Series 1300 with Narrow Sightlines
Boyd's Series 1300 (NSL) projected-in aluminum commercial windows offer a cost-effective solution for your contemporary architectural designs. These coastal-ready systems provide versatile features for varying applications including hospitals, government buildings, military offices, universities, and schools.
To ensure the Series 1300 (NSL) projected-in windows meet CW-PG90 AAMA ratings for unforgiving coastal weather, we perform strict AAMA testing. The series is available without narrow sightlines and features dual corner-key construction—with a combination of .06" & .125" aluminum walls and a 2.375" main frame. Your Direct Assistance™ rep can also help you choose either inside- or outside-set glazing, up to 1.5" thick.
