FENSA stance on Potential Pollution Ingress through Trickle Vents

June 16, 2025 at 11:52 am, No comments

Clause 2.3 of the FENSA regulations addresses requirements related to the installation of windows.

In general, regulations may require certain features or components to be included in window installations for safety and compliance.

One such component is a Trickle Vent

However, if there is a risk of pollutant ingress — meaning harmful substances could enter the property through these required feature

Clause 2.3 allows for the omission of these specific components is certain conditions

This exception is designed to protect building occupants from potential health risks associated with pollutants entering through window openings or vents.

Installers must assess each situation carefully and document the reasons for omitting any required features due to pollutant risks, ensuring compliance with the intent of the FENSA regulations while prioritizing occupant safety

In most cases, trickle vents will be required to be installed, however in select cases on certain elevations with - for example - very close proximity to a busy road - trickle ventilation may be bypassed
