Thermoflex Dual Seal Spacer is also available for dual seal application.  

The design differs to standard Thermoflex Warm Edge Spacer in that it has steps along its edges for the application of Polyisobutylene (PIB) primary sealant.  The application of both a primary and secondary seal offers all the advantages of a traditional dual seal tube spacer system.  This spacer is sometimes referred to as a triple seal spacer due to its side tape which acts as a handling aid bonding the spacer to the glass in conjunction with PIB primary seal.

All Thermoflex Warm Edge Spacers are made with a premium composition of pre-desiccated flexible foam.  All spacers also have a unique moisture barrier tape to maximise their thermal efficiency whilst minimising the ingress of moisture and loss of gas for improved longevity within sealed units.
