All this is further explained here. Beside this, is cement board fire resistant?
Hardiebacker is a brand name for a line of fiber cement boards used in construction projects. This material has strong moisture-resistance capabilities and is also heat resistant, making it an ideal liner for projects around your fireplace.
Beside above, does drywall have a fire rating? Drywall is relatively fireproof, but manufacturing processes such as adding glass fibers can increase the resistance. Drywall is relatively fire resistant. It's composed of gypsum pressed between two sheets of thick paper. Gypsum is a soft mineral that by itself is not flammable.
Consequently, is DensShield fire rated?
DensShield Tile Backer is composed of a water-resistant treated core that is covered front and back with fiberglass mats. DensShield Tile Backer has been shown to be excellent for tile and non-tile installations in wet and non-wet applications, in areas of high humidity, and in appropriate fire-rated wall assemblies.
Which side of durock goes out?
Screw the board in place away from the edges. Cement board has a smooth side and a rough side. Face the rough side out if you will be using thin-set mortar adhesive to install the tile but the smooth side out if you will be using latex mastic.
