Proper building energy design and insulation installation are critical to ensuring optimal energy efficiency and reducing greenhouse gas emissions . Rock wool is also suitable for extreme conditions as it maintains excellent insulating properties in both extremely low and extremely high temperatures.

ZRD Roof Rock Wool Board 1. High fire rating: A1 class fireproof material;2. High mechanical strength: high compressive strength and point load, avoiding damage caused by trampling;3. Good thermal insulation performance: it has excellent thermal conductivity and saves energy consumption of buildings;4.

Good acoustic performance: provide excellent sound insulation and sound absorption effects;5. Good durability: it has excellent dimensional stability and high water repellency, and has the same service life as the roof;ZRD Exterior Wall Rock Wool Board 1.

Satisfy the highest fire protection level, fire protection class A . 2. Non-combustible, does not release toxic fumes, green performance . 3.

The compressive and tensile strength meet the requirements of the external wall insulation standard, and the strength standard is highly consistent with the external wall standard. 4. Good thermal insulation performance and long-lasting stability. 5.

With excellent air permeability and convenient construction , it has become the preferred choice for building exterior wall construction parties.

ZRD Rock Wool Board for Curtain Wall Rock wool panels for curtain walls are used in commercial and residential buildings to improve interior comfort and increase energy efficiency.

There are various ways to increase interior wall insulation, each of which can contribute to reducing heat loss, increasing acoustic performance, or improving fire safety . Proper building energy design and insulation installation are critical to ensuring optimal energy efficiency and reducing greenhouse gas emissions.

Rock wool is also suitable for extreme conditions as it maintains excellent insulating properties in both extremely low and extremely high temperatures.

Rock wool products have the characteristics of green environmental protection, low thermal conductivity, high temperature resistance, heat insulation, sound insulation, flame retardant, and antifreeze. Thermal insulation and sound insulation projects in construction, transportation, shipbuilding and other industries.

Nanjing Zhongrunda has always been adhering to the core purpose of " doing our best to provide customers with high-quality rock wool products ", promoting the high-quality sustainable development of environmental protection and energy-saving materials in the new era of society, and striving to provide what it can for a low-carbon society and socialism with Chinese characteristics in the new era.

shelp. Company Vision: To become a high-end rock wool integrated service provider in China and to be a pioneer in the field of new building materials in China. The company's core values: quality, service, efficiency, responsibility, innovation.

In recent years, in order to open up the international market, Nanjing Zhongrunda has determined the core goal of international market development of " subdividing the vertical field of rock wool and broadening the new field of thermal insulation materials ".

Subdividing the vertical field of rock wool is mainly to segment the market. In the vertical subdivision fields such as rock wool shell, rock wool felt, and agricultural rock wool, we will dig deep into the target customers.

Our rock wool felt rolls, rock wool pipe shells, and agricultural rock wool are exported to Southeast Asia, North America, South America, and the Middle East .

Especially the Southeast Asian market is the core market of Nanjing Zhongrunda New Materials, and is deeply loved and trusted by customers from the Philippines, Vietnam and other countries. ZRD rock mineral wool products are made from natural rock such as basalt and dolomite .The natural rock are me
