Heatshield Chimney Liners

by | Oct 9, 2017 | Chimney Maintenance | 0 comments

Every chimney needs a liner to be safe and effective. The chimney liner has many jobs: to protect the masonry from corrosive chemical byproducts, to resize a too-large chimney, to protect the home from carbon monoxide intrusion or heat transfer, and to provide a smooth surface for optimum air flow. When a liner becomes damaged for one reason or another it may need to be replaced. Chesapeake Chimney & Co. is proud to offer HeatShield® lining repairs for minor and major flue liner problems.

Using HeatShield® Cerfractory® Flue Sealant, a qualified technician can restore a damaged liner using a special product that a technician applies using special tools, then it air cures to a hard ceramic like material that is moisture and corrosion resistant. Minor damage such as gaps in the the lining, damage to the joints, and spalled flues can be repaired using HeatShield® sealant. It is applied to fully restore the liner, provided that the chimney itself is otherwise sound.

Repairing Major Damage With HeatShield®

When your worn out liner needs to be replaced, you don’t have to look further than HeatShield®. Using a method called the CeCure® Sleeve Relining System, your technician applies HeatShield® before slipping a CeCure® sleeve into the flue. It is a ceramic insulation sleeve, reinforced with stainless steel fabric. The sleeve is trapped in place with another layer of HeatShield® Cerfractory® Flue Sealant and then air cures for a smooth, durable finish.

CeCure® Sleeve Relining System Step-by-Step

  1. An applicator plug is placed at the bottom of the flue, and attached to a winch installed temporarily at the top of the flue.
  2. The applicator plug is pulled upward, coating the walls of the flue with HeatShield® Cerfractory® Flue Sealant as it rises.
  3.  A custom CeCure® sleeve is slipped into the flue and mechanically attached to the top of the chimney.
  4. The applicator plug is pulled downward, firmly pressing the sleeve into the coating of HeatShield®.
  5. A final coat of HeatShield® is applied to the CeCure® sleeve as the applicator is pulled upward again.
  6. The technician uses a video scan to check that the CeCure® sleeve is completely coated and the relining was successful.

When it comes to relining systems, we at Chesapeake Chimney & Co put our trust in HeatShield® products time and again. Developed over 20 years ago, this “cerfractory” technology is the best of both worlds, made of both ceramic and refractory materials. It withstands flue gases, moisture, and temperatures in excess of 2900°F. Additionally, a HeatShield® liner is safe for use with any fuel type, unlike clay tile liners. Every HeatShield® repair or relining is covered by a 20-year material warranty, is eco-friendly, and affordable. When you’re choosing a new liner, or liner repair, choose HeatShield®.
