MAKROLON 15® Polycarbonate Sheets

The first glazing replacement option with a 15 year performance warranty. MAKROLON® 15 Polycarbonate Sheet offers superior weatherability.

This New Superior Polycarbonate Sheet Glazing Solution Offers:


  • Long−Term Weatherability
  • Vastly Improved Glazing Durability
  • Optical Clarity
  • Vandalism Protection
  • Substantially Superior Impact Resistance
  • Significant Weight Reduction
  • Enhanced Insulating Properties


MAKROLON® 15 Polycarbonate Sheet offers long-term weatherability and is backed by a 15 year performance warranty. This significant performance enhancement is derived from MAKSHIELD™ innovative coating technology. MAKROLON 15 Polycarbonate Sheet achievement in performance offers significant longevity in the application life cycle costs.

MAKSHIELD hard-coat surface approaches the hardness of glass and addresses the issues previously associated with polycarbonate sheets*.

MAKSHIELD coating technology, combined with the impact strength of MAKROLON Polycarbonate Sheet, builds on Sheffield Plastics’ long history of "none tougher" polycarbonate products.

MAKROLON 15 Polycarbonate Sheet is clearly the right choice for glazing where there is potential for glass breakage. These applications include schools, public buildings, transportation centers, and in areas where high traffic and vandalism is prevalent.

*Note: Based on ASTM Taber Abrasion Test D1044-99, 100 cycles.
