Granulhik
High Performance Aerogel Granules
Granulhik is a translucent, high-performance silica aerogel granule designed for applications requiring both superior thermal insulation and light transmission. Unlike fine powders, Granulhik features a larger, millimetric particle structure that allows for excellent light diffusion while blocking heat transfer.
It is the ideal filling material for daylighting systems (polycarbonate panels, architectural glass), creating energy-efficient buildings filled with natural soft light. Additionally, its robust granular structure makes it a perfect lightweight aggregate for high-performance insulation plasters and cavity wall insulation.

Key Benefits
Light Transmission & Diffusion
Allows natural daylight to pass through while diffusing it evenly, preventing glare and hot spots in architectural glazing.
Outstanding Thermal Insulation
Provides high insulation performance (λ ≤ 0.019 W/mK), significantly improving the U-value of glass and plastic panels.
Sound Insulation
The porous granular structure effectively dampens noise, improving acoustic comfort in buildings.
Hydrophobic Durability
Repels water and moisture, ensuring consistent performance and preventing mold growth within panels or walls.
Non-Combustible
Inorganic composition ensures high fire safety and does not contribute to smoke generation.
Applications
Daylighting Systems
Insulating filler for multi-wall polycarbonate sheets, U-channel glass, and skylights.
Insulation Plasters
Lightweight, breathable aggregate for interior and exterior thermal plasters.
Cavity Injection
Loose-fill insulation for double-wall masonry and narrow gaps.
Translucent Roofing
Tensile membrane structures and stadiums requiring light and insulation.
Safe Touch Insulation
Granular filling for complex industrial shapes where blankets cannot fit.
