Help CenterVELUX has improved upon the flexible tube technology used for years in the heating and air conditioning industries. Doing so, we've created a way to bend sunlight around attic obstructions to create the most cost-effective and energy-efficient skylight system available in the US.
Our Flexible Sun Tunnel® Skylight consists of a double layer of metalized polyester film with a double inner layer of reinforced aluminum Sola-film and a highly reflective, ultraviolet-proof laminate. The dome on top is made of UV-stabilized Grade-One acrylic, or polycarbonate, where debris resistance is needed.
