Slate Flakes

A historic product of Carlac Minerals, slate flakes are crafted through selective grinding of Brioverian slate schist. Their lamellar structure ensures an ideal and uniform coverage of bituminous roofing membranes. Available in multiple particle sizes (5 variations), they provide superior protection.

Technical characteristics

Lamellar slate flakes are intended for roofing applications on bituminous membranes.
Their properties are numerous:

Protective: They protect against UV rays and ensure the durability of the membranes by preventing their deterioration.
Thermal influence: Depending on the color, they reflect heat (white) or retain it (dark colors)
Aesthetics: They enable roof coloring
