The Company

Starmark Evo Windows is a product developed by HiMark Windows LLC dba OKNA Windows and is produced in a 220,000 sq. ft. state-of-the-art manufacturing facility in Bristol, Pennsylvania USA.  Combining advanced technology and dedicated craftsmanship, the name has become synonymous with innovation, quality, and performance.  Advanced automated equipment and computer-controlled production lines ensure a high standard of quality control as well as the ability to meet large volume requirements quickly.

Since its inception in 1994, OKNA Windows continues to grow and redefine their commitment to satisfaction and the evolution of their products. Having already made a mark on the industry, the company wanted to offer something beyond vinyl.  The Starmark window was first introduced in 2004.  The Starmark Evo is the series third-generation version, and uses advanced polymeric composite (APC) material.  Product improvements and steady growth make Starmark Evo Windows major player on the East Coast with products designed to meet the needs of a wide range of clients.

Offering full Replacement and New Construction windows, the entire production line can be customized in a variety of ways with a paint facility on the premises, to make sure the products are the top choice in residential construction.

All products are tested in independent testing facilities and meet or exceed the most rigorous Energy Star, AAMA, and NFRC certifications. As a result, STARMARK EVO delivers absolute performance backed by an outstanding warranty. There is no better way to demonstrate commitment and confidence!
