The importance of background ventilation
In recent years, a drive to provide thermal comfort and increase
energy efficiency has seen homes becoming better sealed against
drafts than ever before.
However as homes are made more airtight, internal pollutants and
condensation can have a greater impact on indoor air quality. If
damp and pollutants cannot escape, the health of those living in a
home may be at risk.
Effective background ventilation is necessary to provide a healthy
and comfortable internal environment for the occupants of a home and
this is why trickle vents are now installed as part of window
frames.
What are Trickle ventilators?
Trickle ventilators (or trickle vents) provide background
ventilation for a home when a window is closed, contributing to a
healthy living environment by enabling unobtrusive and controllable
whole-room ventilation.
A trickle vent is situated at the top of the window frame, it allows
a small stream of fresh air to flow through from the outside into
the room and can be easily adjusted through the use of cords, rods
or simply by hand.
The benefits of installing trickle ventilators:
Cleaner air for your home
Providing effective background ventilation in your home may help to
reduce the severity of health problems such as those brought on by
respiratory ailments like asthma. It can also help to manage
background air levels of pollutants such as carbon monoxide and
carbon dioxide in your home.
Window Security
Trickle ventilators allow constant ventilation while a window is
closed and/or locked, the opening for the trickle vent is very small
typically less than 20mm wide which prevents human intrusion into
your home.
Trickle vents operate 24-hours a day
Even at night and while you are away on holiday. If a trickle vent
is left open it will provide background ventilation to your home.
While your windows are closed and locked.
Using Trickle vent to reduce noise
Trickle ventilators provide ventilation to the room without the need
to open the main window, reducing noise levels as a consequence. In
noisier locations, such as near a busy road or an airport, the
trickle vent can be designed with additional acoustic options giving
even more noise reduction benefits.
Condensation reduction
Some homes may have an existing problem with condensation,
especially in colder weather. Replacing older windows with modern
double glazed units which include a trickle vent, a suitable thermal
break in the window frame and a wide air gap between the glass panes
may improve the condensation problem, and could potentially reduce
consequent mould growth and internal surface damage.
Cost effective
Trickle ventilators are a passive home ventilation system. With the
lowest cost route for the provision of background ventilation
without the need for air bricks. Because trickle vents are passive
there are no ongoing electricity costs and they allow you to have
more control over the room ventilation than traditional air bricks.
Are trickle vents mandatory?
From December 15th 2021 trickle vents became mandatory when
replacing a window in a habitable room, bathroom or utility room. If
the existing window already has one then the new windows must offer
at least the same airflow performance as the existing trickle vent.
