Lecaterm-Block
Lecaterm-blocks are a sandwich block that combines the strong leca lightweight clinker concrete with high-insulation foam plastic. The cores of foam plastic are fitting with dovetail grooves and casting-in ensures they are permanently locked into the jambs.
Leca lightweight clinker concrete is made with the same material properties as the solid leca-block 600.
The foam plastic is expanded polystyrene (EPS).
