Series 4400 Project Out

Boyd's Series 4400 (PO) aluminum casement windows feature dual corner-key construction and true, interior, and historical muntins for easier maintenance. The series is available with AW-100 AAMA ratings, making our casement projection windows the smart option for coastal applications.

These versatile systems are perfect for schools, universities, hospitals, government offices, military buildings, and other monumental applications. Before they can meet Boyd standards, our engineers run strict AAMA tests on our Series 4400 aluminum casement windows. Only then is your Direct Assistance™ rep satisfied that crucial features will exceed your expectations: a 4" deep main frame, a combination of .062" and .125" walls, and your choice of inside- or outside-set glazing—up to 1.5" thick.
