Closure system – sleeves and plugs
Uniform quality and good gas concentrations for IG units can only be assured with an effectively sealing closure system. The sleeve and plug system, as well as signal plugs, have been proven millions of times over.
HELANTEC only offers products that are tested and that have been checked for material compatibility. Bear in mind that adapted closure systems are necessary for different spacer materials.
We would be pleased to advise you in this regard. Rely on our experience and quality – cheap can sometimes become very expensive.
