One of the brightest solutions around
Solatube is recognised as being one of the most efficient tubular daylighting systems on the market. This is because:
- · The Solatube uses a new, redesigned dome on the roof, rather than a flat collector, which is able to gather more ambient light from all around, as it is not dependent on light shining directly down it.
Redesigned specifically for Northern Europe and also to help counter spurious claims, the new Solatube dome now delivers more light than ever before, eclipsing the competition and ensuring that Solatube remains the world’s brightest sun tunnel system.
- · 99.7% reflective tube lining in a Solatube is the most reflective material used in tubular daylighting devices. It ensures that the most light is delivered in to the room.
Thanks to Solatubes intelligent design you may need to install a larger diameter system, or a greater number of systems, from other manufacturers in order to deliver the same amount of light.
So, please don’t fall for misleading information:
I. Contrary to some statements, competitor systems CANNOT claim to deliver 70% more light than the latest Solatube. Currently no manufacturer has up to date comparative test data from the BRE using the new dome; all claims against Solatube are based on old and out of date systems using a dome design that has not been used for over a year.
II. Comparisons by certain competitors actually use a larger diameter tube to test and compare their performance against the smaller Solatube. And of course a larger 380mm dia tube will deliver more light than a narrower 335mm dia Solatube, but it’s hardly a fair, reasonable or scientific comparison.
Brighter than roof and sky lights
Conventional roof or sky lights normally need an associated plasterboard light well beneath them to funnel light in to the room below. Consequently they are unable to deliver as much light as a highly reflective Solatube, which is designed to pipe daylight down to just where you want it.
- Light wells tend to create a shaft of light leaving a brightly lit square of light, rather than well spread and evenly diffused daylight throughout the room.
- Light wells are a haven for cobwebs and spiders and will require frequent cleaning.
- The thermal efficiency of a larger roof window and light well is poor compared to a smaller Solatube. In winter you effectively have a large hole in your ceiling where heat will escape, whereas a Solatube will deliver the same amount of light but through a far smaller aperture which is sealed at ceiling height.
- In summer you are also likely to suffer from solar gain (heat build up), which the well insulated Solatube prevents.
- Condensation is likely to be an issue with roof lights, whereas a Solatube dissipates any condensation that may form, out on to the roof.
- Keeping roof windows clean can be difficult and time consuming – both inside and out, due to access and attendant safety issues. Solatubes require no cleaning or maintenance.
- When it rains, roof windows can transmit a loud drumming noise in to the room below, which a Solatube does not.
- If security is a consideration then the smaller size of a Solatube means they do not form an easy access point and also it is not possible to see through a Solatube.
