Effect Analysis of Foam Glass Applied to Exterior Wall Insulation


Foam glass is an inorganic, non-metallic material produced from cullet, foaming agents, modified additives, and foaming accelerants. It undergoes fine grinding, uniform mixing, and then melting and annealing at high temperatures to create a lightweight, porous structure with excellent thermal insulation properties.

In recent years, several high-profile building fires have highlighted the dangers of using flammable or combustible external insulation materials. Incidents such as the fire at Nanjing Zhonghuan International Plaza, Harbin Jingwei 360-degree Gemini Building, Jinan Olympic Sports Center, Beijing CCTV New Site Affiliated Cultural Center, Shanghai Jiaozhou Teacher Apartment, and Shenyang Dynasty Wanxin Building have resulted in significant loss of life and property damage. As a result, the use of flammable exterior insulation has become a major fire hazard, with these types of fires increasing in frequency and severity.

With growing awareness of energy conservation and environmental protection, the Chinese government has been actively promoting policies that improve living standards and reduce energy consumption. Building energy efficiency has become a key focus, and the adoption of high-performance, fire-resistant materials like foam glass panels is being encouraged. These A-grade insulation materials offer superior fire resistance, thermal insulation, and energy-saving benefits, making them ideal for exterior wall applications. By integrating such materials into construction projects, we can significantly enhance building energy efficiency, reduce carbon emissions, and create safer, more comfortable living environments.

While traditional insulation materials have long played a vital role in improving indoor comfort, the evolving demands of modern architecture and rising living standards have led to higher expectations for insulation performance. Advancements in technology have driven improvements in material properties, leading to more durable, efficient, and environmentally friendly solutions. As winter approaches, the importance of wall insulation and heating has never been greater. Effective insulation methods—both internal and external—are essential for maintaining a stable indoor climate and reducing energy waste.

Technological progress has greatly enhanced the value and performance of foam glass panels. As global innovation continues to rise, resource utilization rates are improving, and building materials are becoming more sustainable and efficient. The market for eco-friendly, energy-saving coatings and insulation solutions is expanding rapidly, reflecting a growing commitment to environmental protection. This trend ensures that future winters will be warmer, more energy-efficient, and more comfortable for everyone.
