Sun Tubes

Installing a Sun Tube Skylight

Suntrenz sun tubes are designed to provide an eco-friendly and cost-effective way to brighten up any space with natural daylight, reducing the need for artificial lighting and saving on energy bills.

Our sun tubes are made from premium materials that are built to last, ensuring durability and longevity. With our state-of-the-art design, our sun tubes capture sunlight from your roof and transport it through a highly reflective tube, bringing sunlight to even the darkest corners of your home or office.

Whether it’s a gloomy hallway, a dim basement, or a poorly lit bathroom, installing a Suntrenz sun tube will flood your space with natural light, creating a warm and inviting atmosphere. Find ideas for bathroom installations and hallway installations in our articles.

How Does a Sun Tube Skylight Work

Sunlight enters the sun tube dome. The UV stabilized, high impact, acrylic dome has a very high light transmittance allowing more of light to enter into the tube.

Sunlight is reflected through the sun tube’s mirror-like tube. The sunlight then reflects down a highly reflective mirror like tube, connecting the roof to the ceiling.

The high reflection of the tube means the performance is still very efficient, even during times when available sunlight is reduced such as early morning, late afternoon and during overcast conditions.

The sun tube diffuser then evenly disperses the sunlight into the building. The sunlight that has reflected down the tube then passes through two layers of textured acrylic, which have been specifically designed to spread the light evenly around the room. These diffusers also have a very high light transmittance allowing more of light to pass through them.

It also has the dome at roof level, reducing heat transmittance, and none of the tubing components hold heat. Therefore, there will be no additional heat load on the building. In fact, compared to electrical lighting, or traditional skylights, the temperatures are significantly lower.
