Your chimney may look good from the ground up, but can still have hidden issues inside. Heat Shield® can restore your chimney’s clay liner and save you the expense of rebuild or relining with a stainless steel chimney liner.

Fire and Health Risks

Gaps between flue tiles caused by eroded mortar. Cracked flue tiles caused by a chimney fire, lightning strike, poor workmanship or the ongoing settling of your home. Flaking flue tiles (spalling) caused by exposure of corrosive chemicals and moisture from combustion. All of these are hidden dangers to your chimney that can cause fire and health risks.

These issues, 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.

Gaps and cracks can also 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 catches fore, serious damage can occur because the fire can no longer be contained within the flue.

Why Heat Shield® ?

HeatShield® is a chimney liner repair system that eliminates the hazards and draft problems caused by gaps, cracks and spalling in otherwise sound masonry chimneys. HeatShield® is an eco friendly product made from recycled and naturally occurring materials.

Developed over 20 years ago, Heat Shield® Cerfactory® technology is a hybrid (ceramic/refactory) coating. Its has been proven to withstand moisture, corrosive flue gasses and temperatures in excess of 2900° F (holding a ‘super-duty’ rating per the American Society of Testing and Materials). It surpasses both National Fire Prevention Association (NFPA) and International Residential Code (IRC), which require only a ‘medium-duty’ refactory mortar for use in fireplaces and chimneys.

How Heat Shield® Works:

heatshield-resurfacing-winchWe restore your chimney’s clay flue by resurfacing the interior. A custom-made foam applicator is placed at the bottom of the flue and attached to a winch on top of the chimney.

We first apply a ‘tie coat’ material to the flue walls as the applicator is pulled upward by the winch. The ‘tie coat’ cleans any remaining dust in your flue and acts as a primer for the HeatShield® Cerfractory® Flue Sealant.

After the tie coat dries, the HeatShield® material is then applied onto the flue at a thickness of about ¼ inch with the applicator being lifted upwards by the winch. This unique application method is known as ‘slip casting’.

Our service team at Anderson’s Chimney and Masonry Services has gone through extensive factory training and is Heat Sheild® certified.
