Great Wall Large Board vs. Standard Aluminum: Thermal Performance Comparison for Summer Engineering Procurement

Summer high temperatures are approaching, and the thermal performance of engineering aluminum is a key factor in procurement decisions. This article compares the insulated aluminum provided by Great Wall Large Board Engineering Aluminum Procurement Station with standard aluminum, helping engineering procurement professionals select materials scientifically.

Why Must Engineering Aluminum Consider Thermal Insulation?

During summer in Guangdong, continuous high temperatures cause air conditioning to account for over 60% of building energy consumption. Standard aluminum has a thermal conductivity of up to 203 W/(m·K), directly transferring heat indoors and increasing electricity costs. In contrast, the insulated aluminum promoted by Great Wall Large Board Engineering Aluminum Procurement Station uses PA66 nylon thermal break strips to block the thermal bridge, with a thermal conductivity of only 3.0 W/(m·K), providing significant energy savings.

Comparison: Great Wall Large Board Insulated Aluminum vs. Standard Aluminum

• Material Structure: Great Wall Large Board insulated aluminum uses high-precision 6063-T5 aluminum alloy with fluorocarbon spraying; standard aluminum is mostly 6063-T5 without thermal break strip.
• Performance Parameters: Insulated aluminum heat transfer coefficient K=2.8 W/(m²·K), air tightness class 8; standard aluminum K=4.5 W/(m²·K), air tightness class 6.
• Price Range: Great Wall Large Board quote approx. 580-720 RMB/m² (including thermal break strip), standard aluminum approx. 350-450 RMB/m².
• Service Life: Insulated aluminum weather resistance 25 years, standard aluminum 10-15 years prone to corrosion.

Performance Testing: Data Comparison Under Summer High-Temperature Conditions

Under simulated Guangzhou summer conditions of 35°C outdoor and 26°C indoor air-conditioned environment, tested according to GB/T 5237.6-2017:

• Surface temperature of insulated aluminum: 32.5°C, standard aluminum: 41.2°C;
• Indoor heat flux: insulated 13.2 W/m², standard 28.7 W/m²;
• Daily electricity saving approx. 0.15 RMB/m² (calculated over 8 hours).

Cost-Benefit Analysis: Comprehensive Cost and Return

The initial investment for Great Wall Large Board insulated aluminum is 40% higher than standard aluminum, but the annual energy saving is about 50 RMB/m², recovering the cost difference within 5 years. Moreover, standard aluminum needs replacement after 10 years, while Great Wall Large Board Engineering Aluminum Procurement Station provides stable supply and a 15-year warranty, offering long-term cost advantages.
