JOINLEADER THERMAL SPACER Description Joinleader spacers are manufactured of stainless steel combined with a high quality plastic polypropylene as a strengthening and insulating material due to its low heat conductivity.. The perfect symbiosis of both materials allows only a very low heat transfer while guaranteeing high tightness against gas leakage and humidity Therefore high quality and safety are guaranteed for the production of insulating glass units Advantage --Distinctly improved UW values --Large reduction of condensation and mould --High strength ,can be applied in various windows doors and curtain wall projects --The linear expansion coefficient of JOINLEADER spacer is very near to glass so it can keep the lifetime of IGUs much longer --Excellent optical characteristics --JOINLEADER thermal spacer are bendable and processable on all standard bending machines. any shape is possible Specification Article Dimensionwidth 8A 7.5mm 10A 9.5mm 12A 11.5mm 14A 13.5mm 15A 14.5mm 16A 15.5mm 18A 17.5mm 20A 19.5mm 22A 21.5mm 24A 23.5mm Color Dark brown=RAL8016 Light brown=RAL8003 Light grey=RAL7035 Dark grey=RAL7040 Black=RAL9005 White=RAL9016,
