Twin Wall Flue Systems

A twin wall flue system is a clever chimney system that safely and efficiently vents flue gases from wood burning stoves and condensing boilers. It has two concentric walls with insulation sandwiched in between. The inner wall is usually stainless steel or vitreous enamel and is designed to be durable and heat resistant. The outer wall is usually stainless steel or aluminum and adds extra protection and strength. The insulation in between the walls is what minimises heat loss and makes the system more efficient. Twin wall flue systems are designed to be a reliable venting solution for flue gases so are perfect for all types of heating appliances.

Twin wall flue systems have many benefits over traditional chimney systems. One of the biggest is their flexibility and ease of installation. These can be installed through walls, floors and roofs, so they are perfect for existing buildings where a traditional chimney stack may not be possible. Twin wall flue systems are also more efficient and safer, reducing heat loss and flue gas leaks. They’re also aesthetically versatile and can be finished in various colours and finishes to match the surrounding architecture. All this functionality and style makes twin wall flue systems the perfect choice for modern heating.
