Masonry Chimney Re-lining

At Estates Chimney, located in Chalfont, we specialize in providing exceptional masonry chimney relining services to ensure the safety and efficiency of your chimney system. Our certified technicians, experienced in chimney and vent services, prioritize your peace of mind by conducting thorough inspections, repairs, and chimney relining according to industry standards.

Comprehensive Chimney Relining Process

Our chimney relining services are designed to address issues related to chimney deterioration and ensure proper venting of smoke and gases. Our comprehensive relining process includes:

Chimney Inspection: We begin by conducting a detailed inspection of your chimney to assess its condition, identify any structural damage or deterioration, and determine the appropriate relining method.
Determining the Relining Method: Based on the inspection results, we determine the most suitable relining method for your chimney. This may involve stainless steel liners, clay tile liners, or cast-in-place liners. The chosen method will depend on factors such as the condition of the existing chimney liner and the specific requirements of your chimney system.
Chimney Relining Installation: Our skilled technicians proceed with the relining installation process, following the selected method. This may involve removing the existing liner, repairing damaged masonry, and installing the new liner. We use high-quality materials that meet industry standards to ensure optimal performance and safety.
Testing and Compliance: After the relining installation, we conduct thorough testing to ensure proper venting and compliance with safety regulations. This may involve performing smoke tests, pressure tests, or other necessary assessments to verify the integrity and efficiency of the newly installed chimney liner.

Introducing Supaflu®

SupaFlu - The Poured Chimney Flue Lining System!

Supaflu® is a cutting-edge chimney flue lining system designed specifically for masonry chimneys. It utilizes a revolutionary "cast-in-place" technique, providing an innovative solution for lining masonry chimneys. This unique system comprises a factory blend of proprietary cast-in-place aggregates, ensuring top-notch performance and durability.

Originating in Europe over 50 years ago, Supaflu® has been widely adopted in the United States and Canada since the late 1970s. The process involves pouring and casting the chimney lining in place within the existing masonry structure. By employing modern equipment, advanced technology, and efficient installation methods, the Supaflu® liner offers a reliable and practical alternative to the traditional approach of chimney demolition.

Advantages of Supaflu®

One of the key advantages of Supaflu® is its lightweight and insulating properties, making it an ideal choice for withstanding high service temperatures. This cementitious material is engineered to endure extreme conditions while maintaining its structural integrity.

Choosing Supaflu® for your chimney flue lining needs means investing in a proven and effective solution that will enhance the efficiency and safety of your chimney. Say goodbye to the hassle of tearing down your chimney with this state-of-the-art poured lining system.

How it Works

Step 1: Flue Preperation

Prior to installation, the chimney is inspected, cleaned, and prepared using industry recognized procedures & equipment. Should the flue already be lined, the existing liner is removed. All openings such as clean-outs, thimbles, and fireplace openings are sealed and secured.

Step 2: Material Installation

The proper former is calculated for your heating appliance. The inflatable rubber former is then lowered into the flue, inflated, and centered. The Supaflu lining material is prepared (adding water) then pumped into the chimney from the top. All voids, cracks, and holes are filled with the slurry.

Step 3: Former Removal

After the new Supaflu liner has fully cured, the former is deflated and removed from the flue, leaving a smooth, round, one-piece liner. the new crown is and wash is installed at this time.

Why it Works

Supaflu Physical Properties of Flue Materials

Supaflu chimney liners offer many benefits including: improved structural stability, ease of maintenance, and suitability to all fuel types, but most importantly improved efficiency and added safety.

Supaflu is designed to insulate your chimney while providing an effective barrier between the flue gases and your living quarters. Because of its liquid consistency, Supaflu seals all cracks and pores, greatly reducing the chance of your exposure to toxic gases.

As an insulator, Supaflu is superior. In fact the R-value is 500% greater than clay tile liners. This insulation ensures that flue gases remain hotter and more buoyant, thus improving overall venting efficiency and reducing buildup within the flue.

Additionally, your chimneys exterior surface temperature will be lowered, reducing the chance combustible materials surrounding your chimney may ignite. Supaflu is non-corrosive and is free of asbestos. Also, when subjected to alternate freeze-thaw cycles, Supaflu showed no signs of surface degradation.

Physical Properties

Specific Heat is the amount of heat required to raise the temperature of 1 pound of material by 1° Fahrenheit. For example, the specific heat of water is 1 btu/lb. F.

The Product-Unit Weight when multiplied by the specific heat represents the amount of heat required to raise the temperature of 1 ft³ of material by 1°F. The lower value the less time it takes to warm up or to cool down. For a flue lining material, a lower value is desirable so that when the appliances attached to the flue start firing, the flue walls heat up more quickly thus reaching their working temperature faster. This effect will reduce condensation and creosote build-up during a cold start and provide an effective draft more quickly.

Thermal Conductivity (also known as k-factor) determines the rate at which heat loss occurs through the material. For a chimney flue liner, the value of thermal conductivity should be low so that most of the heat of the flue gases is contained within the flue and only a small amount of heat loss occurs through the flue walls.

Thermal Resistivity (also known as the R-factor) is the reciprocal of thermal conductivity. Therefore, we would look for a high value for a chimney flue.

Introducing HeatShield Cerfractory Flue Sealant

Your chimney's structural integrity is crucial for the safe and efficient operation of your fireplace or heating appliance. HeatShield Cerfractory Flue Sealant offers a reliable solution for repairing and restoring damaged chimney liners, eliminating the need for costly rebuilding or relining with a stainless steel chimney liner.

Key Features:

Comprehensive Repair System: HeatShield is a professional chimney liner repair system designed to address gaps, cracks, and spalling in otherwise sound masonry chimneys. By sealing these defects, it restores the integrity and functionality of your chimney.
Saves Costs: Instead of undertaking expensive chimney rebuilding or relining projects, HeatShield allows you to restore your chimney's flue liner, providing a cost-effective solution without compromising safety or efficiency.
Custom Application by Trained Professionals: HeatShield Cerfractory Flue Sealant is professionally applied by factory-trained chimney professionals. Their expertise ensures proper installation and adherence to quality standards.
Resurfacing System: For chimneys with cracked or spalled flues that are structurally sound, the Resurfacing System is used. A custom-made foam applicator plug is placed at the bottom of the flue and attached to a winch on top of the chimney.
Tie Coat Application: A "tie coat" material is first applied to the flue walls as the foam plug is pulled upward by the winch. This step cleans any remaining dust in the flue and acts as a primer for the HeatShield Cerfractory Flue Sealant.
HeatShield Application: After the tie coat dries, the HeatShield material is applied onto the flue at a thickness of approximately ¼" using the foam plug as it is pulled upward by the winch. This unique application method, known as "slip casting" or "slip cast extrusion," ensures thorough coverage and optimal sealing.
Video Scanning Verification: To ensure the complete sealing and smoke-tight integrity of your newly restored chimney, your professional HeatShield Installer conducts a video scan of the repaired flue, providing visual confirmation of the successful restoration.

By choosing HeatShield Cerfractory Flue Sealant, you can address chimney liner issues, enhance the safety of your fireplace or heating appliance, and restore the optimal performance of your chimney system.
