Are Roof Lanterns Vented?

82

When considering the installation of a roof lantern, one important aspect to think about is whether you want a lantern that offers ventilation.

A well-ventilated space not only ensures comfort but also promotes a healthier living environment. 

In this article, we’ll delve into the realm of roof lantern ventilation, exploring its functionality, benefits, types of mechanisms and address common questions too. 

Understanding roof lantern functionality 

Before going straight into ventilation specifics, it’s essential to grasp the basic functionality of roof lanterns. 

These architectural features are designed to introduce ample natural light into exterior spaces while also providing aesthetic appeal; however, their design can also affect airflow and ventilation within the enclosed area.

What are the ventilation options in roof lanterns?

Roof lanterns can be equipped with various ventilation options to regulate airflow and maintain optimal conditions indoors. 

The most common ventilation options are: 

Ridge-mounted vents

Ridge-mounted vents are one of the most popular vent options due to them being extremely effective. These vents consist of a casement-type window integrated into the roof lantern assembly. Constructed from a lightweight yet durable aluminium structure, they feature thermally broken sections to prevent heat loss and condensation. Double Q-Lon weather seals ensure optimal sealing between the vent’s lid and base, while a built-in weather bar and internal drainage system provide maximum protection from the outside elements. 

The electric operation is facilitated by a discreet chain actuated opener controlled by a wall-mounted switch. Additional features such as variable thermostatic control, rain sensor setting and manual override can be included for enhanced functionality. Manual operation via a hand pole is also available. 

Passive vents  

Passive vents are another roof lantern vent option where the vent facilitates air exchange from inside to outside only. These vents consist of operable trickle vents integrated into the roof plate, the base of the lantern. 

Equipped with a fine mesh to prevent insects from entering and an external cowl to prevent rain ingress, passive vents provide a simple yet effective means of ventilation. 

Benefits of vented roof lanterns  

Opting for lanterns that offer ventilation come with a number of benefits: 

Improved airflow

Vented roof lanterns facilitate better airflow within the room, helping to circulate fresh air and prevent stagnation. This enhanced ventilation contributes to a more comfortable living environment, especially during warmer seasons. 

Better moisture control 

Proper ventilation helps in managing moisture levels within the room. By allowing moist air to escape and fresh air to enter, vented roof lanterns mitigate the risk of condensation buildup, which can lead to mould and mildew growth. 

Odour reduction 

Effective ventilation can also help in reducing unwanted odours within the living space. By continuously exchanging indoor air with fresh outdoor air, vented roof lanterns help dissipate odours, ensuring a more pleasant environment. 

Types of ventilation mechanisms 

Roof lanterns can incorporate various mechanisms to facilitate ventilation, offering different levels of control and convenience.  

Some common types include: 

Manual vents 

These are simple openings that can be manually adjusted to control airflow. They are usually operated by hand or via a crank mechanism. Additionally, an electric opening option is also available for added convenience. 

Motorised systems 

Motorised vents are equipped with motors that automatically open and close the vents based on preset parameters such as temperature or humidity levels. Motorised vents can also be controlled via a remote control or a wall mounted control panel, depending on the model.

Integrated sensors 

Some advanced roof lanterns feature sensors that monitor indoor environmental conditions and adjust ventilation accordingly.

Overview of common ventilation mechanisms 

From simple manual vents to motorised systems and integrated sensors, roof lanterns can feature a diverse range of ventilation mechanisms. 

The choice of mechanism depends on factors such as the climate, building design and personal preferences. Understanding the available options can help you select the most suitable ventilation mechanism for your roof lantern. 

Maintenance tips for roof lantern ventilation systems 

Proper maintenance of roof lantern ventilation systems is essential to ensure optimal performance and longevity. 

Here are some practical tips to help you keep your roof lantern in top condition: 

  1. Regular cleaning 

Dirt, dust and debris can accumulate on the surfaces and components of your roof lantern ventilation system over time, obstructing airflow and reducing efficiency. Regularly clean both the interior and exterior surfaces of the lantern, including glass panels, frames and vents. 

Use a mild detergent or glass cleaner and a soft cloth to remove dirt and grime, taking care not to scratch the surface. 

  1. Lubrication of moving parts 

Moving parts such as hinges, gears and motors in motorised ventilation systems require periodic lubrication to ensure smooth operation. Apply a small amount of lubricating oil or grease to these components according to the manufacturer’s recommendations. Regular lubrication helps prevent friction and wear, extending the lifespan of the ventilation mechanism. 

  1. Inspection of damage 

Perform regular visual inspections of your roof lantern ventilation system to check for any signs of damage or wear. Look for cracks, rust, loose screws or damaged seals that could compromise the integrity of the system. Address any issues promptly to prevent further damage and maintain efficient ventilation. 

  1. Clearing obstructions 

Ensure that the ventilation openings are free from obstructions such as leaves, debris or insect nests. Periodically check and clear any blockages that could restrict airflow and hinder ventilation. Use a soft brush or compressed air to remove debris from hard-to-reach areas without causing damage to the system. 

  1. Check seals and weather stripping 

Inspect the seals and weather stripping around the perimeter of the lantern to ensure a tight seal against the elements. Replace any damaged or worn seals to prevent air leaks and water infiltration. Proper sealing helps maintain energy efficiency and prevents moisture from entering the interior space. 

  1. Test operation 

Regularly test the operation of manual and motorised ventilation mechanisms to ensure they are functioning correctly. Open and close the vents to verify smooth operation and responsiveness. Test any automatic sensors or controls to confirm they are activating as intended. 

If you notice any issues during testing, address them promptly to prevent potential malfunctions. 

  1. Professional maintenance 

Consider scheduling periodic professional maintenance and servicing for your roof lantern ventilation system. A qualified technician can inspect the system more thoroughly, identify any underlying issues and perform necessary repairs or adjustments. Professional maintenance helps prolong the lifespan of the ventilation system and ensures reliable performance over time. 

By following these maintenance tips, you can ensure that your roof lantern ventilation system remains in optimal condition, providing effective airflow and enhancing the comfort of your living space for years to come.

FAQs about vented roof lanterns 

Do you need vents in roof lanterns? 

While not mandatory, vents in roof lanterns can significantly improve airflow and indoor air quality, making them a worthwhile addition, especially in enclosed spaces. 

Do roof lanterns get condensation?

Without proper ventilation, roof lanterns can indeed experience condensation buildup, especially in humid environments; however, with adequate ventilation measures in place, roof lantern condensation can be minimised or eliminated. 

Do roof lanterns make the room cold? 

Roof lanterns themselves do not necessarily make the room cold. However, poor insulation or inadequate ventilation can lead to heat loss, potentially causing discomfort during colder months. 

Proper insulation and ventilation can help maintain comfortable indoor temperatures year-round.
