Zero Clearance or Masonry Fireplace?

If you’re considering installing a fireplace insert, knowing what type of fireplace you currently have will be helpful to you and your hearth dealer.

Your fireplace is likely either masonry built, or zero clearance. Masonry built fireplaces are usually constructed of brick or stone with fireboxes made of the same material, creating a solid barrier between the fireplace and construction materials. Generally the firebox has little to no metal, and may or may not have doors. Zero clearance fireplaces, on the other hand, are manufactured fireboxes that are fire-rated to that no (zero) clearance is required between the firebox and construction materials like wood framing and sheetrock.
