Hearth boards, also known as stove boards or hearth pads, are primarily used to insulate your floor from the heat produced by a wood stove or furnace. If you're interested in one of these appliances there's a good chance that you're going to have to install it with a hearth board in order to maintain safe clearances. But even if your stove doesn't require a hearth board, you may want to consider getting one to use as a hearth extension.
What material is the UL-1618 type 2-36x36 made of?

The board is constructed of USG brand Micore mineral fiber board, enshrouded in a 30 gauge steel jacket for appearance and strength.

I own a cast iron stove in a small cabin and it doesn't have a lot of room. Do I need a type 1 or 2 pad?
By eFireplaceStore on August 25, 2014
This model of stove does require a floor protector with an R value, so a Type 2 protector must be used. The Hy-C 36-inch x 52-inch Type 2 UL1618 Black Stove Board is the smallest factory built board we offer to the 27 by 51 inch floor protector requirements this stove lists. Anything smaller would need to be custom made.

We received a fire pit for Christmas and would like to use it on our wood deck. What do we need to put under a fire pit in order to keep it from damaging the deck? The only stove boards that we can find are for interior use. Would bricks stain the deck if we put them directly onto the wood?
By eFireplaceStore on December 29, 2014
Depending on the model of fire pit you received, something as simple as a layer of concrete pavers can be used. As you have found, most hearth pads are indeed designed for interior use and the insulating mineral board inside them does not do well when exposed to moisture. Concrete pavers with no colored dye added to them should not stain the deck.

Is there a code for the hearth in front of my fire place? Can I just have my wood floor there? Does something else have to be there and does it have to be a certain size?
By Collin C. - NFI Master Hearth Professional on November 14, 2013
Per the UL 127 standard for wood burning fireplaces, a hearth extension must be used. For a fireplace with an opening of less than 6 square feet, the hearth protector must extend 8 inches beyond each side of the opening and 16 inches in front of the unit. For a fireplace with an opening of 6 square feet or greater, the hearth protector must extend 12 inches beyond each side of the opening and 20 inches in front of the unit.

We have a wood burner that was used as a fireplace insert and is not used as a free standing firebox. We want to put something directly on the sides of the box and back to give it a finished look. Can any of these boards that are fireproof be used this way? If not, what would you suggest?
By Chris C. on March 4, 2015
These boards are more commonly used as a means of protection to reduce clearance requirements to combustible wall board or flooring material beneath free standing stoves. If you are looking to finish out around a fireplace, this would be better accomplished utilizing a non-combustible board such as Durock, and then finish atop it with a ceramic tile, granite slab, or other non-combustible finishing material.

I have a wood pellet stove and want to put a stove board under it. I see there are two types of boards, Type I and Type II. What is the difference? I see they are only 5/8” thick. Does that offer enough protection if the pad will be on top of a plywood surface?
on November 9, 2012
The answer to your question all depends on your stove and what the manufacturer of it requires. As far as the types are concerned, Type I boards are ember protectors only. They keep embers from landing on an adjacent combustible surface. Type II boards offer thermal protection in addition to ember protection. These boards have a higher R value.

I have an antique parlor stove & will required a stove board 6' x 6' square. Do you carry anything in this size & if so, is it UL listed & what is the R rating?
on November 9, 2012
Unfortunately, the largest square pre-manufactured stove boards that we carry measure 48" x 48". This is because shipment of anything larger than this would have to be done by a specialty freight carrier. Most floor protection that is larger than this would need to be custom made on site, utilizing concrete board and tile or an equivalent noncombustible material.

I need a floor pad measuring 48 x 60. I don't see that as a specific size. Do you have something close?
on November 9, 2012
While we do offer 48" x 48" and 36" x 52" boards, we do not carry anything that is larger than these dimensions. This is largely due to the shipping limitations of boards that are any larger than this. Most larger hearth pads must be site built out of concrete board and a ceramic tile or brick of your choosing.
By Loretta on November 9, 2012
We just bought a an antique parlor stove & code requires 18" of space around the stove itself. I'm looking for a stove board that would be 5-1/2' square. Largest size I see you have is 4 x 4.
Can you help me please?
on November 9, 2012
Unfortunately, you are correct. We do not currently carry a stove board larger than 48" square. Further, we do not customize any of our products. We apologize for the inconvenience.

We would like to use a hearth pad, but the Enviro stove requires venting through the floor of the mobile home. Can we cut a hole in the pad to accommodate the requirements?
By Tyler M. - NFI Certified Specialist on September 4, 2013
We do not recommend cutting into the stove boards or hearth boards. Doing so with compensate the effectiveness of these boards and cause potential issues with thermal and spark protection.

Are either ok to use on the wall behind the woodstove? What is the difference? I need something about 36 x 52".
By Collin C. - NFI Master Hearth Professional on April 29, 2014
Can I just order the framework for the hearth pad, so I can put my own tile in it?
By Collin C. - NFI Master Hearth Professional on December 3, 2012
Unfortunately, no. The metal frames for the hearth pads we sell are cut and welded together on site by the manufacturer. It would be necessary to purchase angled steel to construct your own frame or have a local fabricator cut the steel components to the required size so that they could be screwed or welded together on site.

Do you make/sell hearth boards (48 X 48) with an R Factor equal to or greater than 2?
By Tyler M. - Fireplace Specialist on February 26, 2013
Our other 48" x 48" boards have varying R-values, though none are greater than 2.

What are the dimensions for the corner pad that is 40 x 49? Is the long side 49" and the short cut side 40"?
By Magan B. on July 23, 2013
The length is 40" and width is 49".

What is the difference between type 2 stove board and 1 UL stove board? I need to protect a wood deck from an outdoor wood portable fire pit.
By eFireplaceStore on June 16, 2014
Type 1 stove boards offer ember protection only. They are excellent for protection against falling coals or even a log that rolls out of position, but they do not offer any kind of thermal insulation. Type 2 stove boards offer ember and thermal protection. They will utilize a layer of built in material, usually mineral board, which helps to shield the area below from excessive heat. If the fire pit is low to the ground and could potentially damage a combustible surface beneath it, the Type 2 board would be the product to use.
