Safety and environmental protection of roof insulation materials: looking at industry development from the Qiqihar collapse accident
The tragedy in Qiqihar Middle School Gymnasium
On July 24, 2023, a serious collapse occurred in a middle school gymnasium in Qiqihar City, resulting in the unfortunate death of 11 people. Preliminary investigation results showed that the cause of the accident was that a large amount of perlite insulation material was piled on the roof, which caused the structure to be overloaded. This incident not only shocked the country, but also triggered widespread concern in the construction industry about the safety of roof insulation materials.
Safety issues of thermal insulation materials
Roof insulation materials are an important part of building energy conservation, and their safety performance directly affects the structural stability and service life of the building. As a lightweight, porous natural material, perlite has good thermal insulation properties and low cost, and is widely used in roof and wall insulation. However, the packing density of perlite is relatively high. When stacked in large quantities, it may cause huge pressure on the building structure, thus causing safety hazards.
The New Zealand Chinese Herald website once reported that the invisible killer of houses has been lurking for a long time and has no solution, including improper use of insulation materials. This shows that the safety issue of thermal insulation materials is not limited to China, but is a challenge faced by the global construction industry.
Balance between environmental protection and performance
As the environmental awareness of the construction industry continues to increase, more and more new insulation materials are being developed and applied. For example, Titanium Valley Technology has made significant progress in the field of titanium building materials with its complete industrial chain system. The company not only focuses on the environmental performance of the material, but also takes into account its safety and economic benefits.
However, the promotion and application of new materials does not happen overnight. The selection of materials in the construction industry usually involves a variety of factors, including cost, construction difficulty, maintenance cycle, etc. Following this logic, how to control the cost and construction risks while ensuring the performance of thermal insulation materials is a problem that construction companies and material suppliers need to jointly solve.
Design and construction synergy
The green house project was designed by the Dutch architect firm architectenbureau cepezed. The project not only considered the environmental protection of the roof insulation materials, but also ensured the rational use of materials and the safety and stability of the structure through refined design solutions. This successful case shows that the safety issues of thermal insulation materials often need to be fully paid attention to during the design stage.
Architectural designers and construction parties should work together to formulate scientific and reasonable construction plans to ensure the safety and reliability of insulation materials during use. Full consideration in the design stage and strict management of the construction process are effective means to prevent accidents like Qiqihar.
The importance of regulation and regulation
The collapse of the Qiqihar Middle School gymnasium, in addition to problems with the materials themselves, also exposed deficiencies in construction supervision and code enforcement. The application of new materials must have strict standards and supervision systems to ensure their reliability and safety in actual projects. The construction industry should strengthen the formulation and implementation of industry standards and implement stricter supervision of the use of insulation materials.
The establishment and implementation of industry standards can not only regulate the market, but also promote technological innovation and form a virtuous cycle. All stakeholders should actively participate in this process and jointly promote the healthy development of the industry.
Conclusion
The safety and environmental protection of roof insulation materials are core issues that the construction industry must pay attention to. In the face of the continuous emergence of new materials, all aspects of design, construction, supervision and specification need to work together to ensure that thermal insulation materials will not cause safety hazards while improving building energy efficiency. The tragedy in Qiqihar should serve as a wake-up call for the industry, prompting us to treat every construction project more prudently.
In the future, how construction companies can efficiently utilize new thermal insulation materials while ensuring safety will be the focus of attention both inside and outside the industry.

What are the characteristics of perlite insulation materials?
Perlite is a lightweight, porous natural material with good thermal insulation properties and low cost. However, its packing density is high, and when stacked in large quantities, it may cause pressure on the building structure and cause safety hazards.
How to balance the environmental protection and cost of insulation materials in buildings?
The promotion and application of new materials need to consider many factors, including cost, construction difficulty, maintenance cycle, etc. Construction companies and material suppliers need to work together to ensure that costs and construction risks are controlled while improving environmental performance.
How do design and construction work together to ensure the safe use of insulation materials?
Architectural designers and construction parties should work together to formulate scientific and reasonable construction plans to ensure the safety and reliability of insulation materials during use. Full consideration in the design stage and strict management of the construction process are effective means to prevent accidents.
Why does supervision of new thermal insulation materials need to be strengthened?
The application of new materials requires strict standards and regulatory systems to ensure their reliability and safety in actual engineering.
