Super Spacer® Non-Metal Spacer System
A key component to a window’s energy efficiency is the spacer system, which creates an insulating air space between the panes of glass that serves as a thermal barrier.
Regency 400 Series windows feature the Super Spacer – an ultra-efficient system that combines a structural foam spacer with a seal of hot melt butyl to create a “warm,” non-conductive edge. This non-metal design eliminates any metal-to-glass contact, thereby increasing the edge of the glass temperature by more than 16°- resulting in 60% more energy efficiency than a traditional box metal spacer.
