DarQ Heat & Sound Insulation Systems
Improved solutions to heat problems are constantly required in most 29 applications and processes starting from (-) 200 °C to 1750 °C to 30 improve operational performance and durability of equipment, 31 reduce heat loss, save energy, save space, and protect environment.
Finding heat insulation system with highest insulation performance 33 (lowest thermal conductivity), high mechanical strength, high service 34 temperature, easiest application, long lasting, and lowest cost is 35 almost impossible. However, thanks to the modern insulation 36 technologies and latest developments in combining wide range of 37 technical properties making it available a wide range of insulation 38 materials & systems to achieve optimized high performance at low 39 cost and long lasting insulation systems at extremely low 40 maintenance cost.
Heat insulating materials usually have a total porosity of at least 42 45%, in practice mostly from 60 to 90%, and in extreme cases up to 43 99%. Besides low thermal conductivity, high porosity causes reduced 44 mechanical strength, high gas permeability and low corrosion 45 resistance. The thermal conductivity not only depends on the total 46 porosity of the material, but also on the pore size and shape, the 47 structure composition and the mineralogical composition.
Depending on temperature, the factors responsible for the flow of 49 heat – solid state conduction, convection and radiation – vary in 50 influence. Maximum pore diameters of < 1 mm are necessary. Micro 51 -porous insulating materials with pores < 0.1 μm have the lowest 52 thermal conductivity.

High Performance Thermal Insulation Systems
Insulation serves as a vital property for materials, providing resistance against the transfer or transmission of various forms of energy, such as sound, heat, electricity, fire, cooling, and vibrations. Essentially, insulation acts as a barrier, hindering the transmission of electricity, heat, moisture, shock, or sound.
Creating Barrier to Thermal Heat Losses
Thermal insulation of any material—be it organic or inorganic—pertains to its resistance to heat transfer or transmission. Understanding insulation materials necessitates a grasp of the physics behind heat transfer.
Heat transfer can manifest through conduction (both solid and gaseous), convection, and radiation. Typically, the overall heat transfer arises from the combined effects of these mechanisms, with the temperature difference serving as the driving force. In environments like furnaces and low-mechanical-load plants without corrosion stress, the utilization of lightweight heat-insulating materials has largely supplanted heavy designs reliant on dense, refractory materials.
Heat insulating materials serve as integral components in the refractory linings of industrial thermal plants, with the primary aim of mitigating heat losses. Leveraging the low thermal conductivity and the thermal capacity of air, these materials are engineered to minimize the transfer of heat. Typically boasting a total porosity ranging from 60% to 90%, and in some instances even up to 99%, heat insulating materials also exhibit notable characteristics such as reduced mechanical strength, high gas permeability, and limited corrosion resistance 88
Key advantages of DarQGel Aerogel insulation include:
- Outstanding thermal insulation: DarQGel Aerogel insulation boasts an exceptionally low thermal conductivity, often 2-4 times lower than traditional materials like fiberglass or foam. This remarkable characteristic enables it to effectively diminish heat transfer and minimize energy losses.
- Thin and lightweight: DarQGel Aerogel insulation offers equivalent or superior insulation performance compared to alternative materials but at a fraction of the thickness. This feature allows for thinner insulation profiles, which proves advantageous in scenarios where space constraints or weight reduction are priorities.
- Hydrophobic properties: DarQGel Aerogel exhibits inherent resistance to moisture, preventing water absorption and ensuring sustained insulation performance even in damp or humid environments.
- Fire resistance: DarQGel Aerogel insulation is intrinsically fire-resistant, rendering it a safer option for insulation applications. It aids in slowing down the propagation of flames and provides additional protection in the event of a fire outbreak
Features & Benefits of DarQGel Aerogel Coatings
Superior Thermal Insulation
DarQGel Aerogel paint incorporates DarQGel Aerogel particles renowned for their exceptional thermal insulation properties. By minimizing thermal conductivity, these particles reduce heat transfer through coated surfaces, leading to improved energy efficiency and enhanced thermal comfort in buildings and other applications.
