Quality Home Improvements Since 1947  It's hard to believe that it's been 60 years! C-Thru Sunrooms is a family owned and opeated company. We are licensed and insured. We have been in business since 1947 and have hundreds of thousands of satisfied customers. Over the years, our rooms have constantly been improved by incorporating the latest manufacturing, construction, and energy-efficiency technologies.     C-Thru's state of the art manufacturing facility in Riverside, CA C-Thru Industries, Inc. was founded by Stanley J. Albany in 1947 as the C-Thru Aluminum Awning Company. One of his basic business philosophies was "Our customers deserve a quality product at a price they can afford." C-Thru has led the pioneering effort in producing such items as the structural aluminum patio cover, the patio room enclosure, safe integrated electrical raceway systems, and the finest sunroom in the industry. Mr. Albany passed on his belief in business integrity, and a legacy of "quality without compromise" to his two sons in December 1988. Kirk and Jason Albany are carrying on his heritage by maintaining the same high standards. C-Thru Industries has established itself as a world-class manufacturer of sunrooms, conservatories, and patio enclosures. Almost 60 years of experience have led to a product that is beautiful, durable, and second to none. In this process, C-Thru has produced a product that is superior in many ways to a conventional home addition, while elevating the standards to which all sunrooms are produced.
