Patio Doors That Reduce Heat Transfer in Florida’s Climate

What Florida's Climate Does To Patio Doors

In Florida, a patio door is dealing with heat, humidity, glare, and storm exposure all at once. The glass sits in direct sun for long stretches, the frame bakes in outdoor temperatures, and the seal between inside and outside is under constant pressure.
