What's the difference between a prefab/zero clearance fireplace and a masonry fireplace?

How do I know what kind of fireplace I have? Why is this important?
Prefab Zero Clearance Factory Built Fireplace


(Also know as 'Zero Clearance' or 'Factory Built'. Inside of fireplace is made of sheet metal)
Masonry Fireplace


(Inside of fireplace was made by actual mason using real brick or stone)

It is important to get the right door for your fireplace for installation & safety reasons.

Because prefab fireplaces are made out of metal they have different ventilation requirements than do masonry fireplaces that are made out of brick. For more information, see National Safety Code 123.

Prefab/zero clearance fireplaces are what builders install in many neighborhood homes. They are typically made in a factory out of sheet metal and are essentially a firebox enclosed in a steel cabinet. There is sometimes a metal plate in the upper corner of the insert with a manufacturer name & model number. Some popular manufacturers include FMI, Heat & Glo, Heatilator, Lennox, Majestic, Marco, Martin, Preway, Superior, and Temco.

Since these inserts are all different sizes and the doors fit just inside the firebox opening, it’s helpful if you can find out the manufacturer and model number of your fireplace as well as the measurements, (length and height), of your firebox opening. Our fireplace door consultants can help you with this process.

Masonry fireplaces have a brick or stone firebox, chimney, and surround.

Differences Between Prefab/Zero Clearance Fireplace Doors & Masonry Fireplace Doors

Lexington Fireplace Door in home
Before you start shopping, there are a couple of significant differences between prefab fireplaces and masonry fireplaces that you ought to be aware of. Prefabricated fireplace doors come in hundreds of different sizes. This means there is a good chance you will have to have a door custom made for your fireplace. (FYI, this is why big box stores like Home Depot, Lowe’s, and Menards do not sell prefab doors) Masonry fireplace doors usually come in small, medium and large which make them a much easier purchase.

Prefab Fit

Prefab fireplace doors require a precise fit so there is proper ventilation to meet national safety codes. Lower end masonry fireplace doors have a wide frame and utilize an overlap fit, which means you cover up your fireplace surround, but have a lot of wiggle room for the installation. But don’t worry, buying and installing a replacement door for your prefab fireplace is an easy do-it-yourself project. (Tape measure, screwdriver, & drill).

Helpful Tips When Choosing Your Fireplace Doors

Energy Icon


Fireplace doors cover the opening of the firebox when a fire is not burning and can help eliminate drafts and cold air coming down the chimney into your home. The Hearth, Patio, and Barbeque Association recommends that all fireplaces be provided with glass doors especially if you burn real wood. Fireplace doors are helpful in reducing air leakage up the chimney, eliminating hearth odors when the fireplace is not in use, and stopping smoke spillage into your room.

Beauty Icon


Fireplace doors are not only functional keeping the cold air out of your home and the warmth in, they add a finished, decorative touch to your fireplace. After burning a fire, the firebox may have unsightly stained walls, piles of ashes, or soot stained gas logs. Our bronze or gray tinted glass covers the firebox and makes it easy to hide the remnants of a fire. You can choose from a variety of painted and anodized aluminum or steel frames from standard black to bronze, pewter, and brass with clear or tinted glass.

Help Icon


The most frequently asked question regarding fireplace doors is “Can I burn my fire with the doors closed?” The answer is NO. Your glass could shatter. Also, leaving the doors open ensures the fire has enough air to burn effectively.

Parts of the Fireplace Door

Buckhead Masonry Fireplace Door

Spark Guard

Spark Guards come in the form of mesh doors or mesh curtains and are typically mounted behind the door. Spark guards help prevent sparks from popping out of the firebox while a fire is burning.

Glass Panels

Fireplace door glass panels are made with tempered safety glass to prevent injury. Some doors offer tinted glass options to help conceal leftover ash and soot in the firebox.


Doors typically come in three different styles: bifold, bifold trackless, and cabinet.

