Super Spacer Triple Glaze
A spacer keeps a window’s dual glass panes the correct distance apart for optimal airflow between panes. Too much or too little airflow can affect the insulating glass efficiency. The design and material of the spacer can also make a big difference in the ability to handle expansion and contraction and thus reducing condensation.
