Skylights & Suntunnels


Heyn Brothers is a 3-Star Velux installer. We have had training from the manufacturer on proper installation ensuring that we can eliminate problems that could come up from improper install. We are able to order an almost endless size range to match existing skylight openings or make custom fits for skylights. Our most popular options available are the Sun Tunnels available in three sizes to accommodate most room sizes. Sun Tunnels are a great addition to hallways, closets, bathrooms, and other areas that no windows are available. These are also very popular for townhomes that have adjoining walls and less natural light. With more than 90% of Velux production ENERGY STAR® qualified in all United States climate zones, you can include our products confidently and proudly.
