The IL Adjustable Length 305mm (12in) - Ø 125 is part of a well-regarded twin wall insulated pre-fabricated gas vent system that's been a staple in the UK for over 25 years. Designed specifically for naturally aspirated domestic gas-fired appliances, this vent system is ideal for applications requiring a draught hood or diverter. It operates under negative pressure and dry conditions, withstanding flue gas temperatures up to 250°C.
Available in three key diameters—100mm, 125mm, and 150mm—this vent consists of an aluminium liner encased in a zalutite outer shell, separated by a 6mm air gap for added insulation. Suitable for both internal and external installations, it excels in non-condensing and negative pressure environments.
