Warm Edge Insulating Glass Spacer | Architectural Glass Fabricators
JEB 3SEAL® HM + Warm-Edge Spacer High-Performance, Warm-Edge Insulating Glass Spacer with High-Modulus Structural Silicone Designed to meet the toughest commercial glazing demands, the JEB 3Seal HM+ spacer features triple seal technology, including an improved secondary seal made out of high-modulus silicone, as well as a hot-applied captive polyisobutylene (PIB) primary seal and a pre-applied acrylic adhesive for spacer to glass bonding. The improved JEB 3Seal HM+ spacer offers significant aesthetic and energy-efficient advantages over traditional IGU spacers. 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.
