SL-120 Series is our most advanced sliding thermal break system. The internal and external profile sections are designed to be connected without the use of continuous crimping. It can be connected manually with the use of special internal polyamide connectors which are distributed equally then tightly fixing it with an external continuous polyamide strip. These connectors are the main key to meet the ESTIDAMA requirements. With our advanced air system rest assured that the full thermal performance will be reached by ensuring there will be no air leakage.
