For Thermal Insulating and Leveling

Advantages of LWA in Fills

  • long-term stability

  • weight reduction

  • completely safe

  • easy to handle

  • recyclable

  • non combustible


LightWeight Aggregate has great free-flowing properties due to its spherical shape and easily fills every void in beamed ceilings, floors and walls for thermal insulation. It is also very easy to cover pipes and cable ducts. Facing formwork for vertical interior insulation can be easily backfilled too. The environmentally friendly LightWeight Aggregate fill is very light, non-combustible, moisture-resistant and provides long-term stability.


LightWeight Aggregate is ideal as a lightweight, resin-bound drainage screed for roof terraces and balconies. As a cement-free and water-permeable system, problems such as efflorescence and frost damage can so be effectively avoided. LightWeight Aggregate, as a resin-bound fill, is also ideally suited as thermally insulating slope screed on flat roofs or as a lightweight marine screed.


LightWeight Aggregate cement-bound fills combine structural and thermal performance. It can be used as lightweight screed to adjust the height of floors or as levelling fill over cables and pipelines. Thanks to its low weight and moisture resistance, it can also be used on vaulted and trapezoidal steel ceilings and as a non-combustible pipe duct insulation. The easy handling and quick drying properties reduce man hours spent on the construction project.


Because of its very low thermal conductivity, its high grain strength and the resistance to heat, moisture and rodents, LightWeight Aggregate is ideal as an insulation material for all kinds of heat storage systems. The ease of use and the fact that it can be conveyed by air from bulk silo trucks are further advantages.
