Granulhik
Translucent Silica Aerogel Granule
Granulhik is a translucent nanoporous silica aerogel granule developed for applications where thermal insulation, low density and light diffusion are required in one material format.
Product Description
Unlike fine powders, Granulhik has a millimetre-scale granular structure that can be used as an insulating filler in daylighting systems, translucent panels, insulation plasters, cavity fills and complex technical shapes. Granulhik combines low thermal conductivity, hydrophobic behaviour and high porosity with a semi-transparent appearance, making it suitable for building-envelope and specialist formulation applications.
