With the continuous upgrading of building energy efficiency standards, more and more old buildings need energy-saving renovations, and external wall insulation is a crucial aspect of improving building energy efficiency. Aerogel felt, as a new type of insulation material with extremely low thermal conductivity, has significant advantages in the field of energy-saving renovations.

Aerogel felt possesses ultra-low thermal conductivity, achieving excellent insulation performance even at very thin thicknesses. This means that during building energy-saving renovations, insulation upgrades can be completed within a relatively small space without significantly occupying interior space or altering the exterior facade structure. Furthermore, aerogel felt is soft, lightweight, and easy to install, making it suitable for various scenarios such as complex walls and irregular structures.

Its stable weather resistance, flame-retardant properties, and long service life make aerogel felt a high-potential material for energy-saving renovations of old buildings. With the accelerated pace of urban renewal, aerogel felt will play an important role in more energy-saving projects, providing buildings with efficient and reliable thermal insulation solutions.
