Ray-Bar has successfully engineered, designed, tested, manufactured, fabricated, and supplied code compliant Life and Safety specialty glazing products and assemblies for over 80+ years. We are a global manufacturer, having worked on a national and international scale for literally thousands of projects and facilities worldwide. Class EW (Integrity & Radiation) rating is also a measure of Integrity performance (E) with the addition of the ability to minimize radiant heat transfer from the fire side to the unexposed side. By reducing the amount of energy passing through its surface, EW-classified fire-resistant glass can provide enhanced protection against the spread of fire and create safer evacuation passages.
- These materials hold up in temperatures above 1500 °F, making for a highly reliable fire barrier that can prevent the spread of flames, fire, smoke, and extreme radiant and conductive heat.
- This also makes it easier for firefighters to tackle the fire when they arrive at the scene, reducing the risk of injuries and fatalities while also limiting the amount of fire, smoke, and water damage to the rest of the building.
- Some fire-rated glass intumescent layers turn opaque in the heat of a fire which stops vision through the glass – this can help to reduce the level of panic when leaving the building.
- Insulation (Measured in Minutes) defines the resistance to the passage of heat through the glass.
A place of greater safety
The cooling, impact and erosion created by the hose stream tests the integrity of the glass. In the U.S., the hose stream test is required for all fire ratings over 45 minutes (all fire ratings require it in Canada). Fire-rated glazing can be used in doors, windows, screens, and walls to provide fire protection without blocking the light or obstructing the view between sides. The range of products we offer includes not just Pyroguard, but also the more advanced Pyrobel and Pyrobelite, which can provide insulation to prevent heat transfer from one side to the other, depending on the thickness. Can be double glazed using 15mm fire-rated glass and 12.8mm acoustic laminated glass. For this glass type to serve its primary function, it must be correctly specified, placed and installed following building regulations.
FRAMING OPTIONS
In 2003, Wired glazing was forced to comply with CPSC impact-safety standards. In 2006, wired glass was banned, though can still be made available with surface applied safety film in limited applications. In the event of fire, we face threats like hot gases, smoke and heat transmission. Our glass solutions are able to resist such threats and suit the requirements of a complete range of building applications – including aesthetically appealing system solutions for seamless architectural integration. Integrity is the length of time that the glass remains in its frame and successfully blocks the flames and smoke. It is the level of fire protection provided by the glass and it is typically measured in periods of time, upwards of 30 minutes.
toughened glass
In the event of a fire, the interlayer reacts to the heat and expands and reacts creating an effective safety barrier from the radiant heat of a fire. Yes, our products are independently tested to BS and EN standards and installed by our 3rd-party accredited project delivery teams. We prioritise safety and ensure our products meet or exceed all necessary standards. It appears to be just a transparent and ordinary pane of glass – however, if a fire was to start, its presence can quickly become a matter of life or death. This specialist construction material offers effective resistance in the face of flames, heat and smoke and it has an incredibly important role to play with respect to building fire safety.
Low g-values (solar energy transmittance of glass, also called a solar factor) can be achieved. U-values (efficiency of an insulating material) can be as low as 1.0W/m2 for double-glazed units or 0.6 W/m2 for triple-glazed units (centre pane value). All manufacturers should test their glass in accordance with this standard, to comply with UK regulations and the European requirement for CE marking. They have a fire property or function which does not warn of, or extinguish, fire.
Using fire-protective and fire-resistive glazing will help to slow or stop the spread of fire, by making glass panels more resistant to flames, smoke and heat. 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. In summary, fire-protective glass is tested to measure its ability to prevent the spread of fire and smoke during its prescribed rating period. Fire-resistive glass performs the same function, yet also restricts the spread of radiant heat to protect occupants and prevents combustion. To achieve code compliance, framing elements must match the prescribed level of fire rating for the glass and glazing.
For instance, genuine Pyroguard Fire Glass is typically marked with the brand name, the standard (like EN14449), and the impact rating (e.g. 2B2). Additionally, a genuine Pyroguard stamp indicates certification for specific fire-rated applications. Understanding the nuances of fire-rated glass is crucial, not just for compliance, but also for ensuring safety in both domestic and commercial settings. In this article, the Bridgewater Glass team (with over 75 years’ experience in the bespoke glass game) explains everything you need to know about fire-rated glass, including what it is and how to identify it. Using a low-emissivity or solar-control counterpane can help to meet a specified energy performance criteria, as set out in Part L of the Building Regulations.
Based on the fire rated glass cut to size amount of time the glass remained fixed in place, it is assigned a 20-, 45- or 60- minute (or longer) fire rating. The rate by which temperatures increase during these tests also is regulated to simulate stages of an actual fire. Leveraging our efficient in-house production and volume purchasing, we’re able to extend the most competitive prices for fire rated glass, without ever compromising on the quality or safety standards you trust. We stand out in the market with our fast shipping commitment, aiming to ship most orders within just 1-2 days. Rely on our expertise for fire rated glass that not only meets your needs but is delivered swiftly and with the best value possible. Glass and Glazing Federation (GGF)The Glass and Glazing Federation (GFF) represents companies that manufacture, supply or install glass and glazing products.
But what else separates fire rated glass from its cheaper, but less safe, cousins? BS EN sets out the impact safety requirements for glass in buildings, with a pendulum impact test method used to classify glass products into three principal classes. For example, depending on the height of the building, the depth of the basement, and the presence of sprinklers, fire resistance of up to 180 minutes may be required for buildings other than dwelling houses. Fire rated glass is classified by the amount of time it provides for integrity and insulation, and is broken down into numbers for UK building regulations.
Offering double-sided fire resistance, its large sheet size can be cut to size, making it a cost-effective solution – suitable for both steel and timber applications. When structural glazing is installed with glass to glass joints, a thermoplastic spacer (TPS) is introduced down the edge of the glass, which is silicone. This means that where there is a glass to glass joint, there will be a nominal 26-32mm black silicone join running the height of the frameless fire glass. With over 130 years of experience, SCHOTT is a leading international technology group in the areas of specialty glass, glass-ceramics, and related high-tech materials. SCHOTT AG has its headquarters in Mainz (Germany) and is solely owned by the Carl Zeiss Foundation.

We thank our clients, our team, and our partners for four decades of growth, and look forward to many more. We offer customized support to fit your needs, and dedicated staff with over three decades of fire-rated glazing and interlayer/ lamination experience. Orders delivered by Fragilistics do not require packaging as specialist glass delivery vehicles are used.
This allows for a comfortable time to escape a building in the event of a fire. 30 minute fire rated glass systems still remain minimal and as frameless as possible despite their high performance against fire and extreme heat. They are suitable for various applications, including commercial buildings, airports, hospitals, schools, and residential buildings.
