. The overlap joints of the Great Wall boards had 5mm gaps to accommodate thermal expansion. We paid close attention to flatness, checking every 3 meters with a string line, and kept nail spacing under 300mm. The technical staff from 广东省问鼎建材贸易有限公司 provided on-site guidance, preventing common warping issues.

Effect Display

After completion, the exterior wall was smooth and the lines were clean. Tests showed that on summer afternoons, the surface temperature of the wall was 8-10°C lower than ordinary aluminum panels, and indoor air conditioning energy consumption noticeably decreased. The client was very satisfied with the results.

Procurement Summary

Choosing 广东省问鼎建材贸易有限公司 was not only because of their reasonable Great Wall board quotes, but also because their scale ensures supply stability. If you have similar needs for engineering Great Wall boards, feel free to contact us at 18575812635, or click the form below to get a quote.
