The program runs fourteen stocked sizes from 24 in. to 72 in. wide in 10, 12, and 16 in. heights, in White and Black frames. Glazing is double strength clear glass in a double pane insulated unit with argon fill, rated at a 0.31 U factor and 0.25 solar heat gain coefficient with Florida product approval in the flagship size, and the DP50 design pressure rating is stated across the program. The integrated J channel ties the frame directly into vinyl siding for a clean surface mounted install, and the overall frame runs about 1.5 in. larger than the listed size in each direction.
