What is HeatShield technology and How Does it Work?

HeatShield® is a chimney liner repair system that restores the chimney to its full safety and function in one easy process. It has been intensively tested and is considered a “Super Duty” refractory mortar. It is affordable and long-lasting. So, what is it?

HeatShield® Cerfractory® Technology

The HeatShield® difference is that it combines the strength of ceramic and the heat resistance of refractory cement to create the cerfractory technology that can repair your joints, resurface your chimney, and assist in lining. When an installer is trained and certified to apply HeatShield® in the field, he’ll do so by simply mixing water with the powder. This allows for less waste and keeps costs low. At Magic Sweep, we trust HeatShield®, and we’re proud to offer HeatShield® repairs and relining with the same great service and professionalism we’ve offered for years here in Chesapeake.

HeatShield® Joint Repair System

When joints become damaged, they not only create gaps, but it also create rough areas that disrupt the flow of air, which brings down the efficiency of the chimney. When this happens, the gaps commonly get bigger and worsen until a bigger problem arises in the flue. Using HeatShield® Cerfractory Technology, we can efficiently fill these gaps using a foam applicator blade, which custom fits your flue. After application, we check the system using video technology to ensure it works properly.

HeatShield® Resurfacing System

Over time, even expensive and properly-installed liners can become damaged. Cracks, gaps, and spalling masonry can become a problem–especially when a chimney is neglected and necessary maintenance appointments are forgotten. We can resurface the entire flue by using HeatShield® Cerfractory Technology. First, the foam applicator is made and placed at the bottom of the flue. It is then hoisted up as it applies a “tie coat” material to the walls. Once this coat dries, we apply HeatShield® in the same manner. This process is repeated once more, and then the job is completed with a video scan.

HeatShield® Cecure® Sleeve Relining System

Both resurfacing and relining work as a liner for your flue, and it’s safe for all fuel-types and long lasting, while also properly-sized–just as if you had a new liner. However, with the HeatShield® Cecure® Sleeve Relining System, nothing has to be removed from the flue. This is less disruption to the home as the HeatShield® material goes directly over the damaged portions. First, HeatShield® Cerfractory® Flue Sealant is applied using the custom foam applicator. Then, a CeCure® Sleeve made of high-density, low profile, ceramic insulation, reinforced with stainless steel fabric is placed inside the flue and pressed firmly into place using the foam applicator. The job is finished when another coat of HeatShield® Cerfractory® Flue Sealant is applied over the sleeve. This work is also checked using a video scanning system so that you have the verification of its safety and installation.
