Snap-on face covers enable separate interior/exterior finishes for aesthetic and/or economic reasons. The system is glazed from the interior to reduce field labor with options for outside re-glazing. Optional head and sill anchors allow ease of installation for punched openings. Two sided structural silicone glazing at vertical mullions is also available as an option.
