The JEB 3Seal HM+ spacer offers significant aesthetic and energy-efficient advantages. The high-modulus silicone secondary seal minimizes PIB migration, providing clear, straight sightlines. It also offers 35 percent higher design strength, allowing for a narrower air cavity in an IGU, and 10.4 percent more argon gas retention than standard sealants, based on ASTM 2190 testing. An IGU incorporating the JEB 3Seal HM+ spacer will retain its argon gas longer over other insulating glass systems, maximizing energy savings and extending the units service life.
