How Much Light Does a Roof Lantern Add?
Roof lanterns have become a very popular way to add natural light to many homes, particularly in kitchens, extensions, or open plan living rooms. Many homeowners often wonder just how much light a roof lantern can add. The answer depends on a few factors including design, size and glazing, but even smaller roof lanterns can help brighten a room.
The Basics of Roof Lanterns
The roof lantern is essentially a glazed window structure installed on top of a pitched or flat roof. It sits high above the room, bringing in light from above rather than through windows alone. Unlike skylights, roof lanterns are much larger and multi-faceted, providing both a sense of space and natural light.
Size Matters
The amount of light from a roof lantern is linked to its size:
- Larger lanterns allow much more sunlight to enter, creating a bright room.
- Small lanterns still provide improvement for rooms without overhead glazing.
As a general rule, a lantern should at least cover up to 15% of the floor area to have a significant impact on providing natural light.
Design and Shape
The shape and design of a roof lantern also influence how light spreads:
- Multi-faceted or pyramidal style lanterns distribute light across the room.
- Rectangular lanterns or flat are ideal for narrow spaces.
- Pitch and height: Higher lanterns allow for more light to penetrate, helping to reduce shadows.
A well designed roof lantern maximise natural light while maintaining energy efficiency and style.
Glazing Options
Glazing plays an important role in both thermal performance and the amount of light:
- Clear glass provides the maximum natural light, however it can increase heat during the summer months.
- Solar control glass or Low-E glass helps balance light with energy efficiency.
- Patterned glass and tinted glass also help to reduce glare, whilst still admitting daylight.
Choosing the correct glass ensures a room benefits from light without unwanted glare or heat.
Effect on Room Atmosphere
Roof lanterns help to transform interiors in several different ways:
- Brightens dark spaces that vertical windows can’t do alone.
- Makes rooms feel more open and larger.
- Enhances visual appeal of the property.
- Can reduce the need for lighting systems during the day time.
Even the smallest of roof lanterns can make a difference, improving the functionality of space.
Positioning Considerations
Where the lantern roof is placed can affect the light provided:
- Central lantern roofs distribute light evenly.
- Alignment with key living areas such as kitchen, dining table maximises benefits.
- Avoid obstructions from nearby trees and overhanging eaves to ensure maximum sunight.
Proper placement of Lantern roof is essential to get the most out of the daylight.
Conclusion
A roof lantern can provide a substantial amount of light to any room. Its impact depends on the type of design, glazing, size and positioning. Even small lantern roofs can bright up interiors, reduce reliance on lighting and enhance atmosphere. For homeowners looking for open, bright and inviting living space, a roof lantern is a stylish and practical solution.
