Is cement board a good heat shield?
Safe wood stove installations require a heat shield that will prevent heat from the wood stove from creating a fire hazard in the building materials that form the exterior wall.
Hardi cement board is an inexpensive solution that will form the foundation of an effective heat shield for any application..
What can be used as a heat shield?
A brick, stone or tile heat shield is equally effective but in a different way. These dense materials absorb lots of heat and gradually release it as air circulates around them. The simplest masonry heat shield is a cement board that is separated from the wall by one-inch ceramic spacers.
Does cement board absorb heat?
Yes, HardieBacker® 1/4″ Cement Board is deemed noncombustible when tested to ASTM E 136 and can be used in conjunction with other noncombustible materials around a fireplace.
What material do you put behind a wood burning stove?
Brickwork and stone are popular choices and give a rustic, natural feel. Wood beams can be incorporated at the top of an alcove to give extra design flair or to form a mantlepiece. Tiles and metal are also popular choices for log burning stoves.
Is cement fire resistant?
The components of concrete – cement (limestone, clay and gypsum) and aggregate materials – are chemically inert and therefore virtually non-combustible. … Fire resistance refers to a material’s ability to stand firm in a fire while everything around it burns.
Is Durock cement board fire rated?
A Durock panel with a thickness of 1/2 or 5/8 inch can provide two hours of fire protection when installed correctly and in conjunction with all fireproofing construction materials.
How close can a wood stove be to a non combustible wall?
18 inchesAn unprotected stove pipe should be at least 18 inches from an unprotected wall or ceiling. And if the legs of the stove provide a clearance of less than 6 inches, the recommendation is to install 2 to 4 inches of hollow masonry with a sheet of 28-gauge sheet metal under it.
How do you protect a wall behind a wood stove?
If you want to keep the stove closer than the specified distance, you can put a ‘radiation shield’ between the stove and the wall, which will usually reduce the clearances by half. A radiation shield is any non-combustible material with an air space between it and the wall.
How close can you put a wood stove to a brick wall?
At least 36 inches of clearance must be allowed between the top of a stove and an unprotected ceiling. Brick or stone provide little or no protection for a combustible wall since they are good conductors of heat.
Can I drive without the heat shield?
Heat shields are important. Although you can technically still drive your car or truck without a heat shield, it’s a needed safety feature that was put on your car for a reason.
Can I tile behind a wood burning stove?
The most common way of doing this is to tile the wall or a portion of the wall behind the stove. Drywall is combustible and not a suitable material either for use behind the wood stove or for use underneath tile. Removing it from the wall behind the wood stove allows you to install cement backerboard instead.
How do you cut cement board?
The simplest way to cut cement backer board is to score the surface and snap the sheet along the scored line, similar to the way you’d cut drywall. In fact, you can use a drywall utility knife to score backer board, but a better option is a carbide-tipped scoring tool.
Can you paint cement board?
Do not paint a cement board unless you have thoroughly cleaned it first, or you may have problems with adhesion. … Unlike standard cement, which is not an ideal surface for paint adhesion, fibrous cement boards contain pores that soak in the adhesives within the paint, making the finish much more durable.
Is cement board considered non combustible?
Yes, HardieBacker® 1/4″ Cement Board is deemed noncombustible when tested to ASTM E 136 and can be used in conjunction with other noncombustible materials around a fireplace. This does not mean that clearances to combustible building materials can be reduced by using HardieBacker 1/4″.
How close can I put my wood stove to the wall?
The standard clearance recommended by the National Fire Protection Agency is 36 inches. This means that the back of the stove should be 36 inches away from any combustible material, such as woodwork, unprotected walls, furniture and even firewood.
What is considered a non combustible wall?
Well, my definition of a ‘non-combustible’ wall would be just that, no part of it would be capable of burning. … Heat shields are also available for use with single wall flue pipe — most often used for horizontal runs close to a ceiling.
What is the best material for a heat shield?
The rigid heat shield has, until recently, been made from solid steel, but is now often made from aluminum. Some high-end rigid heat shields are made out of aluminum sheet or other composites, with a ceramic thermal barrier coating to improve the heat insulation.
Can you use aluminum foil as a heat shield?
In summary, because of metal’s unique properties, it can be an excellent heat shield (such as when aluminum foil is wrapped around warm food) or an excellent heat sink (such as when metals fins are attached to computer chips).
