A Guide to Fire-Rated Doors in Houston

A Guide to Fire-Rated Doors

If you don’t consider the worst possible scenario, you won’t be ready to face it when it comes. By investing the time and money into a fire-rated door, you could save lives and your business’ essential assets in the event of a fire. 
But how do you know when and where you need a fire-rated door? Are there differences between fire-rated overhead doors in Houston? When does the law require you to have a fire-rated door?
Untangling the questions surrounding fire-rated doors for your Houston business can seem daunting. We’re here to explain the ins and outs of garage doors for fires.

What Is a Fire-Rated Door?

When you add a door to a fire-rated wall, you’re creating a weakness in the firewall. Choosing a fire-rated door returns the majority of that stability to the barrier.
A fire-rated garage door is a commercial door that has been UL-listed as resistant to a fire breach for several hours. These doors close in the event of a fire to localize the fire and smoke and prevent it from spreading. Fire-rated doors can resist and slow the spread of fire for a certain amount of time. They consist of coated, galvanized or stainless steel and have a rating that explains how long they will resist fire if installed correctly. The higher the rating, the longer your door will protect against fire entering the room. Garage doors can have ratings between three-quarters of an hour to three hours.
The fire rating you choose for your door should generally match the surrounding walls. The Federal Emergency Management Agency recommends selecting a door rated at least three-quarters of the qualifications of the surrounding wall. For example, a wall certified for one hour of protection should have a door rated for 45 minutes.
They give individuals additional time to escape safely. They can also increase the time that essential documents or company assets stay safe from the fire. That extra hour could mean the difference between your valuables going up in flames and them surviving the fire if it gets extinguished in time. 

Where Are Fire-Rated Garage Doors Used?

A few examples of locations that require effective fire-rated garage door placement include the following.

  • Parking garages: Your clients count on you to keep their vehicles safe. Earn their trust with a garage door that will keep the cars safe from theft and fire.
  • Warehouses: After your employees, keeping your merchandise and product stock safe during the fire is the chief priority. It could mean the difference between financial ruin and the ability to get back to business after the fire. 
  • Distribution centers: Your clients rely on you to continue supplying the products that keep their businesses alive. Without their usual shipments, you could put them in severe financial trouble. If you supply stores across the country, one fire could cause a chain reaction of national business dilemmas. 
  • Mills: Modern grinding mill operations use a lot of heavy-duty, expensive machinery. In the case of a fire, there’s no way to move this gear out of harm’s way. Protect the costly equipment by installing a fire-rated garage door to slow the spread of the fire. You’ll give the fire department time to arrive and put out the fire, saving the equipment. 
You should also consider fire-rated garage doors whenever they divide two buildings or open into a hazardous area. For example, if a garage door opens into a boiler room, having a fire-rated sectional door there could protect against a fatal explosion.
Always read the fire code in your area to make sure you are following local laws.

Do I Need a Fire-Rated Garage Door?

You will want fire-rated doors in your commercial facility for many reasons. For one thing, your local or state commercial building ordinances may require it. If you do not have sufficient fire safety measures in place to keep your business up to code, you risk having your company shut down. Not having fire-rated doors could be the difference between keeping your business operational and failing your inspection.

Do I Need a Fire Rated Door

Your staff and your safety are paramount, but protecting your company’s assets ranks as a top priority as well. Fire can rapidly spread through a business and cause a tremendous amount of damage before local emergency personnel even hear about the incident. Adequately installed fire doors as part of a professional floor design will cut off the fire from the people and valuable property that may be inside the building, allowing everyone to escape safely and protecting your property and inventory from harm until help arrives.

While some managers balk at the idea of laying out money for the expense of a fire door, they pay for themselves — and then some — if you do have a fire.

Benefits of Fire-Rated Garage Doors

Protection against potential fire is the obvious benefit to a fire-rated garage door. It can stop, decrease or slow the spread of a potentially lethal and destructive fire. 
Perhaps more importantly, most fire-rated doors protect against toxic fumes caused by fire. In fires, most civilian deaths result from smoke inhalation, not direct contact with flames. Knowing this fact emphasizes the importance of this feature.
In addition to fire protection, fire-rated doors offer added protection to your business if intruders try to enter your building. Their sturdy nature can act as an impenetrable force, which can protect your wares and sensitive information from theft. 

Fire-Rated Garage Doors FAQ

Before selecting the fire-rated door that works best for you, you might have a variety of questions. Here are the answers to frequently asked questions about fire-rated garage doors.

  • How do fire-rated garage doors work? On our Clopay® doors, the protective sheet metal enclosure known as the hood provides fire-resistance to the door’s head and brackets. Each component works together to keep your equipment, wares and employees safe.
  • How long can a fire-rated garage door last in a fire? Ratings range between 45 minutes to three hours. The rating you need will change based on the firewall rating of the surrounding wall.
