Timber Roof Lantern Ventilation
Ventilation can be incorporated into our timber roof lanterns to improve airflow and help regulate temperatures within the room below. Depending on the lantern design and configuration, options include ridge-mounted opening ventilators for more substantial airflow or trickle vents for continuous passive ventilation.
Ridge-mounted ventilators can be manually or electrically operated where suitable, while passive ventilation provides a discreet solution for lantern designs where an opening ventilator is not appropriate.
Ridge mounted roof ventilators
A highly effective and popular method for optimizing ventilation in a roof lantern is the inclusion of a ridge-mounted casement-style window. This vent is constructed with a high-performance aluminium frame, which combines lightweight properties with exceptional strength. The use of thermally broken sections minimizes heat loss and prevents condensation, ensuring excellent energy efficiency.
Double Q-Lon weather seals between the vent’s lid and base provide superior airtightness, while a built-in weather bar and internal drainage system offer robust protection against external elements like rain and wind. For ease of use, the vent can be electrically operated via a discreet chain actuator connected to a wall-mounted switch. Additionally, the electric operation can be upgraded to include variable thermostatic control, a rain sensor for automatic closure during wet conditions, and a manual override for personalized control. Electrical installation is typically handled by a qualified electrician.
For those who prefer manual control, the vent can also be operated using a hand pole, offering a practical alternative to electric operation.
Not available on The Markham and Egerton roof lanterns in the Classic Collection nor any roof lanterns in the Linear Collection.
Passive ventilators
Passive ventilation refers to the natural flow of air between the interior and exterior of a space without the need for mechanical systems, facilitating a steady exchange that helps regulate indoor air quality and temperature. This process is particularly beneficial in preventing the build-up of moisture, reducing the risk of condensation, and maintaining a comfortable indoor environment.
In roof lanterns, passive ventilation is achieved through the installation of operable trickle vents, which are built seamlessly into the roof plate—the structural base of the lantern. These vents can be opened or closed manually, allowing users to control the airflow based on their comfort needs. The system also includes fine mesh screens that act as a barrier, keeping insects from entering the space. Additionally, an external cowl is fitted to prevent rainwater from seeping in, ensuring that the interior remains dry even during inclement weather. Together, these elements create an effective and low-maintenance solution for natural ventilation, enhancing the functionality of your roof lantern while maintaining its sleek aesthetic.
