Spectre Window 31 in. x 23.25 in. Frameless Glass Block Replacement Window, Privacy Patterns
Reviewed pricing, lead time, freight, and final configuration are confirmed during quote review before order release.
Each panel arrives factory-mortared and ready to set, in wave, clear, diamond, or ice patterns. Fixed panels wall off drafts entirely; vented configurations add a hinged vent for airflow, and dryer-vent configurations carry a 4 in. appliance duct pass-through. Glass block resists forced entry far beyond a sashed window, which is why these panels anchor basement security programs.
Highlights
