Silica Aerogel

A SUPER-INSULATION MATERIAL WITH OUTSTANDING PHYSICAL PROPERTIES

Silica aerogel is the best thermal insulation material known to mankind. Its properties derive from its aerial structure, composed of more than 95% of air trapped in pores of nanometric size.

In terms of sustainability, our aerogel is manufactured from the most abundant resource on the planet: silica, making 25% of the Earth crust.

HIGH THERMAL INSULATION

High Thermal Insulation

  • The nanoporous structure of silica aerogels makes it the best thermal insulation material available
  • Intrinsic thermal conductivity of 0.012 W/(m.K)
FIRE STABILITY

Fire Stability

  • Mineral and non-flammable
  • Its minimum ignition temperature is 470°C
  • No particles, flaming droplets nor toxic smoke during combustion
Acoustic properties

Acoustic properties

  • Strong acoustic dampening in particular for low frequences (around 400 Hz)
  • Absorption coefficients of 0.7 to 0.9 at low and high frequencies

Lightweight

  • Very low density material (only 3 to 15 time heavier than air), less than 0.1 g.cm-3
  • Composed of 95% of air
Sustainable

Sustainable

  • Our aerogel is mainly composed of amorphous silica, allowing a long-term stability.
  • It is dimensionally stable; no shrinkage, no swelling, no settling, not even after many years.

Not a Health Hazard

  • Our aerogel is inert, non-toxic, solvent-free, as well as odor-neutral.
  • It is safe to handle and the amorphous silica structure prevents the risk of silicosis.
  • Kwark® has been assessed several times as a material that poses no risk to health and do not release VOC.

Waterproof and breathable 

  • Waterproof but permeable to water vapor
  • No corrosion and condensation issues
  • Prevents fungus or mold growth
