If you have an older masonry chimney, you most likely have a clay tile liner. While these liners are durable and long-lasting, the clay tiles do crack and break off over the years. Repairing clay tile liners can be costly and time-consuming, but, fortunately, there is another alternative. Hudson Chimney is proud to offer the HeatShield system to repair and reline clay tile liners. We have been certified by the company that manufactures HeatShield, so you can trust our skills, experience, and training to use this product properly and successfully. We are often asked about this relining system, so we would like to tell you more about HeatShield and how it can restore your chimney liner.
What exactly is HeatShield?
A specially created “Cerfractory” sealant, HeatShield was developed 20 years ago in Europe to restore your chimney to its original level of safety and efficiency. When your clay tile liner is damaged with cracks and gaps, it can be dangerous as these voids allow toxic gases like carbon monoxide to leak back into your home. An environmentally friendly product made from recycled and naturally occurring materials, HeatShield is a less expensive way of relining a chimney, compared to rebuilding your chimney or removing clay tiles to install a new liner.
How does HeatShield repair my clay tile chimney liner?
If Hudson Chimney determines that your liner simply needs repairing, we can use one of two HeatShield methods: the Joint Repair System, if only defective mortar joints are found, or the Resurfacing System, if you have both damaged mortar joints and other minor defects in the tile liner. With the Joint Repair System, we take a special foam applicator blade that has been customized to fit your chimney and place it down your chimney to position it below each gap or void. We then add the HeatShield Cerfractory Flue Sealant mixture to fill in every void. Once the voids have been filled, we will pull the blade upward, which will smooth the repaired voids. The Resurfacing System is very similar, except we will use a customized foam applicator plug. This plug will be placed at the bottom of your flue and attached to a winch at the top of the flue. A primer is applied first, and then we will add the HeatShield mixture. As the plug is pulled up by the winch, the mixture will be smoothed to the right thickness. For both systems, the work will be checked by viewing the footage from the video camera at the bottom of the blade or plug. This ensures the repairs have been done properly.
How can HeatShield replace my liner?
If your clay tile liner is damaged beyond repair, Hudson Chimney can use the CeCure Sleeve Relining System. This process begins with a coat of HeatShield, which is applied with the same type of plug used in the Resurfacing System. Next, the CeCure Sleeve, which is a ceramic insulation sleeve that has been reinforced with stainless steel fabric, will be lowered into your chimney and attached mechanically to the top of the chimney. We then pull the plug down the chimney to press it into the first coat of HeatShield. Finally, another coat of HeatShield will be applied over the CeCure Sleeve. This procedure will also be video recorded and viewed afterwards to be sure the sleeve is in the proper place.
