Sun Valley has a wide selection of aluminum I-beam and tubular sections for skylights, solariums & conservatories.  Through innovative design & assembly techniques, we can eliminate exposed hardware in most cases. This enables us to provide you with very large and complex structures, without a single visible bolt or unfinished weld.

A mechanically articulated building element lends itself to opening up interior spaces and can bring a unique design element to a project.  To that end, Sun Valley provides customized Retractable Skylight Systems, monumental Pivoting Windows, Exterior Barn Door Sliders and Folding doors.


Sun Valley offers Fleetwood Windows & Doors.  We are able to provide custom applications using Fleetwood products or alternatives when Fleetwood cannot provide the full scope of work.  We can provide product only or a professional installation. All packages are sold with in-house or generic shop drawings & field measurements.

Our knowledge of complex assemblies enables us to construct and provide custom design solutions.  Some of the products that we have been asked to design are decorative aluminum louvers, chimney caps, canopies, custom metal cladding and a host of other products.

Who We Are

Our goal is to design and install products that deliver a lifetime of superior performance.

“I wanted to take a moment to tell you about my work experience with Sun Valley on a recently completed window project. This was the first time that we have worked with them and this project had a very demanding architect. I am pleased to say that Sun Valley came through in an exceptionally professional manner. David Witty was very gracious through the numerous changes, requests for design input, etc. The final product was delivered on time, on budget with a beautiful result.”
