Acrylic block windows by Hy-Lite Products

Backed by a 10-year warranty, the durable frames come in either vinyl or aluminum and feature a streamlined design. The aluminum frame is thermally broken for increased thermal performance and comes with snap-off nail fins. An optional 1 3⁄4-inch aluminum frame has no nail fin and can be used for sidelites, doorlites and transoms. The frames are available in painted white, tan, bronze and clear anodized.
