The remarkable fire-proofing and insulating properties of Hemalite coupled with its weight saving value make it much more efficient than any other light weight in the preparation of insulating concrete.

The thermal insulating properties of Hemalite prevent the ingress of heat from the sun’s rays during summer and reduce heat loss during winter, consequently, expansion and contraction in buildings is minimized and concrete roof slabs are protected from cracking that take place when exposed to temperature changes.

For roofs of large area, falls can be effected without appreciably adding to the total weight of the roof.
