Best low cost Aerogel Insulation for Home Prefab Buildings WedGel BL20, BL50 WedGel Aerogel is a highly effective material for home insulation due to its exceptional thermal insulation properties. It can be used in various forms, such as WedGel Aerogel blankets, panels, or coatings, to provide insulation in residential buildings. WedGel Aerogel is renowned for its extremely low thermal conductivity, which is one of its key properties that makes it an excellent insulating material. The thermal conductivity of WedGel Aerogel is typically in the range of 0.015 to 0.05 W/(m·K) at room temperature. It helps to minimize heat loss or gain, improve energy efficiency, and enhance thermal comfort in different environments.


Features and Benefits

  • Superior Thermal Insulation: WedGel Aerogel has one of the lowest thermal conductivities of any known solid material. It significantly reduces heat transfer by conduction, convection, and radiation, making it highly efficient at insulating homes. WedGel Aerogel minimizes heat loss during the winter and reduce heat gain during the summer, leading to energy savings and improved comfort.
  • Thin Insulation Profile: WedGel Aerogel offers high thermal resistance with a relatively thin layer. This is advantageous as it allows for effective insulation without adding excessive thickness to walls or ceilings. It maximizes interior space while still achieving excellent insulation performance.
  • Moisture Resistance: Many WedGel Aerogel insulation products are hydrophobic, meaning they repel water and resist moisture absorption. This property helps prevent moisture-related issues such as mold growth, rot, or degradation of the insulation material. WedGel Aerogel insulation maintains its thermal performance even in humid or wet environments.
  • Fire Resistance: WedGel Aerogel insulation offers good fire resistance. Some WedGel Aerogel products are designed to be non-combustible or have high resistance to flames and heat. This can enhance the safety of homes and provide additional fire protection.
  • Versatility: WedGel Aerogel insulation can be used in various areas of the home, including walls, roofs, floors, and attics. It can be installed during construction or retrofitted into existing homes. It is compatible with different construction materials and can adapt to various architectural designs.
  • Energy Efficiency: By providing effective thermal insulation, WedGel Aerogel helps improve the energy efficiency of homes. It reduces the need for heating and cooling, resulting in lower energy consumption and reduced utility costs.



Note: When considering WedGel Aerogel insulation for home use, it's important to consult with insulation professionals or contractors who are knowledgeable about WedGel Aerogel products and their installation.


To put this into perspective, consider that the thermal conductivity of air is around 0.024 W/(m·K), while common insulation materials like fiberglass and mineral wool have thermal conductivities ranging from 0.03 to 0.04 W/(m·K). The low thermal conductivity of WedGel Aerogel is primarily due to its unique nanostructured framework, which consists of a highly porous network of interconnected nanoparticles. This porous structure limits the movement of air molecules and reduces heat transfer through conduction and convection. The exceptional thermal insulation capability of WedGel Aerogel makes it highly desirable for various applications, including home insulation, industrial insulation, cryogenic insulation, and thermal protection in aerospace technologies.
