Spex•Lite® Fills More Volume Than Ordinary Fillers

Spex•Lite® Solid Air weighs a lot less than ordinary lightweight fillers. Because of how lightweight Spex•Lite® Solid Air is, it can fill a lot more space, or volume, than other lightweight aggregates given the same weight. Because material is most commonly bought by weight, you can save a lot of money by using  Spex•Lite® Solid Air. 


Benefits of using Spex•Lite® Solid Air:

  • Decrease weight of system
  • Fill more void space with less weight
  • Doesn't break into abrasives under shear
  • Absorbs minimal water
  • Decreases volume cost of overall system in most cases
  • Improves performance of system in most cases


For example, glass microspheres can weigh about 7.8 pounds per cubic foot (pcf). Spex•Lite® Solid Air weighs about 1.0 pound per cubic foot (pcf). So, compared to common glass microspheres, Spex•Lite® Solid Air is ~7.8 times more efficient as a volume filler.
