Hy-lite Acrylic & Glass Block

Our History

Established in 1988, Hy-Lite Products revolutionized the privacy window market by introducing pre-framed acrylic block windows as an alternative to old-fashioned glass block. Lighter and easier to install than traditional glass block, Hy-Lite’s acrylic block windows eliminated the mortar, mess, and time-consuming labor of old-fashioned glass block masonry window applications.

In 1996, U S Block Windows, Inc. was founded, further modernizing the privacy window market by introducing impact-modified acrylic blocks as well as cut-to-size and fully operable acrylic block windows. Winning a Crystal Achievement Award in 2001 for its revolutionary acrylic block single hung and acrylic block slider, U S Block Windows, Inc. proudly led the block window market into the 21st century with its many unique patents and groundbreaking innovation.

On March 30, 2009, U S Block Windows, Inc. acquired the assets of Hy-Lite Products and now proudly manufactures the nation’s most robust line of privacy window products as

Hy-Lite®, a U.S. Block Windows Company.
