In chimneys with more serious defects or unlined chimneys, HeatShield® can be used with the CeCure® Sleeve Relining System. The CeCure® Sleeve is a thin profile, ceramic insulation, reinforced with stainless steel fabric that is sandwiched between two coats of HeatShield® Cerfractory® Flue Sealant.
To reline your chimney with the HeatShield® CeCure® Sleeve Relining System (patent pending), an applicator plug is placed at the bottom of the flue and attached to a winch at the top of the chimney.
First, a coating of HeatShield® Cerfractory® Flue Sealant (with an added drying accelerator) is applied to the flue walls as the applicator plug is pulled upwards by the winch.
Second, a custom fitted, “CeCure® Sleeve” is lowered into the chimney and mechanically attached to the top of the chimney. The CeCure® Sleeve is a high density, low profile, ceramic insulation sleeve which has been reinforced with a special stainless steel fabric.
The applicator plug is then pulled downward through the CeCure® Sleeve to press it firmly into the first coating of HeatShield® Cerfractory® Flue Sealant with the added drying accelerator.
With the applicator plug at the bottom of the CeCure® Sleeve, the sleeve is temporarily clamped into place.
Lastly, another coating of HeatShield® Cerfractory® Flue Sealant is applied over the CeCure® Sleeve. Your HeatShield® Installer will then use a video camera to verify that the CeCure® Sleeve has been completely coated, ensuring the integrity of your newly relined chimney.
