Hy-Lite Products offers low-profile frame options for a variety of its acrylic block windows. The durable frames come in either vinyl or aluminum and feature a streamlined design. The aluminum frame adds just 1 in. on all sides of the unit while the low-profile fixed vinyl frame adds 2-in. of visible frame materials. Constructed with 2-in. thick acrylic blocks, windows with the low-profile fixed vinyl frame include a 7/8-in. nail fin offset and interior and exterior accessory pockets. The vinyl frames are fusion-welded for maximum strength. They are available in white or tan.
