What is a Heliobus Mirror Shaft Mirror Shaft)?
A Heliobus Mirror Shaft an architectural daylighting system that directs natural light into basements, ground-level basements, and cellar areas via a mirrored module. It is integrated into an existing light well and replaces the grating with a walkable glass cover, allowing more natural light to enter and creating a significantly more pleasant indoor atmosphere. Unlike a conventional light well, the light is not merely “admitted” but is actively guided and made more usable.
How much does a Mirror Shaft cost, Mirror Shaft ?
A Mirror Shaft typically Mirror Shaft between approximately 5,000 and 8,000 CHF, including installation. The exact price depends on the dimensions, installation conditions, location, design, and options.
What are the advantages of a mirrored light well compared to a conventional light well?
A Mirror Shaft significantly Mirror Shaft the use of natural light in the basement because the light is actively directed via mirrored surfaces. This makes rooms appear brighter and more attractive, often resulting in a noticeable improvement in the quality of the space. In addition, the forecourt area is usually preserved because no additional excavation is required, as is the case with large light wells. In many cases, this also creates a better sense of space, as the room feels less “confined” and the view to the outside is enhanced.
Does the Mirror Shaft work Mirror Shaft when the sky is overcast?
Yes, because the Mirror Shaft makes use of diffuse sky light. In direct sunlight, the light output is generally higher, but even in rain or cloudy conditions, the room can be visibly brightened, provided the light well receives enough daylight.
Will ventilation of the basement still be ensured after installation?
Yes, ventilation is generally still possible because the glass cover is designed to allow air to circulate through built-in ventilation openings. As a result, the light well continues to function as a ventilation pathway in many cases.
Can water get into the shaft when it rains?
Yes, when it rains, water can enter the shaft through ventilation openings, similar to many light well solutions. It is crucial that the bottom of the shaft is designed for drainage so that water can drain away reliably.
How often does the Mirror Shaft need to be Mirror Shaft ?
In many cases, cleaning once or twice a year is sufficient. If there is a lot of dirt from leaves, dust, or construction debris, more frequent cleaning may be advisable.
Will I still be able to fit into the light well after installation?
Yes, depending on the design, access may still be possible—for example, through the window and movable elements in the system. If access is essential for maintenance or as an escape route, this should be explicitly taken into account during the planning phase.
Why does condensation form in the Mirror Shaft?
Condensation forms when moist air comes into contact with a cold surface and the temperature drops below the dew point. This can occur especially during transitional seasons (spring/fall), when temperatures drop suddenly, or during heavy rain, because glass and metal surfaces cool down quickly under these conditions.
How can condensation be prevented?
Heated laminated safety glass is a very effective option because it raises the surface temperature, thereby reducing condensation. In addition, proper drainage, the correct slope, and a functioning drain help prevent moisture from pooling.
Is the Mirror Shaft —can you walk on it or place furniture on it?
Yes, the glass cover is designed to be walkable, so it can be walked on in everyday use. For high-traffic areas or when the surface is wet, a slip-resistant finish is recommended because it significantly improves safety.
Is the Mirror Shaft against break-ins?
The Mirror Shaft enhance burglary resistance because the shaft is securely sealed at the top. Additionally, depending on the model, burglar-resistant options or additional security features can be selected.
