Flues & Chimneys

Flues & Chimneys - Installation and Maintenance Solutions for High-Temperature Systems

Reliable materials for flue sealing, insulation, and chimney upkeep

Vitcas offers a comprehensive selection of heat-resistant materials specifically developed for the installation, insulation, and maintenance of flues and chimneys in residential and industrial heating systems. These products are engineered to withstand high temperatures and aggressive flue gas environments, ensuring long-term durability and safety.

Understanding Chimney Systems

A chimney is the complete vertical structure designed to safely convey combustion gases from a heating appliance to the atmosphere. It typically includes:

  • Chimney breast - the visible projection into a room

  • Chimney stack - the part extending above the roofline

  • Chimney pot - a termination point for flue gases

Within the chimney lies the flue, a dedicated conduit responsible for transporting combustion gases from fireplaces, stoves, boilers, or ovens.

Types of Flues

Flues can be constructed from a variety of materials, including:

  • Flexible stainless steel flue liners

  • Clay or pumice liners

  • Concrete liners

  • Prefabricated stainless steel flues

Proper insulation and sealing of these flues is critical to maintaining thermal efficiency, reducing condensation risk, and ensuring safe discharge of combustion gases.

Vitcas Product Solutions

Vitcas supplies a range of flue and chimney support products, including:

  • Chimney & Flue Cleaner - removes soot, tar, and creosote build-up

  • Aluminium-Coated Flue Cement - seals joints and withstands thermal cycling

  • Flue Insulation Wrap - provides thermal insulation for liners and ducts

  • Heat Resistant Silicone - flexible sealant for flue pipe joints

  • Glass Fibre Lagging Rope - high-temperature wrap for sealing and insulation

These materials are suitable for both new installations and ongoing maintenance of chimney systems in wood-burning stoves, fireplaces, boilers, and outdoor ovens.
