MUBEC applies to all towns within the State of Maine (Maine Uniform Building Code or Maine Uniform Energy Code, see Chapter 1 below). 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. IRC rules require that windows of a certain size or location in your home must have tempered safety glass. You mention the IBC but refer to the IRC, either way I don't think it is required.

Then, the glass is cooled quickly. INTERNATIONAL RESIDENTIAL CODE Page 2 of 2 10. 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 minimum egress window opening is 20" wide. One of these requirements is having the right type of glass in the doors and windows of your home. The proceedure involves heating the glass up, and then cooling it down rapidly. 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. Provisions for design loads of all exterior cladding of residential structures—including fenestration—are set forth in Section R301 of the 2018 IRC. This process makes the glass stronger, and also changes the way the glass breaks. The 2018 International Residential Code (IRC) includes a code requirement for residential glass railing that is similar to the wording in the IBC. 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. Glass type, condition, class, form, quality and finish as defined in ASTM C1036 must meet these standards and the modulus of rupture. Louvered windows and jalousies complying with the requirements of Section 2403.5. The 2018 International Residential Code will include a code requirement for glass railing that is similar to the wording in the IBC. 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. The design loads of concern for vertical glazing are design wind load and impact resistance. 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. A label shall be permitted in lieu of the manufacturer’s designation. Tempered glass, also called safety glass, is created by heating sheets of glass until they are very hot. Tempered Glass in Doors According to the International Residential Code, you must temper all glass and panels in swinging, sliding, operable, fixed, and bifold doors, regardless of the panel’s size. Fire department glass access panels shall be of tempered glass. 3M™ Safety Window Film lets you upgrade your glass to code for a fraction of the cost of replacing the glass. According to the IRC, all glass panels in fixed, sliding, swinging, operable, or bifold doors should have tempered glass or laminated glass installed. 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. Glass design is an allowable method. 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. Any other exterior door has a threshold height limited to 7 ¾ inches. *. Additionally, it is required to temper any glass located within 24″ of a door if … sand blasted, acid etched, ceramic fired, laser etched, or embossed). 6. 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. Glass-block panels complying with Section 2101.2.5. This alone should disqualify tempered glass from being used in any application that requires a fire-resistance rating. The tempering process exposes the glass to high temperatures, which strengthens it to four or five times that of regular glass. The minimum egress window opening height is 24" high. 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). 11. This comprehensive, stand-alone residential code establishes minimum regulations for one- and two-family dwellings and townhouses using prescriptive provisions. The tempered glass required in dangerous locations is different from the glass usually used in windows. A lot of people will refer to the term “Egress Windows” when in reality the code references “Emergency Escape and Rescue Opening”. The main one you need to understand is when it is required to use Tempered safety glass. 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. Tempered glass is glass that has an extra proceedure done to it to make it 4 to 5 times stronger. 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. Mirrors and other glass panels mounted or hung on a surface that provides a continuous backing support. ofthe stairs per item #11. 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. 7. Scope of Summary The codes are categorized into two broad groups - Residential and Commercial: Residential: • 2003 International Residential Code for One- and Two-Family Dwellings. Building codes may specify that glass near certain hazardous locations, such as wet surfaces, doors, floors, ramps and stairs, meet certain safety glazing requirements. 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. 5. Means of Egress Doors in the IRC. While tempered glass is perfectly safe when properly used, it can pose hidden risks when used in fire-rated applications. The fully tempered glass must have an average Modulus of Rupture Fr ≥ 24,000 psi. 2018 IRC Update 5/22/2019 5 2018 IRC Significant Changes to Deck Provisions 9 GENERAL REQUIREMENTS Permits –R105.2 Item 10 –A permit not required for a deck that meets ALL these requirements: • Not exceeding 200 ft2in area • Not more than 30 inches above grade at any point • Not attached to a dwelling • Not serving the egress door This tempered glass will crumble into small, rounded pieces if it is broken.

IRC 308.4.1 or IBC 2406.4.1. The glass must be Kind FT fully tempered glass conforming to the requirements of ANSI Z97.1-14, ASTM C1048 and CPSC 16 CFR 1201. requirements in this very competitive environment. A factor of safety of 4 is specified by IRC to be used with the glass live loads shown previously. Safety Glazing 5 Impact Test CPSC 16 CFR 1201 First, tempered glass is extremely sensitive to high levels of thermal stress, or uneven heating or cooling. Skylights and sloped glazing are also subject to snow load and dead load. 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. As for a general understanding of these requirements, let us look at the 2015 International Residential Code (IRC) for what the minimum standards are. Safety Glazing Required Locations: 1. The code references listed below can be used as a guideline to determine when safety glazing is required. This rule applies to: Certain windows that are … equal to the fire resistive rating required for the wall assembly. Glazing in railing in-fill panels shall be of an approved safety glazing material that conforms to the provisions of Section … Exposed glass edges shall be smooth. 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). Although egress windows are necessary on the first and second floors, the codes are most strict in terms of basement conversions. Wired glass with wire exposed on longitudinal edges shall not be used in louvered windows or jalousies. 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.
