Warm edge spacers

Avery Dennison delivers high barrier multilayer laminates to aid the production of warm edge spacers, which help to maintain the performance of insulating glass units (IGUs) such as double and triple glazed windows. Our adhesive tape solutions for window spacers are an essential part of creating energy efficient IGUs, helping to keep glass panes separated and warm edge spacers moisture tight and allow no argon gas transmission for maximum effectiveness.
