What Are Velux Sun Tunnels?

Velux Sun Tunnels, also known as tubular skylights, are designed to bring natural light into dark areas of your home where traditional skylights are not feasible. They consist of a roof-mounted dome that captures sunlight, a highly reflective tunnel that channels the light, and a ceiling-mounted diffuser that spreads the light throughout the room. These sun tunnels are particularly useful in spaces like hallways, bathrooms, closets, and kitchens.

Types of Velux Sun Tunnels

Velux offers two main types of sun tunnels:

Rigid Sun Tunnels: These provide a straight, unobstructed path from the roof to the ceiling, offering the brightest light output. They are ideal for long runs and for areas where the tunnel can remain straight.

Flexible Sun Tunnels: These are suitable for shorter runs and for installations where there are obstacles in the attic. They can bend around obstructions, making them versatile for various home layouts.

Cost of Installing Velux Sun Tunnels

The cost of installing Velux Sun Tunnels can vary based on several factors:

Type of Sun Tunnel: Rigid tunnels typically cost more than flexible ones due to their brighter light output and the complexity of installation.

Size of the Tunnel: Velux sun tunnels come in 10-inch and 14-inch diameters. The 14-inch tunnels are more expensive but provide twice the amount of light compared to the 10-inch ones.

Length of the Tunnel: The cost increases with the length of the tunnel. Standard installations cover up to six feet of tunnel length, with additional extensions costing extra.

Installation Complexity: Factors such as roof type, attic space, and the presence of obstacles can affect installation difficulty and cost.


On average, the cost to install a 14-inch Velux Sun Tunnel ranges from $1,100 to $1,400, including labor and materials for a standard installation up to six feet. Additional extensions typically cost around $90 each. For a 10-inch sun tunnel, you can expect to pay about $100 less.

Benefits of Installing Velux Sun Tunnels

Energy Efficiency: Sun tunnels reduce the need for artificial lighting, thereby saving on electricity bills.

Improved Natural Lighting: They bring natural light into dark spaces, making rooms feel larger and more inviting.

Quick Installation: Most installations can be completed in a few hours, minimizing disruption to your home.

Durability: Velux sun tunnels come with a 20-year warranty on the reflective tubing, ensuring long-term performance.

Additional Considerations

Federal Tax Credit: Certain models of Velux sun tunnels with solar night lights are eligible for a 30% federal tax credit, which can significantly offset the installation costs.

Professional Installation: While it is possible to install sun tunnels yourself, professional installation is recommended to ensure proper sealing and prevent leaks. Professional installers have the necessary experience and equipment to safely and efficiently complete the job.

Finding a Professional Installer in Knoxville

If you’re ready to brighten your home with Velux Sun Tunnels, it’s important to find a reputable installer in Knoxville. Look for certified Velux installers who can provide a detailed quote and ensure a high-quality installation. Getting multiple quotes from different contractors can help you compare prices and services, ensuring you get the best value for your investment.

Installing Velux Sun Tunnels in Knoxville, TN, is a cost-effective way to enhance the natural light in your home while reducing energy costs. With a variety of options and professional sun tunnel installers available, you can easily transform dark, unused spaces into bright, welcoming areas.
