Enhancing Safety And Aesthetics With Fire Rated Glass Doors

Liberty Shielding   •   08 September 2023

Fire rated glass doors have been around for centuries, but it wasn’t until relatively recently that their safety features became widely known. Fire rated glass doors provide an effective way to protect people and property in the event of a fire, as they are able to resist high temperatures and contain the spread of fire and smoke. Here, let’s explore the elegance of fire rated glass doors and how they have improved safety over time.

Understanding Fire Rated Glass Doors

In the past, building regulations often stipulated that heavy metal doors should be used in order to provide a certain level of fire resistance. However, these doors are bulky and unattractive, making them less than ideal for modern buildings. 

Fire rated glass doors provide an elegant alternative that is both aesthetically pleasing and provides superior protection from fire. The use of laminated glass ensures that the door can withstand high temperatures without shattering or cracking, allowing it to effectively contain fires while still remaining lightweight and easy to open in case of emergency evacuations.

Fire rating classifications are determined by the amount of time that it takes for a fire to break through the door. A 20-minute fire rating means that it will take a fire at least 20 minutes to breach the door, while a 90-minute rating will take at least 90 minutes. Fire rated glass doors can typically reach ratings of up to 90 minutes, though this is not always necessary depending on the building’s requirements. For example, a healthcare facility or other critical infrastructure requiring extra protection may need at least a 60-minute rating in order to comply with regulations.

What Are The Advantages Of Fire Rated Glass Doors?

Fire rated glass doors have several advantages over traditional metal or wooden doors. Here are just a few of them:

Enhanced Safety And Security

Fire rated glass doors offer an additional level of protection from fire, smoke, and heat. They also help to keep out burglars and other intruders since they are more difficult to break through than most other types of doors.

Aesthetic Appeal And Design Versatility

These glass doors can be designed with a variety of finishes and styles, letting you customize the look of your building or office space. Additionally, these doors are less bulky than traditional metal or wooden doors, making them a great option for areas where you need to maximize available space.

Natural Light And Visibility

Glass doors let natural light pass through, creating a bright and inviting atmosphere. The fire rated glass also allows you to keep an eye on the activities within a room, without having to open the door. This is especially useful for security or monitoring purposes.

Energy Efficiency And Sustainability

Glass doors are a great option for making your space more energy efficient by reducing the need for additional lighting. With the increased levels of insulation that come with quality glass, you can cut down on heating and cooling costs while still achieving your desired comfort level. Additionally, they are an eco-friendly choice due to their longevity and low maintenance requirements throughout their lifespan.

Compliance With Building Codes

When it comes to making sure you are compliant with building codes and regulations, glass doors provide an added level of safety. Fire-rated glass is code compliant for most commercial buildings, providing a buffer between occupants and the potential danger of fire. It also acts as a barrier that restricts the amount of smoke and toxins circulating within your facility.

Installation And Maintenance Of Fire Rated Glass Doors

Installing fire-rated glass doors is a complex process that requires specialized tools and expertise. Experienced technicians have extensive knowledge and experience installing fire-rated glass doors.

Proper Installation Procedures

During the installation of fire-rated glass doors, professional technicians ensure that all necessary steps are taken to provide proper security and safety. These include:

  • Proper Anchoring – For correct operation, fire-rated glass doors must be securely installed in order to remain sealed against smoke and fire. Installers use specialized anchors designed specifically for this purpose.
  • Sealing the Frame – Proper seals are essential to keep smoke and fire from entering through any gaps in the frame. Technicians use high-quality pure silicone, closed cell PVC tape, and fire-resistant sealants to ensure a tight fit.
  • Installing Door Components Correctly – Fire-rated glass doors require specific hardware such as hinges, closers, locks, and strike plates for proper operation. Installers make sure these components are properly installed and aligned.
  • Testing for Air Leakage – Once the door is installed, expert technicians use a specialized instrument to test for any air leakage around the frame. By doing so, we can make sure that the fire-rated door is providing maximum protection from smoke and flames. 

Maintenance Tips And Best Practices

To keep your fire-rated door functioning properly, it’s important to follow these simple tips and best practices: 

  • Regularly inspect the door for any damage or loose components.
  • Ensure that gaps around the frame are sealed tightly with high-quality products, such as pure silicone sealants. 
  • Clean the door regularly to prevent dirt from accumulating and causing problems with the functionality of the door.
  • Pay attention to any signs of corrosion or rusting on metal components, as this is a sure sign that something needs to be addressed. 
  • Have your fire-rated door inspected by a qualified technician at least once per year.
