Restore the Integrity of Your Chimney
HeatShield is a specially formulated "Cerfractory" sealant material that restores the integrity of your chimney's flue to vent hazardous flue gases from your home. It eliminates the dangers in your chimney caused by gaps, cracks and spalling.
Anatomy of Your Chimney
Whether your masonry chimney is used to vent a fireplace, woodstove or furnace, most have sections of clay flue tile stacked one on top the other to form a liner called the flue.
The flue liner should be tightly sealed to protect the integrity and efficiency of your chimney. But over time, hidden dangers can develop that will compromise the safety and efficiency of your chimney.
---------
Are There Hidden Dangers In Your Chimney?
Deteriorated mortar joint between flue tiles
Gaps Between Flue Tiles
The combustion process creates noxious gases that can contain creosote/soot, carbon monoxide and corrosive chemicals. The purpose of your chimney is to safely vent these hazardous flue gases from your home.
Flue tiles are typically sealed with mortar to keep these gases within the flue. But over time, the mixture of heat, moisture and chemicals will erode the mortar, leaving gaps or voids between flue tiles.
------------
Cracked Flue Tiles
Flue tiles can crack due to "sudden occurrences" such as a previous chimney fire, lightning strike, or seismic event. Cracks may also be caused by poor workmanship or the ongoing settling of your home.
Spalled flue tiles
Flaking Flue Tiles (Spalling)
Years of exposure to corrosive chemicals and moisture from combustion can attack clay flue tiles, causing pieces of the flue liner to flake off or delaminate, a process called spalling.
How These Hidden Dangers Can Affect You
Fire & Health Risks
These defects, no matter how small, can begin a process that will further erode the chimney and can pose a threat to your family's health. When heat, moisture and gases escape through gaps and cracks in your chimney, they can deteriorate your chimney from the inside out. More importantly, the gaps and cracks can cause health risks, by allowing poisonous gases to escape into your home.
Combustible creosote or soot can also escape through these openings and build up outside the flue liner. If the creosote were to catch fire in this area of your chimney, serious damage can occur, because the fire can no longer be contained within the flue. Pieces of flue tile that flake off due to spalling can form dangerous blockages within your chimney.
Loss Of Efficiency
Chimneys, to work correctly and efficiently, must be gas tight and free of gaps and cracks. Gases rising up through your chimney are similar to liquid being sipped through a straw. If the straw has a crack or hole in it the liquid will not flow effectively through it.
Gaps and cracks allow excess air into your chimney, slow the updraft and make it harder for smoke and gases to rise up and out.
Hence, the fireplace, woodstove or furnace will perform poorly, resulting in the loss of heat efficiency.
HeatShield Restores The Integrity Of Your Chimney
HeatShield is a specially formulated "Cerfractory" sealant material that restores the integrity of your chimney's flue to vent hazardous flue gases from your home. It eliminates the dangers in your chimney caused by gaps, cracks and spalling for years to come.
By using either the Joint Repair System or Resurfacing System, depending on the defects found, your chimney will be restored to its original peak level of safety and efficiency.
-----------
| Joint Repair |
Resurfacing |
For chimneys that only require repair of gaps caused by defective mortar joints, the Joint Repair System is used with a video camera attached to verify repairs. |
For chimneys with cracked or spalled flues, that are otherwise sound, the Resurfacing System is used to apply a coating over the entire flue. Cameras are used to verify repairs.
