A fully certified fire rated glazing system reduces supply chain ambiguity, specification misinterpretation or risk of product substitution. As part of the 360-degree Wheel of Assurance, the system is produced in-house by Promat, fitted by a Promat-approved installer and a Certificate of Conformity is issued upon completion for maximum peace of mind. A variety of framing options are available, including steel and timber along calcium silicate which can be concealed in walls and floors to offer a ‘virtually frameless’ solution or over clad to suit any building interior. A range of toughened fire safety glass which provides integrity and heat insulation for 30 to 180 minutes (EI Classfication). The solutions provide 1B1 impact classification offering high performing acoustic properties and UV stability.
Extra protection with Pyroguard fire safety glass
Passive fire protection is a term that encapsulates a range of products that are designed to prevent the spread of fire, protecting a building’s fabric, contents, and – most importantly – save lives. Trudoor is certified by UL to cut, re-certify and label fire-rated glazing materials. Our facility undergoes routine inspections to verify that modifications are done in compliance with the requirements of the UL specification listings.
INTRODUCTION TO FIRE RATED GLAZING
As a key component of building safety regulations, fire-rated glass is commonly used in fire doors, internal partitions, and other structures to enhance fire protection. Fire-resistant glass is specialist glass that has been proven to provide a period protection against fire during a Fire Resistance Test. The degree of protection offered depends on the type of fire rated glass used but generally speaking, all fire-rated glass acts as a barrier to help prevent the spread of flames and smoke in the event of a fire. Certain types of fire-rated glass will also provide a degree of protection (insulation) against the heat of a fire. The ability of glass to prevent the spread of fire throughout a building is one of its most important features. The use of fire-rated glass is therefore an important component in building safety and Building Regulations specify where it must be used.
- When integrated into aesthetically appealing steel, aluminium or timber systems, our glazed solutions ensure a high level of protection can be seamlessly integrated into multiple applications to serve the broader architectural vision.
- These products offer a wide range of shielding levels and options meeting NCRP Report #49 and #147, and Federal Specification DD-G-451, and ASTM C1036Type 1 Class C, Q3.
- Fire safety glass doesn't necessarily mean unsightly fixtures around your office.
Fire-Rated Glass Solutions
Technology has progressed rapidly in recent years in terms of the ability of glazing to stand up to fire for extended periods of time. Low emissivity or solar control layers help fulfil stipulated energy performance criteria, as in Part L of the Building Regulations. Installation of fire rated glazing must always be carried out by a competent person with relevant specialist knowledge, and the glazed system must be fitted into a frame with the appropriate test evidence. In the following blog, we take a look at how fire resistant glass actually protects against fire, first exploring its unique construction and subsequently detailing its various ratings.
If panes are of a thickness greater than 6mm, with a width less than 250mm and area less than 0.5m2, an impact-rated glass is not required. Comparative testing of E and EW glass demonstrates how quickly radiant heat can cause items on the unexposed side to start smoking and then ignite. EW glass provides greater time for people to escape safely and for the fire brigade to access the area.
For that reason, fire-protective glass is most commonly specified for use within opening-protective assemblies, 1-hour walls and door vision panels. Other permitted applications for fire-protective glass include doors and openings of less than 100 square inches in size. The results of these standardized tests—expressed in time—enable architects and designers to choose glass products that will meet code for specific applications.
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. The integrity rating of fire rated glazing is the amount of time the glass will remain in situ in its frame/fixings under the effects of fire. This also denotes the glass's ability to prevent the passage of flames and hot gasses through the glass when exposed to fire on one side.
We have a range of different designs available and are happy to discuss these options with you during a consultation. It almost goes without saying, but fire rated glass will save lives in the event of a fire. It will add precious minutes to allow occupants to evacuate, and help to protect a home or business by giving the fire service extra time to put out the flames.
One of my glass panels was chipped, I contacted one of the team and it was re-made and delivered within 1.5 days. All internal notches will have a 7mm radius to ensure structural integrity during the toughening process.
The glass is classified by the time it provides fire integrity (E) and insulation (I). Integrity refers to how long the glass remains intact in its frame, preventing the passage of flames and hot gases, while insulation measures how well the glass limits the heat passing through to the non-fire side. Fire-rated glass is specially engineered to stay intact during a fire, preventing the spread of flames and smoke. Our 7.2mm Pyroguard provides a 30-minute integrity rating, meaning it can withstand intense heat for half an hour. This critical feature buys valuable time for building occupants to evacuate and for firefighting teams to respond.
The small black edge around each opening door is the only profile that you will see, which creates a neat finish to the edge of the door; this back-painted area hides the intumescent seal of the fire rated glass. When looking fire rated glazing at a fire rated glazing system, both the framing and the glass much be taken into consideration. With fire rated glazing you cannot deviate away from the test evidence and what has been certified. It is imperative that the fire rating classifications are paid strict attention to as this is the test evidence that demonstrates the ability of each system.
