FAQ
What is a fireplace blocker?
A fireplace blocker is a removable cover designed to reduce cold drafts and heat loss through an unused fireplace. It typically attaches over the firebox opening or metal surround.
- Magnetic covers/blankets: Attach to steel or iron surrounds and can include insulation for better draft control.
- Insulation blockers/vent covers: Help limit airflow through the opening or louvers when the fireplace isn’t in use.
- Fireplace screens: Mesh or glass-style barriers that help guard against sparks and provide a child/pet barrier; they’re not intended to stop drafts.
Only use blockers on a completely cool fireplace, and remove them before lighting a fire.
What's the easiest way to block a fireplace?
One of the simplest options is a magnetic fireplace cover sized to your opening.
- Confirm material: Magnets stick to steel or iron surrounds (not brick, stone, glass, or aluminum).
- Clean and dry: Wipe the metal surface so magnets grip well.
- Center and attach: Align the cover, then press around the edges to reduce gaps.
- Check coverage: A slight overlap can help limit drafts.
For non-magnetic surrounds, consider a blocker designed for alternative attachment methods or use a free-standing screen for spark protection. Only apply covers to a cool, unused fireplace, and remove before burning.
How do I install a magnetic fireplace cover?
- Make sure it’s cool: Wait until the fireplace, doors, and surround are completely cold.
- Test magnetism: Magnets attach to steel/iron; they won’t stick to masonry or non-ferrous trim.
- Prep the surface: Wipe off dust and soot so the cover sits flatter.
- Position the cover: Center it over the opening with a small overlap for better sealing.
- Press to secure: Smooth from top to bottom and along edges to minimize gaps.
- Final checks: Ensure no vents or controls are obstructed. Store the cover away from heat when the fireplace is in use.
Remove the cover before lighting a fire.
How can I safely block off my fireplace?
- Only block when unused: The firebox and surround should be completely cool with no embers.
- Mind appliance type: For gas or vented inserts, follow the manufacturer’s guidance and avoid blocking air inlets or vents; consider consulting a qualified pro.
- Choose suitable materials: Look for covers labeled fire-resistant and intended for fireplaces.
- Maintain access: Don’t cover controls, pilots, or sensors.
- Remove before use: Take off the blocker before lighting any fire or activating a gas unit.
- General home safety: It’s a good idea to keep working smoke and carbon monoxide alarms in your home.
What size fireplace cover or screen should I buy?
Measure before you shop to help get a better fit.
- Magnetic cover: Measure the width and height of the metal surround or opening. Many customers prefer a cover slightly larger than the opening for overlap. Verify that magnets will sit on metal all around.
- Insulated blankets/blockers: Use the opening’s width/height and allow some overlap to reduce gaps.
- Screens (single or 3-panel): Measure the firebox opening. Choose a screen at least as tall as the opening and wide enough to cover it fully; 3-panel styles should extend past the sides for stability.
Compare your measurements to the item’s listed dimensions on the product page.
