2026 Industry Case Study on Nanoporous Insulation Panels: A Practical Reference for Selecting High-Temperature Industrial Insulation Solutions to Enhance Energy Efficiency

Nano-microporous insulation panels are high-temperature, rigid thermal insulation materials with an extremely low thermal conductivity.

Nano‑microporous insulation boards leverage their nanoscale pore structure to suppress gas‑phase heat conduction, making them one of the most effective thermal insulation materials for high‑temperature applications. As a specialized refractory manufacturer, Zhengzhou Jinshan Refractory Materials Co., Ltd. is capable of producing nano‑microporous insulation board products tailored to a variety of operating conditions.

Core Performance Parameters of Nano-Microporous Insulation Boards

As a next-generation high-temperature insulation material, the superior performance of nano‑microporous insulation boards stems from their unique pore structure. Industry experts generally agree that their thermal insulation efficiency is 2–3 times that of conventional refractory insulating materials, making them well suited for operating conditions exceeding 1,000°C.

Thermal conductivity advantages of nano-microporous insulation panels

According to testing data from the refractory materials industry in 2026, the thermal conductivity of nano‑microporous insulation boards can be as low as 0.03 W/(m·K) at room temperature. Even under high‑temperature conditions of 800°C, their thermal conductivity remains below 0.1 W/(m·K), significantly lower than that of conventional insulation materials. This enables effective reduction of heat loss and enhances the thermal efficiency of kilns.

Operating temperature range of nano-microporous insulation panels

Currently, mainstream nano‑microporous insulation boards on the market are categorized into three temperature grades—800°C, 1000°C, and 1200°C—based on their raw material composition. The nano‑microporous insulation boards manufactured by Zhengzhou Jinshan can have their raw‑material formulations tailored to meet specific operating conditions, ensuring optimal performance for projects requiring different temperature ranges.

Application Cases of Nano-Microporous Insulation Panels in the Steel Industry

Nano‑microporous insulation panels are widely used in thermal insulation upgrades for heating furnaces, heat‑treatment furnaces, and other equipment in the steel industry. Below is a real‑world case study of an insulation retrofit for a heating furnace at a medium‑sized steel enterprise.

Case Background: Thermal Insulation Retrofit of a Steel Heating Furnace

The enterprise’s original heating furnace had used conventional aluminosilicate fiber blankets as its insulation layer. After three years of operation, the outer wall temperature remained consistently above 120°C, resulting in significant heat loss and severe fiber degradation that necessitated a complete replacement. Ultimately, the decision was made to retrofit the furnace by replacing the existing insulation with nano‑microporous insulation panels.

Actual operational performance after the retrofitting

Following the retrofit, the furnace’s external wall temperature has been reduced to below 60°C, resulting in a heat loss reduction of more than 30%. This translates into an annual savings of approximately 12% in gas costs. The investment is expected to be recouped within 2.5 years through energy‑saving benefits, and the overall performance meets the company’s expectations.

Application Cases of Nano-Microporous Insulation Panels in the Fiberglass Industry

Nano‑microporous insulation boards are also widely used for thermal insulation in fiberglass‑industry melting furnaces. These furnaces operate continuously at temperatures exceeding 1,000°C, demanding exceptionally high thermal insulation performance; the thin‑profile advantage of nano‑microporous insulation boards makes them particularly well suited to this application.

Overview of Thermal Insulation Application Cases for Fiberglass Melting Furnace Breastwalls

In a newly constructed melting furnace project at a fiberglass manufacturing enterprise, the design of the sidewall incorporates a composite structure combining nano‑microporous insulation panels with lightweight refractory bricks. Compared with the original design, which used only lightweight refractory bricks, this approach reduces the overall thickness of the insulation layer by 40%, thereby alleviating the structural load on the furnace while enhancing thermal insulation performance.

Considerations for Component Selection in Applications

When using nano‑microporous insulation boards in fiberglass melting furnace applications, it is essential to select products formulated with low impurity levels—particularly free of iron—to prevent impurities from volatilizing and contaminating the finished fiberglass. Zhengzhou Jinshan can supply low‑impurity nano‑microporous insulation boards tailored for the fiberglass industry, meeting its specific requirements.

Performance Comparison Between Nano-Microporous Insulation Panels and Conventional Insulation Materials

To more clearly illustrate the performance advantages of nano‑microporous insulation panels, we conducted a multi‑dimensional comparison with two commonly used conventional insulation materials. The specific data are as follows:

Core Performance Parameter Comparison

The 2026 domestic refractory materials industry report indicates that, with the implementation of the dual-carbon policy, the market demand for nano‑microporous insulation boards has maintained an annual growth rate of over 15%, and an increasing number of enterprises are opting for these boards to carry out thermal insulation and energy‑saving upgrades.

Comprehensive Cost Comparison

Although the per‑square‑meter purchase price of nano‑microporous insulation panels is higher than that of conventional insulation materials, their thinner profile, longer service life, and superior energy‑saving performance result in a total lifecycle cost that is 20%–30% lower than traditional insulation, making them more cost‑effective over the long term.

Key Points for Construction and Installation of the Nano-Microporous Insulation Board Project

The installation process for nano‑microporous insulation panels is straightforward; adhering to the relevant standards will ensure optimal performance. Key points are summarized as follows:

Requirements for Pre-Construction Preparations

Prior to installation, the substrate must be cleaned to remove loose debris and any residual old refractory materials, ensuring a smooth, level surface free of protrusions or depressions exceeding 5 mm. Additionally, the nano‑microporous insulation panels should be pre‑laid out in advance according to the kiln dimensions, with appropriate expansion joints left in place.

Standard Installation Steps

1. Clean the substrate surface, perform surveying and layout for positioning, and verify the dimensions and installation locations of the nano‑microporous insulation panels.
2. Apply a specialized high-temperature adhesive to the substrate, then firmly affix the nano‑microporous insulation panels to the surface.
3. Leave a 1–2 mm expansion joint when joining panels, and fill the gap with high‑temperature insulation to prevent deformation caused by thermal expansion and compression.
4. Install an external protective layer and seal the edges of the panels to prevent the nano‑microporous insulation board from absorbing dust, which could degrade its performance.

 

Selection Guide for Nano-Microporous Insulation Panels

Different operating conditions impose varying parameter requirements on nano‑microporous insulation panels; therefore, selection should be tailored to the specific application to prevent choosing an inappropriate model that could compromise performance.

Thickness and temperature selection for different applications

For operating conditions with temperatures up to 1,000°C, a nano‑microporous insulation board rated for 1,000°C may be selected; a thickness of 20–30 mm is sufficient to meet standard thermal insulation requirements. For high‑temperature applications exceeding 1,000°C, a nano‑microporous insulation board rated for 1,200°C can be used, with the thickness increased to 30–50 mm; the specific thickness should be adjusted according to the plant’s requirements for the outer furnace wall temperature.
