What Are the Changes to Approved Document F?
As of June 15, 2022 in England and November 23, 2022 in Wales, replacement double glazed windows and doors must be installed with trickle vents as per the changes to Approved Document F.
What Is a Trickle Vent?
A trickle vent also known as a slot vent allows for natural circulation of fresh air continually to the room and the release of polluted air. This is generated from a small opening in Double glazed window and doors for consistant ventilation, even when closed. These vents are manufactured to enhance the air quality in a property.
Why Are Trickle Vents Necessary
In recent years, homes are better insulated and double glazing has improved, leading to less natural ventilation. This can result in the buildup of pollutants, as well as condensation and mold. Trickle vents help prevent issues associated with poor ventilation by increasing airflow throughout a home and reducing pollutants, creating a cleaner and better environment.
