Glass and Acrylic Blocks

Hy-Lite Block Windows combine the beauty of glass block with the quick and easy installation of a standard window. Constructed of lightweight acrylic blocks, Hy-Lite windows are fully prefabricated and glazed units. Because there's no mortar, there's no mess, no delays, and no headaches.

Ships and Installs Easily as a Complete Window: All of our windows--aluminum framed, vinyl framed, and operable vinyl framed windows--arrive as completely prefabricated and glazed units. No assembly required. All Hy-Lite new construction windows come with attached nailing fins for easy standard installation.
Ten Year Limited Warranty: With millions of blocks installed throughout every region of the country, Hy-Lite has the confidence to offer a Ten Year Limited Warranty. This warranty guarantees your window won't leak and the blocks won't yellow. To further prove the quality of our windows, we have the results of numerous industry tests to prove it .
75% Lighter than Glass Block: Acrylic blocks make for a lighter block window. No extra reinforcement is necessary, so you can have the beauty of glass block in places where heavy glass is not practical. Also, you won't encounter sagging or cracking of blocks, over time.
35%-40% More Energy Efficient than Glass Block: As heating and cooling costs increase, homeowners are becoming concerned about the thermal efficiency of all building products. Hy-Lite answers those concerns by offering both vinyl framed and thermally broken aluminum framed windows.
Safety Glazing Approved: Hy-Lite windows are perfect above bathtubs and as shower walls. And because they are safety glazing approved, they are not only safe, but are accepted by most building codes.
High Quality Acrylic: Hy-Lite uses the highest quality acrylic for its blocks. This acrylic won't yellow and resists scratching. In fact, they use the same high quality resin used for all automobile tail light lenses, so exterior weathering and durability is excellent.
Airtight Sealed Blocks: Every Hy-Lite block--including their patented triangle block--is sealed to prevent internal condensation.
