Prefab Doors

All About Manufactured Fireplaces and Fireplace Doors

This corner fireplace door adds a touch of sophistication to your modern home!

Masonry fireplace doors are one thing, but if you have a factory-built fireplace you need a zero-clearance fireplace door! Pre-fab fireplace doors are specifically made for factory-built fireplaces and a masonry fireplace door simply won’t work on these manufactured fireplaces. (You may note that a few of the fireplace doors we have for sale are compatible with both. It’s best to know what kind of fireplace you have rather than looking only at these universal fireplace doors.)

All our pre-fab doors are after-market fireplace doors. These doors fit most of the factory-built fireboxes on the market, so you can be sure that our glass fireplace doors will work on your fireplace. They are designed with enough air space to keep your zero clearance firebox safe to use. Closing off these gaps can cause overheating of the firebox and potentially start a fire. Check out our learning center article on measuring for a pre-fab fireplace door!

It is VERY IMPORTANT to have the correct fireplace doors on any type of fireplace so that your home is up to code but most importantly, safe! As we mentioned above, the wrong fireplace door can be a fire hazard and it may allow dangerous fumes to enter the home.

Not sure about your fireplace? Take a look at our handy guide and feel free to ask the experts so that you can learn more about your fireplace and fireplace door! When it comes to buying a fireplace door the proverb “measure twice, cut once” applies. You want to double-check all measurements and details before you finalize your purchase to ensure that you are ordering the right product. And, if it seems like a little too much of a hassle or if you just aren’t sure, you’ll love our Snapshot Quote feature!

Benefits of a Fireplace Door

Many homeowners may question why they even need a fireplace door. After all, you know not to get too close to the fire when it’s crackling in the fireplace. The same cannot be said for pets or kids though, so it’s important to consider the safety of your loved ones when you have a fireplace! There are a lot of benefits to customizing the look of your fireplace with a quality fireplace door and we’ve listed just a few of them below:

  • Energy Efficient. Your fireplace door will help regulate the temperature in your home by preventing cooler air in the summer, (or warmer air in the winter,) from escaping through the fireplace.
  • Odor Control. Get rid of that fireplace smell! Even with a chimney cap, smells can develop from built-up soot and moisture.
  • It Looks Good! Without a zero-clearance fireplace door, your fireplace is just a hole in the wall that takes away from the ambiance of the room instead of adding to it.

The Carolina arch conversion fireplace door is perfect if you want an arched fireplace, but you don’t want to spend $5,000+ for a contractor!

Why do you not offer a mesh curtain with your fireplace doors?

Why can't I use ceramic glass doors on my factory-built fireplace?

  • Using your fireplace with the fireplace doors closed causes overheating. Pre-fab fireboxes tend to be thinner steel and without the airflow that open fireplace doors allow, it can become a fire hazard. Using your fireplace doors improperly can create a dangerous and costly situation for your home.

Which fireplace door is right for my prefabricated fireplace?

  • Let us answer this question with a question: are you sure that you have a manufactured fireplace? An easy way to tell is history; if your fireplace was produced in a factory, it’s a pre-fab fireplace, sometimes referred to as a zero clearance fireplace. If not, you should check out our masonry fireplace doors!

  • Once you know that your fireplace is a manufactured unit, look for the metal stamp, plate, or marking indicating the manufacturer's information (such as Heatilator, Majestic, Superior, Marco, Sears, etc.). You should find the tag with the name of your unit either behind the screen or inside above the refractory panel, either on the left or right side. You will be looking for a black metal tag with stamped names and numbers on it.

Can you replace the glass doors on a fireplace?

  • You most certainly can replace your glass doors! Once you determine what type of fireplace you have either masonry or prefab, take your measurements, and shop for the door that fits your design. Then you can purchase your doors and install them!

What is a zero clearance fireplace door?

  • Zero clearance is another word for a pre-manufactured (prefab) door. If you have a prefab fireplace, you will need this type of door if you are looking to replace the provided doors. The prefab doors are made to be more efficient with heating and can assist with lessening your heat waste. Therefore, you will need to always make sure you are getting the correct type of glass door.

What does OEM mean?

  • OEM is an acronym for Original Equipment Manufacturer. Any OEM part is associated only with a specific manufacturer and cannot be used interchangeably with another fabricator's products. Keep scrolling to read more about OEM fireplace doors!

Where on the website can I find OEM fireplace doors?

  • Unfortunately, we don’t sell OEM fireplace doors for a few reasons.

  • First, we cannot offer you the same great free shipping with OEM fireplace doors as we can with the rest of our products. The special packaging that OEM doors require doesn’t qualify.

  • Customers generally want the entire replacement fireplace door and with OEM doors, you don’t really get that. Most of our customers are interested in the entire door because theirs has been damaged or is outdated. So, everything from the glass to the mounting hardware needs to be included.

  • Companies change designs and finishes over the years—sometimes even annually! When customers want to replace the original fireplace door, this can be a problem because the company may no longer carry that product as it was originally. Because of that, we offer complete fireplace enclosures with matching door and mainframe finishes.
