What kind of glass is in fireplace doors?
Only the two varieties of glass listed below are employed in fireplaces; both are robust and offer thermal protection; the only distinction is that one can resist a higher level of heat than the other, allowing it to be closed while a fire is being burned.
- Tempered glass
- Ceramic glass or polycrystalline
Let’s talk first about both types of glass in the next section.
Tempered glass fireplace doors
So as you can see tempered glass fireplace doors need to be opened while burning other wise they can shatter because of the high temperatures of your fire.
Because the vast majority of fireplace doors are constructed of tempered glass, practically all of them should be opened when burning.
Ceramic glass fireplace doors
Ceramic glass doors are three to four times the price of normal tempered glass, but they are engineered to withstand the extreme heat generated by fireplaces.
Ceramic glass fireplace doors can be closed and are most often used with fireplaces that have air-tight doors and work as an air-tight system similar to a free-standing wood-burning stove
One thing to keep in mind is that while replacing the glass in a pair of custom fireplace doors is permitted, doing so with prefabricated fireplace doors is against the fire code.
How hot do fireplace doors get?
Tempered glass fireplace doors can withstand temperatures of up to 450 degrees, while a normal fireplace can reach temperatures of 500 to 1200 degrees while burning wood.
Ceramic glass fireplace doors are designed to withstand temperatures up to 1400 degrees
So it is safe to say that if a fireplace can reach 1200 degrees when burning wood then the fireplace doors can reach the same temperature when closed.

Protection and Safety Features
When it comes to wood burning fireplace glass doors, protection and safety features are crucial. Glass doors help to keep the heat in your home and prevent sparks and embers from flying out of the fireplace and into your living space. Here are some important safety features to consider when purchasing glass doors for your wood burning fireplace.
Embers and Sparks
Embers and sparks can easily pop out of a wood burning fireplace and cause damage to your home or even start a fire. Glass doors act as a barrier to prevent these potentially dangerous elements from escaping the fireplace and causing harm. Look for glass doors that have a tight seal to ensure that no embers or sparks can escape.
In addition to glass doors, fireplace screens can also provide an extra layer of protection against embers and sparks. Screens can be used in conjunction with glass doors or on their own. They are especially useful if you want to enjoy the warmth and ambiance of the fire while keeping small children or pets at a safe distance.
When choosing a fireplace screen, make sure it fits securely in front of the fireplace opening and is made of durable materials that can withstand high temperatures. Some screens also come with decorative designs that can add to the aesthetic appeal of your fireplace.
Overall, it is important to prioritize safety when using a wood burning fireplace. Glass doors and fireplace screens can provide an extra layer of protection against flames, popping out embers and sparks. Consider investing in these safety features to enjoy the warmth and beauty of your wood burning fireplace with peace of mind.

Fireplace doors that can be closed during a fire

What happens when you close the glass doors on a fireplace?
People frequently ask, “Why do I see so many photographs of wood-burning fireplaces with their glass doors closed since they are not supposed to be closed while burning?” The reason for this is that manufacturers of fireplace doors use fake fires behind the doors to make them more visually appealing to buyers.
When you have a fire, always keep the doors open. Although the companies that offer aftermarket fireplace glass doors would have you believe otherwise, doing so is actually not advised with tempered glass, and you will most definitely save yourself cleaning up a mess.
Do fireplace doors help with efficiency?
At best, an open hearth fireplace is just 10% efficient, which means 90% of the heat energy you paid for escapes through your chimney and leaves your home.
Additionally, even with the doors closed and the fireplace off, room air can still draft up the chimney and escape, making the furnace work harder to keep the house warm.
Is a fireplace more efficient with the doors open or closed?
As previously established, tempered glass fireplace doors cannot be closed when a fire is burning, and as will be explained below, closing them when there is no fire also makes no notable difference.
Using glass fireplace doors can improve efficiency, but only by about 20%.
Even with both the doors and the damper closed, most fireplaces still lose some heat, so closing them both will help you increase efficiency somewhat but not totally.
So “Is a fireplace more efficient with the doors open or closed?” as you can see it will make your fireplace a bit more efficient but not enough to write home about.
If you decide to add new doors to your fireplace look at it more as aesthetics than savings.
Do glass doors make fireplaces more efficient?
Tempered glass doors cannot radiate heat into a room, So then do fireplace doors block heat. Yes because they are not made to radiate, instead, you must leave them open so that you can feel the heat radiate from the flames.
Standard bifold fireplace doors really only have two functions.
- They are intended for aesthetic purposes
- To stop cold drafts from entering your room.
Why does the fireplace burn better with the doors closed?
If you feel that your fireplace is burning better with the doors closed it is probably because the air is rushing in the cracks and crevices and making the flames dance quickly but this doesn’t mean it is burning efficiently.
Closing the doors will reduce the amount of oxygen that may reach the fire, it needs oxygen to burn, and this will not prolong its life or burn more efficiently.
Another advantage of leaving the doors open is that there is better airflow, and better airflow improves combustion, so if the doors are being used as intended, your fire should burn hotter and provide more heat into the room.
leaving the doors open will also help reduce creosote in your chimney because flue gasses will be able to move freely and quickly up the chimney not allowing them to accumulate on the sides of the inner lining.
