Elastilon Lock differs from the previously mentioned types in that the adhesive layer is applied to both sides. It therefore only allows for minimal tolerances. It is applied in combination with very stable parquet systems, such as the advanced double-layer parquet or prefab pattern floors by, such as Cosmo, Italy, or the laminate flooring from Tilo in Austria. Together with under-floor heating, the parquet floor applied in this manner is a fully integrated part of the under-floor heating system, unlike glued systems, which are applied in spots. Impact noise is also reduced to a whisper.

Elastilon Lock should only be used by highly qualified installers.
