Trickle Vent - Capral

Capral Trickle Vents – a natural ventilation solution for healthy and energy-efficient homes.

With the advancements in building standards, and the drive to improve thermal comfort and energy efficiency, today’s buildings have become more airtight with less air leakage. This contributes to poor indoor air quality where dust mites, moulds, viruses, bacteria and chemical substances can accumulate, impacting on the health of a home’s occupants.

Of course, we can open windows and doors to allow fresh air in, however this is often a temporary solution that can compromise energy efficiency, security and comfort. The need for regular ventilation thus becomes an important consideration in the maintenance of indoor air quality. Trickle vents have been designed as an effective ventilation solution. Without the need of electric power, sensors or human interaction, trickle vents passively control ventilation. 

The advantages of Capral's Trickle vents:
Consistent supply of ventilation even when windows are closed, especially at night or when the home is unoccupied.
More secure than an open window where you can be vulnerable to burglary, annoying insects and noise.
Helps control air moisture that can lead to mould and mildew.
Installed above window frames means views are unobstructed.
Safer for children.
