16 inches

Likewise, what can I use for a fireplace hearth? Marble is softer than granite but still prized as a hearth material because it is durable and heat resistant. It is formed from limestone and tends to chip fairly easily, but because of its excellent heat resistance, it can be used with gas, electric and wood fires.

Besides, how do you extend a fireplace hearth?

Also, the hearth extension must extend at least 16″ from the front of the fireplace and 8″ on the sides for smaller fireplaces. When the opening of the fireplace is at least 6 square feet, the hearth extension needs to extend at least 20″ from the front of the fireplace, and 12″ on the sides.

Do I need a hearth for my fireplace?

Most modern gas only fireplaces with fixed glass do not require a hearth extension. The manufacturers usually require a 36" clear space in front (no furniture, etc.). Now if this was a wood burning fireplace that had a gas insert, the hearth extension would still be required. Once wood burning, always wood burning.

What is the best material for fireplace hearth?

Granite is the best fireplace hearth material for solid fuel burning fires. However, to withstand the heat, you need to get one that has been 'slabbed'. This means that it has been cut into pieces and mounted in concrete to give it space to expand as it heats up.

Is a hearth necessary?

Their recommendation was that since the fireplace COULD be used to burn wood, then a hearth is required by code. But technically, since the gas logs do not emit sparks or embers, and they are raised well above floor level, a hearth serves no purpose.

Does a hearth have to be raised?

The perimeter of the hearth should be clearly defined by either using a raised edge or by raising the level of the hearth in relation to the floor. The hearth should extend at least 150mm out from the stove at the sides and 300mm in front.

What is the purpose of a fireplace hearth?

Hearths were created to serve more of a purpose than strictly a decorative element, they provide a safer fireplace area, and prevent fire hazards. The floor of the fireplace extending into the room is there to prevent burning embers or logs from falling onto your floor and damaging it or even causing a fire.

Do you need special tiles for a fireplace?

Short answer: Yes, absolutely, but we would recommend using porcelain tiles or hardier floor-suitable ceramic tiles, which are very heat resistance. We'd also recommend using Palace Heat Resistant Adhesive, and keeping a gap of 6 inches around the back and sides of your stove.

What does zero clearance fireplace mean?

The term zero clearance refers to how close a fireplace can be to material that is combustible, typically framing. Because zero clearance fireplaces feature a larger quantity of insulation that do masonry fireplaces, it is not necessary to reserve a buffer zone between combustible materials and your fireplace.

How does fireplace insert work?

An insert is basically a fireproof box that's surrounded by steel or cast iron and fronted by insulated glass, creating a closed combustion system. The steel or cast iron helps to trap the heat. Some inserts have a blower that pushes the hot air back into the room through front vents.

What is the most heat resistant stone?

Granite is often billed as indestructible, and it's true that it can last a lifetime with proper care. This type of natural stone has excellent heat resistance, especially when compared to most countertop materials like laminate, butcher block, and even marble, but this doesn't mean it's impervious to heat damage.

Granite hearths in a single piece can not be used for soild fuel as granite has no heat resistant properties and when used under the heat from solid fuel it will simply crack down the centre, when in one single piece they are designed to be used for gas or electric use where the heat generated is not enough to damage
