For about the cost of a nice light fixture, we can bring the soft warm light of the sun into virtually any space in your home. Installed on any roof surface in under two hours, you will quickly realize the cost benefits of a tubular skylight over incandescent and even traditional skylights. Natural Light tubular skylights do not contribute to heat loss or gain, unlike standard framed-in skylights. And did you know that electric lights can add up to 40 percent of the average heat gain in a home? As a bonus, Natural Light tubular skylights often qualify for local tax credits as an energy conservation device. Check with your local dealer or local conservation authority. Our skylight harnesses the natural light of the sun. In addition to being free, sunlight is psychologically and physiologically better for us. Sunlight offers the full visible spectrum of light which reduces eye strain, helps us to see better, makes our belongings look their true color and helps us, our pets and even plants to synthesize nutrients for healthier living. Not only are tubular skylights a better choice for day lighting, but Natural Light Tubular Skylights are one of the best in their class with high standards for quality and functionality. Our 25 year product warranty is the best in the industry!
