Expanded clay granules offer good insulation, they are lightweight and heatproof.
Applications:
Insulation, especially on roofs and for so called "Green Roofing Systems".
Heat proofing in kilns, stoves and ovens.
As a component in lightweight concrete.
A use which we find facinating is as mini floating pontoons on which honey bees can land when being fed sugar and water during times of natural food shortage - we think this takes First Prize for the most unusual application of any of our products !!
Horticulture
Expanded clay pellets are pH neutral, and are porous, yet have the ability to store water. The gaps between the pellets provide good aeration root systems.
Expanded clay pellets are used as a substrate in hydroculture / hydroponics, and as a soil additive. They can also be spread as a top dressing (mulch) around plants to retain moisture and prevent weed growth.
