Will the Sun Tunnel help with the winter 'blahs'?

Winter time means that lots of us get stuck indoors at home and work. Studies show that natural, full-spectrum sunlight greatly contributes to increased productivity in the workplace and to an overall feeling of well-being.

By bringing the sun into your house, or home office, a Sun Tunnel can help you beat the winter blahs.

Can you help me understand more advantages of installing a flexible Sun Tunnel?

One of the key components in The Sun Tunnel system is its flexible, reflective tunnel. This tunnel is similar in structural design to the tubing used for many decades in the heating and air conditioning industry and can be found in commercial businesses, high-rise buildings, hospitals, schools, and residential homes throughout North America and many other parts of the world.
Sun Tunnel has taken this time-proven technology used by air conditioning and heating contractors to provide comfortable living, and added a space-age U.V.-proof liner to the inside in order to channel sunlight efficiently through attics to dark rooms all over the world. The clear dome on the roof is made from U.V. resistant materials, nearly eliminating harmful U.V. rays before they can even reach the tunnel, which guarantees that the flexible tunnel will perform for many years to come.

The ability to flex around almost any attic obstruction without the need for elbows or extensions means that Sun Tunnels can be efficiently and economically installed in places no other tubular product can reach. Naturally, the shorter, tighter and straighter you install the tunnel, the better the performance, but Sun Tunnels are installed every week in hard-to-reach areas, sometimes with 90-degree bends in the tunnel, and are still performing well.

The 22" diameter Sun Tunnel is the largest on the market today and will brighten even the largest rooms in your home. Just like the tunnel used in our other models, our 22" flexible tunnel passes all ignition, flammability and smoke density testing requirements necessary to meet National Building Codes standards across the United States.
