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



Hy-Lite®, a U.S. Block Windows Company, is proud to be the leading manufacturer of privacy windows in the United States. Hy-Lite offers a wide selection of customized, pre-framed acrylic block windows, glass block windows and decorative glass windows. Unique, stylish, and made with pride in the U.S.A., these dazzling privacy window products are more than just windows... They're jewelry for your home!


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.

All Hy-Lite® acrylic blocks are injection-molded from American-made resin in our Pensacola, Florida manufacturing facility. Our acrylic block window products are proudly made in the U.S.A. by American workers from start to finish. Each Hy-Lite product is custom made to the specifications of the customer.
