Safety Glass General Information

General information of safety glass includes requirements and certificate of the glass.


What is Safety Glass?
Safety glass is glass with additional safety features that make it less likely to break, or less likely to pose a threat when broken. Common designs include toughened glass (also known as tempered glass) and laminated glass.

The Safety Glazing Certification Council (SGCC®) is a non-profit corporation, established in 1971 by manufacturers of safety glazing products, building code officials, and others concerned with public safety. SGCC® maintains a program which provides for the certification of safety glazing materials found to be in compliance with one or both of the following specifications.

The following shall be considered specific hazardous locations requiring safety glazing materials:
  1. Glass in any door
  2. Glass in any kind of shower, bathtub area, hot tub, steam room, sauna or whirlpool area where the bottom edge of the glass is less than 60 in. above a standing surface and drain outlet.
  3. Glass in fixed or operable panels adjacent to a door where the nearest exposed edge of the glazing is within a 24 in. arc of either vertical edge of the door in a closed position and where the bottom edge of the glazing is less than 60 in. above a walking surface.
  4. Glass in fixed or operable panels that meets all of the following conditions: 
    1.  Bottom edge is less than 18 in. above floor
    2. Top edge is greater than 36 in. above floor
    3. Total area of glass is greater than 9 sq. ft. (1,296 sq. in.)
    4. One or more walking surfaces within 36 in. horizontally of the glazing
  5. Glass in walls used as a barrier for indoor or outdoor swimming pools or spas when both of the following exist: 
    1. The bottom edge of the glazing is less than 60 in. above a pool side of the glazing
    2. The glazing is within 5 ft. of a swimming pool or spa deck area
  6. Glass in walls enclosing stairway landings or within 5 ft. of the bottom and top of stairways where the bottom edge of the glass is less than 60 in. above a walking surface.

The above mentioned hazardous locations have been evaluated in regards to preventing “Human Impact” and as such, require safety glazing. Safety glazing has been deemed to be glass that is in compliance with standardized testing protocols under ANSI-Z97.1 and SGCC 16 CFR 1201 Cat. I and Cat. II.

PLEASE NOTE: “Human Impact” is not to be confused with Hurricane Impact. Hurricane Impact is tested under ASTM E 1886 and E 1996 protocols and not ANSI or SGCC.

INTUS Windows has passed the required test for the following products:
  1. 4 mm (5 /32 in.), tempered glass pane
  2. 6 mm (1 /4 in.), tempered glass pane
  3. 33.2 (1 /4 in.), laminated glass pane 
*According to SGCC, “When a laminated glass is certified, other laminated glasses having a greater thickness of interlayer will be included in the certification.” Therefore, any glass configuration that has two or more polyvinyl butyral (PVB) films and is greater than 6 mm (1 /4 in. all combined) is considered to be safety glass.
