High Impact Resistant Polycarbonate Window Sheet, 1/8"X12"X18"

The 121818PC High Impact Resistant Polycarbonate Window Sheet is a clear, impact-modified polycarbonate panel designed for security glazing, machine guards, storm panels, and protective barriers. Measuring 1/8" thick × 12" × 18", this high-impact grade sheet delivers exceptional toughness and optical clarity, transmitting approximately 88–92% of visible light—close to glass, but vastly more shatter-resistant. Supplied with a removable protective film (typically on both faces), it’s ready for fabrication and installation in a wide range of indoor and outdoor applications.

Key Features / Specifications

• Model / Part Number: 121818PC
• Product Type: Polycarbonate Window Sheet
• Material: Impact-modified polycarbonate (high-impact grade)
• Finish: Clear / Transparent
• Dimensions: 1/8" × 12" × 18"
• Thickness: 1/8"

Fabrication & Installation Notes

• Cutting: Score-and-snap (thin cuts) or fine-tooth saw blades (carbide recommended)
• Drilling: Use slow speeds; support sheet; step drills recommended
• Fastening: Use neoprene washers or grommets; allow clearance for thermal expansion (~1/16")
• Adhesives: Use polycarbonate-compatible adhesives (silicone, polyurethane); avoid strong solvents
• Forming: Can be thermoformed with proper heat and tooling

Ideal For

• Security glazing and storm panels
• Machine guards and protective shields
• Display windows and sneeze guards
• Protective covers and enclosures
• Projects requiring high impact strength with glass-like clarity
