Screens, spark guards and doors — what each does
- Mesh screens / spark guards: the essential ember barrier for an open wood fire — freestanding, hanging, or pull-across mesh curtains. If you burn wood with the fire exposed, you want one.
- Glass doors: a hinged or bi-fold glass barrier across the opening. They add safety, reduce drafts, dress up the fireplace, and help seal it when it’s not in use.
- Combination doors with both glass and an integrated mesh screen behind, for flexibility.
An important safety rule for glass doors
Glass doors are not all created equal, and how you use them matters. On a wood fire, tempered glass doors should generally be fully open or fully closed while burning per the manufacturer — not cracked partway, which can concentrate heat and stress the glass. And doors for a gas fireplace or a wood insert have their own specific requirements — some sealed units must run with doors closed, others open. Using the wrong doors, or using them the wrong way, isn’t just cosmetic. We’ll make sure the set matches your fireplace type and that you know how to run them.
How doors help in our climate
Here’s the South Florida angle most door pitches miss: on a fireplace you rarely use, glass doors are a meaningful seal against the conditioned-air loss and humid-air intake that an open firebox allows year-round. Paired with a sealing damper or top-sealing damper, doors help close the fireplace off as a hole in your building envelope. So doors aren’t only about the fire — they’re about the 50 weeks a year there’s no fire.
Choosing and fitting a set
Doors are sized to the fireplace opening and come in a range of finishes and styles, so a good fit and a look that suits your surround matter. Masonry fireplaces take one kind of mounting; prefab units often require the manufacturer’s specific doors for that listed model. We’ll measure, help you choose a set that fits both the opening and the room, and install it so it operates smoothly — and we’ll steer you away from a door that isn’t right for your firebox, even if it’s the one you spotted first.
Questions people ask us
Do I need glass doors or just a screen?
If you burn wood with the fire open, a screen or spark guard is the essential ember barrier. Glass doors add safety, cut drafts, update the look, and help seal an unused fireplace against conditioned-air loss. Many people want both — doors for when it’s idle, a screen for when it’s burning. It depends on how you use the fireplace.
Can I close my glass doors while the wood fire is burning?
It depends on the doors and the manufacturer, but tempered glass doors on an open wood fire are generally meant to be fully open or fully closed — not cracked partway, which can stress the glass. Gas units and inserts have their own rules, some requiring doors closed and some open. Matching the right doors to your fireplace and using them correctly matters for safety, so we’ll set you up properly.
Will new doors really help my energy bills?
On a fireplace you rarely use, yes — glass doors reduce the conditioned air escaping up an open flue and the humid air coming in, which in our A/C-heavy climate is a real year-round loss. They work best paired with a sealing damper. It’s a modest but genuine improvement, on top of the safety and looks.
