We start with the most efficient spacer system for our High Performance glass.  Super Spacer is recognized as the best glass spacer system on the market today.  Only this spacer gives you the warmest glass edge possible.
  It too is the best spacer for retaining argon gas. This revolutionary non-metal spacer is produced with two seals PLUS a vapor barrier. Unlike all other insulated glass units that are made with a single seal, ours has three. We know with three seals we will hold the argon gas in, we can't say that about other systems.

  It is also the best spacer for minimizing, if not eliminating, the chance for condensation.  Moisture not only can damage your home's walls but also provides a source and a place for dangerous bacteria and mold to grow.  That is why windows made with Super Spacer are called 'Health Smart' windows - because they really are!
