The G1365 Non-Combustible Underfloor Ventilator is designed to provide a clear, unobstructed airflow passage to a void beneath an insulated suspended floor. The vent is constructed from Stainless Steel in order to be non-combustible and offer no contribution to fire. The front aperture of the duct is finished with a louvred grille slip available in a choice of 3 colours.


The evolving requirements of Part L of the Building Regulations in pursuit of energy efficiency have led to an increase in the depth of thermal insulation in suspended floors along with an increase in cavity widths to accommodate greater amounts of cavity wall insulation. This has meant that clear access to an underfloor void may require a significant vertical drop along with a large horizontal span to bridge over from the inlet point in the outer leaf.


The telescopic nature of the vent allows for vertical adjustment of between 6 to 8 brick courses and the span of the horizontal outlet is long enough to bridge through an overall wall thickness of 360mm. Both the vertical and horizontal sections of the duct can be extended using the G1361 Extension Sleeve, which adds an additional 150mm to either direction.
Due to the design, manufacture and telescopic adjustability of the products, the ducting paths are not airtight along their length there will be a limited degree of leakage both into and from the cavity void to the ducting channel.
