Window World’s patio doors, also known as sliding glass doors, are crafted with durability and ease of use in mind. A door that sees as much use as your sliding glass door definitely needs attention to detail, and that critical eye is shown in each element of ours. Let’s take a closer look at each element of Window World’s patio doors, so you can see the level of craftsmanship that goes into every detail.
Anatomy of a Window World Patio Door
Mainframe
The mainframe is the outermost portion of the window. This surrounds the rest of the window, giving it the support it needs to stand strong to the elements. Window World uses premium vinyl for our frames, which is durable and means you’ll never have to worry about painting or repainting your windows.
Double-Wall Design
Like all our mostly-glass doors and windows, we use a double-wall design for the glass in our patio doors for increased energy efficiency and to provide more strength to the design. Double-wall glass keeps the cold air out in the winter and in during the summer, so you’ll be comfortable year-round — and save on your energy bills as a bonus.
Dual Weatherstripping
Weatherstripping on our doors’ sashes provides plenty of thermal insulation, meaning your home will stay comfortable with the heat or cool air from the outdoors staying out. Plus, with dual weatherstripping, you’ll get double the insulation power.
Durable Rails
The rail is the horizontal surrounding edge connected to the sash of our patio doors. Our symmetrical 3” rails provide a sleek edge with mitered and fusion-welded joints for enhanced style and sturdiness.
Insulated, Energy-Efficient Glass
Our 1”-thick insulated glass package includes the Intercept® Warm-Edge Spacer System for additional energy efficiency. The Intercept® Warm-Edge Spacer System provides insulation for the exterior edges of the sealed glass, giving you up to an additional 5% off your energy bills. Our glass units are filled with argon gas, a colorless, harmless gas sealed between the double panes of our patio doors. It increases insulation due to being less heat-conductive than air.
Reinforced Interlocks and Lock Rails
Our steel-reinforced interlocks and lock rails provide a heavy-duty durability meant to increase the structural integrity of the door. Interlocks are a set of meeting rails which allow the rails to physically engage with each other over the full length of the rails. This is how the patio door can slide easily without hitting the other rail.
Precision-Engineered Rolling System
As a sliding door, it is integral to its structure that our patio door can smoothly glide open and closed. That’s why we use a strong tandem rolling system. This allows for quiet, frictionless door movement, and an unobstructed enjoyment of the outdoors for your home.
Mainframe Joints with Superior Sealing
Our mainframe joints are the outermost corners of the patio doors, where the mainframe corners meet. These are sealed with closed-cell foam gaskets, which provide a strong initial thermal protection. This water-resistant material keeps precipitation out and your home’s heating or AC in.