Door Frame

The frame is what you insert into (inside fit) or overlapping on top of (overlap fit) your firebox opening. Frames come in many different styles and finishes. The actual doors themselves clip into the frame.

Things To Consider




  • Strong and durable
  • No sway or movement
  • Powder coat finish
The Merino Fireplace Door


  • Economical
  • No rusting
  • Anodized Finish




Mesh curtains are the most affordable spark guard option. Most of the fireplace doors on our website come with the option to add a mesh curtain or even have them arrive pre-installed. While sturdy, hanging mesh curtains aren’t secured at the bottom of your fireplace and may not prevent logs from rolling out of your firebox if you’re burning real wood.

Fireplace Mesh Doors


Mesh doors are built into the frame of your fireplace door. If you burn real wood, mesh doors are the best option for preventing logs from rolling out of your firebox. Unlike fireplace doors, mesh doors can be kept closed while a fire is burning. Since vent-free fireplaces reach very high temperatures, they can often discolor fireplace doors, even if they are open. If you have a ventless fireplace, we recommend using mesh doors in place of fireplace doors.


Mesh screens are placed in front of the firebox on the hearth, and can be used with any fireplace. While they take up more space in front of the fireplace, they also provide more clearance to protect pets and small children. Fireplace screens come in a variety of styles and often feature artistic paneling/metalwork that make for a good decorative piece. Fireplace screens are not secured to anything and therefore may topple over with enough force.

Brick-Anew Fireplace Door Glass Colors

Many of our fireplace doors come in a tinted glass option. Tinted glass helps to hide your firebox after a fire. Tinted glass is a great way to make leftover ashes less noticeable.


If you burn real wood, tinted glass is a great choice to hide the ashes and soot after a fire. If you have a beautiful set of gas logs, clear glass shows them off when they aren’t burning. Got a personal preference? Go with that! It’s totally up to you.

If you have small children or pets, glass doors provide a barrier to the firebox when the fireplace is not in use. Purchasing safety locks for the doors is an extra precaution.

The #1 Myth About Fireplace Doors...

Can I burn a fire with the doors closed?

The answer is no!

And a better question is… Why would you want to? If you burned a fire with the doors closed, most of the heat would go straight up the chimney. Fireplace doors were designed to keep cold air from coming down the chimney into the house. Before fireplace doors were available, a homeowner would have to wait until the fire went out and the flue was closed before going to bed at night. Otherwise, the house would be icy cold the next morning. Closing the fireplace doors when the fire is close to dying out not only keeps sparks from popping out of the firebox but helps keep the cold air out and the warm air in your room. Many people want the ambiance of a fire burning behind closed glass doors, but your doors are not designed to be used in that way. The tempered glass cannot withstand the heat of a full fire, moisture can build up in the tracks and the glass can shatter into your room if the heat gets too intense. Always burn your fire with the doors open.



You may be asking, “If I’m not supposed to burn a fire with the doors closed, why have I seen so many pictures of it online?” The reason why is because fireplace door manufacturers photoshop fake fires behind the doors to make them more visually appealing. At Brick-Anew we recognize that these images can be confusing to customers and do our best to avoid using them whenever possible.

Ready to order?

Here’s what to do next:

Locate your fireplace model number & manufacturer.

If you have a Prefab fireplace, locate your model number & manufacturer. Prefab fireplaces will typically have a metal plate on the front, or just inside the firebox, sometimes it will be inside above the opening. This plate tells you which brand you fireplace is, as well as the specific model number. Having this information on your order makes the confirmation process more efficient.

How To Find Fireplace Model Number and Manufacturer


Take your measurement photos.

Once you’ve identified the manufacturer and model number, take some pictures of the height, width, and recess depth of your fireplace. See below for more info on how to take proper measurement photos. If you are unable to locate your model and manufacturer, review the pictures below, send those photos to sales@brick-anew.com. For more detailed information about how to take proper measurements of your fireplace, read our measurement guide here.
