closed cell

  • High thermal insulation properties - The large number of closed cell pores, as well as the air enclosed therein, are responsible for the excellent R- value of the material.
  • Very water permeable - GLAVEL’s cells remain dry, interstitial spaces allow water to drain off .
  • Excellent frost resistant properties and protection against frost heave of foundations/roadbeds
  • Resistant to nearly all acids, bases, bacteria, frost, aging, rotting, wetness and rodents.
  • Environmentally friendly recycled glass with excellent energy balance.
  • Inert material when exposed to soil, qualifies as “clean fill”
  • Lightweight - bulk density of foam glass is only one twentieth of the other weight of aggregates.
  • The low specific weight of 9.5 lbs./CF(bulk volume).
  • Non-combustible - Glass does not burn.
