This tempered glass will crumble into small, rounded pieces if it is broken. The egress window must have a glass area of not less than 8% of the total floor area of room (s) for which it is servicing, to allow the minimum amount of sufficient natural light. This factor of safety is used with the modulus of rupture of tempered glass which is taken to be 24 ksi → allowable stress for live loads = 6 ksi (41.4 MPa). The design loads of concern for vertical glazing are design wind load and impact resistance. INTERNATIONAL RESIDENTIAL CODE Page 2 of 2 10. Safety Glazing Required Locations: 1. Although egress windows are necessary on the first and second floors, the codes are most strict in terms of basement conversions. The proceedure involves heating the glass up, and then cooling it down rapidly. Glass design is an allowable method. windows and doors installed when the house was built) may need to be replaced with tempered glass when building an addition, porch or deck onto an existing house. This process makes the glass stronger, and also changes the way the glass breaks. The code references listed below can be used as a guideline to determine when safety glazing is required.

Any other exterior door has a threshold height limited to 7 ¾ inches. 2018 IRC Section R311.3.1 restricts threshold height a required exit door in residences to 1 ½ inches from the top of the the threshold to the floor or landing on each side of the door. As for a general understanding of these requirements, let us look at the 2015 International Residential Code (IRC) for what the minimum standards are. 5. Exposed glass edges shall be smooth. An egress window is a window defined by local building codes as large enough for entry and exit of a room in an emergency. 5. Means of Egress Doors in the IRC. Then, the glass is cooled quickly. While tempered glass is perfectly safe when properly used, it can pose hidden risks when used in fire-rated applications. Glass-block panels complying with Section 2101.2.5. One of these requirements is having the right type of glass in the doors and windows of your home. requirements in this very competitive environment. Skylights and sloped glazing are also subject to snow load and dead load.

The minimum egress window opening is 20" wide. sand blasted, acid etched, ceramic fired, laser etched, or embossed). W. 18" from the window per exception #9, , I "d" 'dtb In ow IS not require 0 e tempered where the stairs are provided with a handrail or guardrail and is greater than The 2018 International Residential Code will include a code requirement for glass railing that is similar to the wording in the IBC. 2018 International Building Code (2406.4.3) specifies that tempered (safety) glass is needed if all these conditions exist: The exposed area of an individual pane is greater than 9 square feet (0.84 m2). It is important to note that the required opening size of 24 inches high, 20 inches wide and 5.0 or 5.7 square feet in area must be met by “normal” operation of the window, door or skylight without the use of keys, tools or special knowledge, and without the removal of a second sash from the opening. The tempering process effectively eliminates the shards and reduces the chance for injury when a window breaks. Any glass that is within 24 inches of a doorway must be made of tempered glass if the bottom edge of the glass is 60 inches or less above the walking surface. The thickness and type of glass that is installed in the window a. annealed glass b. tempered glass c. laminated glass d. insulated glass e. insulated laminated glass Section G – Opening Protection Mitigation Techniques Resource Document The International Residential Code is designed to meet these needs through model code regulations that safeguard the public health and safety in all communities, large and small. A factor of safety of 4 is specified by IRC to be used with the glass live loads shown previously. *. The fully tempered glass must have an average Modulus of Rupture Fr ≥ 24,000 psi. The revised model code (Section 2407.1) now states, “handrail, guardrail, or a guard section shall be laminated glass constructed of fully tempered or heat strengthened glass and shall comply with Category II or CPSC 16 CFR Part 1201 or Class A of ANSI Z97.1. ofthe stairs per item #11. MUBEC applies to all towns within the State of Maine (Maine Uniform Building Code or Maine Uniform Energy Code, see Chapter 1 below).

Float, wired and patterned glass in louvered windows and jalousies shall be not thinner than nominal 3 / 16 inch (4.8 mm) and not longer than 48 inches (1219 mm). Tempered glass, also called safety glass, is created by heating sheets of glass until they are very hot. International Code Council 2003. Wired glass with wire exposed on longitudinal edges shall not be used in louvered windows or jalousies. Code Change Removes Sprinkler Tradeoff for Doors in Exit Enclosures and Passageways To repeat, nearly all of the modifications to Tables 716.3, 716.5 and 716.6 in the 2012 IBC are intended to clarify requirements and limitations on FRG in effect since the 2006 IBC. Louvered windows and jalousies complying with the requirements of Section 2403.5. Glass doors. First, tempered glass is extremely sensitive to high levels of thermal stress, or uneven heating or cooling. The glazing would need to be in the panel of the door, or if adjacent to the door (above or beside) then below 60" to be considered hazardous. This comprehensive, stand-alone residential code establishes minimum regulations for one- and two-family dwellings and townhouses using prescriptive provisions. 11. Fire department glass access panels shall be of tempered glass. Glazing adjacent to stairways, landings and ramps within 36 inches (914 mm) horizontally of a walking surface; when the exposed surface of the glass is less than 60 inches (1524 mm) above the plane of the adjacent walking surface. Glazing in nearby existing windows and doors (i.e. Last month, my ICC chapter had a 6 hour course on inspecting a house by the IRC and the instructor (an ICC certified 30 year building inspecter from Minnesota) took pains to explain to the class that the requirement for “safety glass” was not filled by tempered glass or wired glass. = 4 (assumed to be Where safety glazing is required, each pane must be provided with a manufacturer’s label defining the type of glass and safety glazing standard to which it complies. Additionally, it is required to temper any glass located within 24″ of a door if … Building codes may specify that glass near certain hazardous locations, such as wet surfaces, doors, floors, ramps and stairs, meet certain safety glazing requirements. Where required, tempered glazing (except tempered spandrel glass) shall be permanently identified by a manufacturer marking that is permanently applied and cannot be removed without being destroyed (e.g. Allowable glass stress F.S. This alone should disqualify tempered glass from being used in any application that requires a fire-resistance rating. A lot of people will refer to the term “Egress Windows” when in reality the code references “Emergency Escape and Rescue Opening”. • 2006 International Residential Code for One- and Two-Family Dwellings. the test requirements Exceptions: Mirrors and other glass panels mounted or hung on a surface that provides a continuous backing support Glass unit masonry IRC: Louvered windows and jalousies IBC: Plastic glazing shall meet the weathering requirements of ANSI Z97.1. Safety Glazing 5 Impact Test CPSC 16 CFR 1201 The label must be permanently etched, fired, or embossed, on the glass or be a type that once applied cannot be removed without being destroyed. Exception: An attached top rail or handrail is not required where the glass baluster panels are laminated glass with two or more glass plies of equal thickness and of the same glass type. Glass type, condition, class, form, quality and finish as defined in ASTM C1036 must meet these standards and the modulus of rupture. equal to the fire resistive rating required for the wall assembly.
