Locking Band for Chimney 

Product Description

The Locking Band (or connecting clamp) is a fundamental fastening component for IZOKOMPAKT three-layer chimneys. Its primary purpose is to ensure a rigid and reliable mechanical connection between any two components of the twin-wall system (pipes, elbows, tees, etc.). Using a locking band on every joint is a mandatory condition for a safe and durable installation.

Key Features

  • Mechanical Strength of Joints: The band with its screw-tightening mechanism securely clamps the outer casings of two connected components, creating a single, rigid structure and preventing them from separating under their own weight or due to vibrations.
  • Decorative Function: It neatly and tightly covers the joint between components, giving the insulated chimney a seamless, finished, and professional look.
  • Simple and Fast Installation: The band is easily placed over the joint and tightened using common tools (a screwdriver or a wrench).
  • Durable Materials: It is made from high-quality stainless steel (AISI 430, 304L, or 316L), which guarantees high corrosion resistance and a perfect visual match with the main twin-wall chimney.

Application & IMPORTANT INSTALLATION RULES

  • MANDATORY COMPONENT: A locking band must be installed on EVERY joint between two insulated chimney components. Operating the system without locking bands is strictly prohibited.
  • Additional Fastening: To increase the reliability of the connection, it is recommended to additionally fasten the components at the joint with stainless steel rivets.
  • Requirements for Large Diameters: When installing chimneys with an outer diameter of more than 250 mm, the use of wide locking bands and additionally securing the joint with rivets (6-16 pcs. depending on the diameter) is a MANDATORY requirement.

Main Areas of Application

The locking band is a universal fastener used to secure the joints of all IZOKOMPAKT system components, for example:
