IBC requires that fire-protective and fire-resistive glass be labeled to indicate their designated levels of protection. It is important for specifiers of fire-rated glass to know how to interpret the labeling so the products they specify for a specific application meet all related codes in a particular jurisdiction. As a result of their potential for transmitting radiant heat, glasses rated as fire-protective cannot exceed 25% of the total area of a wall.
Fire Rated Glazing
It can be used as a Vision Panel or Privacy Panel, side panel or even as a Glazed Partitions. Fire rated glass can also come with acoustic ratings (see Acoustic Glass) that can be vital for certain building projects.We stock a comprehensive range of fire-rated glass products and to see the Features tab for more information. Fire-rated glazing can be used in doors, windows, screens, and walls fire rated glass cut to size to provide fire protection without blocking the light or obstructing the view between sides. Available in both single and double door options, Technishield 70 offers 90/90 minutes integrity and insulation. Like integrity glass, this classification of glass stops both flames and hot gases from penetrating through to the other side.
- Recent studies suggest that some non-compliant or fraudulent fire rated glazing materials may be on the market, which can have potentially hazardous implications for life safety.
- The glass must be tested and classified in its proposed end use application, for example as a sky room, sky frame, glass wall, or glass floor or any other glazed system.
- Fire-rated glass plays a vital role in enhancing building safety by providing transparent barriers that resist the spread of fire and smoke.
- However, in reality, it provides only a guideline and is open to interpretation in many areas.
- Because fire rated glass is used in door and wall assemblies, code requirements for framing must also be considered.
Product Modeling
Emirates Glass has partnered with the international technology group SCHOTT to provide architects in the Middle East and beyond with high-performance glazing that combines fire-resistance and design freedom in a unique way. With fire protection there can never be any doubt or compromise about standards or product performance. Promat fire rated glass and glazing systems provide proven and assured levels of fire protection and, backed by a wealth of testing and third-party certification that complies with or exceeds UK and European standards. CERTIFIRE assures performance, quality, reliability and traceability of fire protection products. Recognised by regulatory authorities worldwide, it is an internationally respected mark of fire safety and one of the most authoritative in the industry.
Fire Resistive Glass Products from Pilkington Pyrostop®
These different types of fire-rated glass find diverse applications in buildings, prioritizing fire safety while allowing visibility and natural light transmission. A range of cuttable fire safety glass which provides integrity and heat insulation for 30 and 60 minutes (EI Classification). This stockable product provides application flexibility into timber, steel and aluminium framing systems and 1B1 impact performance at short lead times.
Fire-protective glass commonly includes special tempered glass, as well as ceramics and hollow metal framing. Although such glazings are engineered to protect against the spread of flames and smoke—and to achieve fire ratings that range from 20 to 180 minutes—they are still restricted by code to specific applications. The main restricting factor for fire-protective glass is that it is not designed to prevent transmission of radiant heat. PYRANOVA® is a clear, laminated composite glass that offers outstanding levels of fire resistance thanks to a combination of thin glass panes and internal layers.
Following a strict time/temperature curve, the heat in the furnace is raised to an intense level, simulating conditions in a burning building. In order to successfully pass the test, the frame, sash if applicable and glass must remain intact for the duration of the test. Cracking is allowed, provided the glass can still act as a barrier to flames and smoke. Likewise, in scenarios where fire-resistive glass is specified, the framing also must block the radiation of heat for the rated time period. To achieve the required levels of fire-resistance, framing material is typically coated with glazing or insulation that meets appropriate code and testing requirements. A range of fire safety glass certified for butt joint applications, providing integrity and heat insulation for 30 and 60 minutes (EI Classification).
Fire rated glazing can either be defined as fire-protective or fire-resistive. The lesser Fire Protective glazing defends against smoke and Flames whereas Fire Resistive glazing is more advanced in design and restricts the dangerous transmission of radiant heat. These components must be certified to ensure they can withstand the extreme conditions of a fire. Using non-rated hardware can compromise the fire performance of the door, reducing its ability to contain fire and smoke.
Pyrostop is a multi-layer laminated glass product composed of Optiwhite low iron glass, and intumescent interlayers. It is listed for use in doors, sidelites, transoms, borrowed lites and wall applications. The next number measures the heat resistance or insulation of the glass i.e. the amount of time the glass will act as an effective barrier against flames, heat and smoke under the effects of fire.
It is important to know the difference in determining whether an installation complies with codes. Each category has its own set of performance features, test standards and allowed applications. Simply relying on the fire endurance rating (20, 45, 60, 90, 120 and 180 minutes) or whether a product is “thick” or “thin” can lead to faulty specifications and misapplications of the product.
Fire rated glazing can provide higher passive fire protection and may even reduce the need for further fireproofing measures. As always, consulting with a certified fire safety expert in evaluating fire resistance needs when designing a commercial building is essential. Through fire rated glazing, building occupants can feel secure that they are receiving necessary protection from the dangers of fire. Tempered glass is heat-treated for increased strength and safety, shattering into small granules instead of sharp shards. However, fire rated glass like our FireLite® offerings is specifically designed to withstand the intense temperatures of a fire, providing vital fire protection and safety that goes beyond what tempered glass can offer.
