GLAZING INFORMATION

  • Use of structural security framing systems with equal or greater forced entry and/or ballistics ratings as the selected MAKROLON HYGARD laminate is recommended.
  • Size MAKROLON HYGARD laminates to allow for a minimum of 1˝ edge engagement in the frame, with sufficient rabbet depth for material expansion (approx. 1/16˝/ft.).
  • Use wet or dry sealants/gaskets that are compatible with polycarbonate.
  • Remove protective masking after glazing operations are completed and before prolonged exposure to direct sunlight, moisture, or high temperature.

CLEANING INSTRUCTIONS

  • Rinse with clean water to remove abrasive dust and dirt.
  • Wash with soap or mild detergent using a sponge or soft cloth. Do not scrub.
  • Rinse once more. Dry with a soft cloth or chamois to prevent water spots.
  • To remove labels, stickers, or grease, rub gently with a cloth wetted thoroughly in VM&P naptha or isopropyl alcohol. Wash and rinse. Do not use razor blades, scrapers, or squeegees.
