Fire safety codes require an 1/8 inch gap around a fireplace door for proper air flow and to prevent overheating. So while our air sealed enclosures are not truly 100% air tight, it's the pre-installed fireplace door gasket seal around the edge of the doors that prevents them from being drafty. We have custom sizing available to ensure that your wood burning fireplace glass door fits snuggly in your firebox for optimized efficiency.
Some of our energy efficient enclosures come with tempered safety glass, while others offer the added bonus of ceramic glass door panels! High temperature pyroceram allows you to burn a fire while your fireplace doors are shut, without having to worry about the glass panes breaking under extreme heat exposure.
Finish colors, various methods of spark protection, and damper options are also available when selecting one of these air seal enclosure with a fireplace door deal. Our high-quality steel doors are American made, and free shipping is included with all of our products.
Recently, we had some customers ask if they could install an air tight ceramic glass door on a see through fireplace in order to burn a fire with the doors closed. The answer is yes. Ceramic glass has a higher heat rating than tempered glass. It does allow you to burn a fire with the doors shut without shattering from the extreme temperatures generated from within the firebox. Tempered glass fireplace doors will shatter if closed while the flames are going. In addition, the gasket seal around the edges of our ceramic glass doors prevents the enclosures from being too drafty.
Another question that was asked: "Is it necessary to purchase a ceramic glass door for each side of the see through fireplace, or can one opening be closed off with a single pane of ceramic glass or masonry?" While two air tight ceramic glass doors may seem like a substantial investment, it is the safest choice for this situation. Fire safety codes require proper airflow and draw of the fireplace and chimney. As mentioned, these codes also require a minimum 1/8 inch gap around the fireplace door (which our air tight enclosure do abide by) to prevent overheating. People with see-thru fireplaces, usually buy a door for each side.
As a safety precaution related to this case study, remember that you should always burn a fire with open doors if using tempered glass doors. You may keep your doors closed ONLY if you are installing ceramic glass fireplace doors. We highly recommend purchasing the same type of glass fireplace enclosure for both sides of a see through application.
