Buy Duplus SunTube Online

The new Duplus SunTube draws on One Bounce® technology and adds another dimension to tubular skylights. The addition of the Intech lens optimises the through-put of light from dawn to dusk.

Until now, tubular skylights have only performed at their optimum level when the sun is high in the sky (from 10.00am to 2.00pm). In most instances, tubular skylight performance decreases dramatically in the early morning and late afternoon when needed most. The Intech lens collects the low elevation sunlight in the early morning, late afternoon and winter, whilst at the same time regulating the light during the hot midday summer sun to provide cooler daylight.

The use of our patented Variable Pitch Adaptor enables us to provide a straight path of light between any roof pitch and ceiling, and to bypass obstacles without having to bend our tube around them. To this day, copycat products resort to the use of light reducing angle adaptors (elbows) or low performing flexible ducting to avoid obstacles.
