The IL Firestop Spacer - Ø 125mm is an essential component in the realm of domestic gas ventilation systems. Over the last 25 years, this twin wall insulated pre-fabricated gas vent system has earned a stellar reputation for its quality and reliability. Engineered specifically for naturally aspirated domestic gas-fired appliances equipped with a draught hood or diverter, this spacer ensures the chimney operates under negative pressure and dry conditions.
Designed to handle flue gas temperatures up to 250°C, this product boasts an aluminium liner and a zalutite outer case, separated by an efficient 6mm air gap. Available in three distinct sizes - 100mm, 125mm, and 150mm - it is suitable for both internal and external applications, though not for condensing and positive pressure systems. It seamlessly integrates with support plates to maintain the appropriate clearance to combustible materials, making it a versatile and reliable choice for any gas vent system.
