Product Description

The Double-Wall Sleeve, crafted from 0.8 mm black steel, is a component for the safe connection of a single-wall pipe to a brick or ceramic chimney stack. It is a part that is installed into the chimney wall to form a protective and connecting port. Unlike single-wall versions, this sleeve features a double-wall construction with an air gap. This provides additional thermal insulation, reduces the temperature of the outer surface, and protects the chimney walls from high temperatures and cracking.

Key Features

• Thermal Insulation and Safety: The double-wall design creates an air gap that acts as an insulator. This significantly reduces the temperature on the outer surface of the sleeve, increasing the fire safety of the connection point.
• Chimney Stack Protection: Prevents direct exposure of the masonry or ceramic liner to high temperatures and thermal shock, protecting it from cracks and premature deterioration.
• Durable Connection: Creates a robust and stable port for connecting steel pipes, simplifying their future maintenance or replacement.
• European Quality and Safety: The product is certified and CE marked, confirming its full compliance with the European standard for flue systems EN 1856-2.

Available Diameters and Specifications

Important Limitations

• For Solid Fuel Appliances: Intended for use with wood-burning stoves, fireplaces, and solid-fuel boilers.
• Requires Professional Installation: The sleeve must be installed into the chimney wall using appropriate heat-resistant mortar or sealant.
