Application of Aerogel Insulation Coating for Existing Building Energy Upgrades
This reference case is based on a large-scale residential retrofit project in Yangquan, Shanxi, China, demonstrating the practical use of aerogel insulation coating systems as a thin-layer alternative to conventional insulation solutions in building energy upgrades.
The project covers multiple residential communities and hundreds of buildings, with a total retrofit area exceeding one million square meters. Through building envelope upgrades, it helps improve thermal performance, indoor comfort, and overall façade condition.
In this project, a thin-layer aerogel coating system was applied to exterior walls, illustrating the feasibility of a thin-layer, high-efficiency approach that significantly reduces system thickness compared to traditional 50–100 mm insulation systems.
For buyers evaluating thin insulation systems for retrofit, especially where space, façade modification, or occupancy constraints apply, this case complements the technical information available in our Technical Data Sheets and additional documentation in the Resources section.
Retrofit projects usually require minimal disruption to existing structures, compatibility with original substrates, and fast execution under real occupancy conditions, making conventional thick-board systems difficult to apply in many cases.
Projects at this scale require stable material supply, consistent product quality, and coordinated on-site execution.
This process forms a continuous insulation layer with a total reference thickness of approximately 2 mm.
Compared with traditional external insulation systems in the 50 to 100 mm range, the total system thickness can be reduced from 50–100 mm to approximately 2 mm, minimizing façade build-up, structural load, and installation complexity.
For product-specific values, buyers can review the corresponding Technical Data Sheets or contact Airgeltech for application discussion, making it particularly suitable for existing buildings where additional thickness, façade modification, or structural load increases are restricted.
The coating is applied layer by layer using spraying or roller methods, forming a continuous insulation system on the wall surface. Combined with rope access equipment and lifting platforms, the process is well suited to high-rise façade retrofit conditions, especially where scaffold installation is limited or façade access is constrained.
In similar practice scenarios, a single residential building can often be completed within approximately 7 to 10 days, allowing retrofit work to proceed without requiring occupants to relocate, which is a key requirement in urban renovation projects.

These figures are presented as typical reference outcomes from similar projects, indicating potential energy efficiency improvements and indoor comfort enhancement under suitable conditions. Actual performance depends on building condition, substrate preparation, local climate, and system design.
Installation and on-site construction are carried out by contractors or project execution teams.
Aerogel insulation coating is suitable for existing residential and commercial buildings where conventional thick insulation systems are difficult to install, including retrofit projects, urban renewal programs, and facade energy upgrades.
Aerogel insulation coating can be applied at a total thickness of approximately 2 to 5 mm, depending on system design and performance requirements. This is significantly thinner than traditional insulation systems.
In most retrofit applications, aerogel coating can be applied directly onto prepared existing wall surfaces without demolishing the original finish, reducing construction disruption and waste.
In similar projects, a single residential building can typically be completed within approximately 7 to 10 days, depending on building size, weather conditions, and site accessibility.
Yes, aerogel coating can be used as part of a hybrid insulation system. It is often used as a standalone thin-layer solution for retrofit projects or combined with other materials depending on thermal performance targets and project conditions.
