Product Specifications

Advantages of KeepSafe Maximum:

• Hurricane Protection: Windows and doors made with KeepSafe Maximum glass meet or exceed the toughest code requirements for hurricane protection.
• Safety: Resists penetration from accidental impact. If broken, glass fragments tend to adhere to the interlayer thereby reducing the danger of serious injury. Meets CPSC, CFR 1201 and ANSI Z97.1 safety glazing standards.
• Sound Control: Is effective in controlling the transmission of sound into your home.
• UV Protection: Screens out 99% (up to 380 nanometers) of the sun's most damaging rays reducing glare, fading of carpets, drapery, and furnishings.
• Security: Protects against forced entry and resists repeated blows from hammers, bricks or similar weapons. Meets ASTM F-1223 (Class 1) forced entry standard.
• Durability: With glass on both sides, windows are less likely to scratch during routine cleaning or handling. Tends not to bubble, discolor or lose its physical or mechanical properties after installation.
• Appearance: No unsightly metal shutter systems over every window. No stacks of plywood in the yard or garage.

Technical Data: Applicable Standards American Standard of Testing Materials (ASTM)

ASTM F 588-85 Grade 10 - measures a window assembly's resistance to "opportunistic or unskilled burglars."

• Resistance to: hand manipulation, tool manipulation and static load/locking device strength resistance.

ASTM F 588-85 Appendix X2 - requires resistance to:

• A steel-weight pendulum delivering horizontal impacts u to 100 J with an impact diameter of about 1¼".
• Five glazing impacts in a classic domino pattern.

ASTM F 842 Grade 10 - requires sliding glass doors to be resistant to forced entry with no penetration of impactor.

Storm Door Standard

• SPPS E - 079901 - requires resistance to forced entry of storm door assemblies.

The Miami-Dade protocol in the Florida Building Code

• SFBC (Dade County) - most stringent hurricane code in the world, requiring that windows and doors be able to withstand hurricane winds up to 150 miles per hour and impact from windborne debris propelled by such intense forces.

American National Standards Institute (ANSI)

• ANSI Z97.1 - Standard for glazing materials used in buildings - safety performance specification and methods of test.

Consumer Products Safety Commission (CPSC)

• CPSC 16 CFR 1201.

Underwriters Laboratories, Inc., (UL)

• UL 972 - Burglary Resistant Glazing.

Environmental Considerations: Use of laminated glass can reduce heating and cooling costs. Sound attenuation applications mean reductions in noise pollution.
