Security Glass
Double-glazed glass and Low-E
Two panes separated by a sealed cavity. Double-glazed units (IGUs) improve thermal and acoustic comfort; a Low-E coating cuts heat transfer further.
Construction
- Outer pane6 mm
- Sealed air cavity12 mm, optional argon fill
- Inner pane6 mm, optional Low-E coating
