Patented Super ​Spacer® Technology

  • Inst-I-Glass uses Super Spacer® warm edge technology in our insulated glass units: 
  • Our all-foam spacer blocks the heat escape path and provides one of the best thermal performers in the industry. 
  • Our customers report a noticeable drop in outside noise.​
  • All-foam formula offsets the effects of expansion and contraction from temperature changes, resulting in less seal failures and stress cracks.

We got a recommendation from a neighbor to call Instiglass and we couldn't be happier with the result. They look fantastic (and we saved thousands of dollars by not replacing the entire window). Marty was super friendly and is very good at his job. Highly recommend.”
