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.
