Trickle Vents

What are Trickle vents?
Trickle vents are an essential component of modern buildings’ ventilation systems. Trickle vents are small adjustable openings that are strategically integrated into windows and doors to promote maximum controlled airflow between the interior and exterior of a building. They are typically positioned in the sash or the frame. Trickle vents allow a continuous ‘trickle’ of fresh air into the building, this exchange of fresh air helps to remove excess moisture and condensation along with pollutants and odours from the interior of a building, creating a healthier environment.

What are the benefits of Trickle vents?
Continuous ventilation, Moisture control and Air Quality. Trickle vents allow a steady flow of fresh air to circulate, this continuous ventilation improves the air quality, which is essential for maintaining good health, by removing stale air and minimizing indoor pollutants and excess moisture. Excess moisture in your property can lead to mould growth and health risks that are associated with poor air quality.

Security Benefits.
Trickle vents allow you to create airflow without having to leave windows wide open, making your property more secure.
