Vertical Sliding Windows

Vertical Sliding Windows

We offer vertical sliding windows in San Diego. Our quality fiberglass vertical windows are able to open from top-to-bottom or bottom-to-top. The choice is yours!

The way your home looks presents the ultimate statement of who you are as a person, so choosing the windows that best fit your needs is an essential decision. The right windows can drastically improve the overall appeal of your San Diego home or office, and raise the market value, curb appeal and even offer significant savings with improved energy efficiency. As today’s market has unlimited options to choose from, finding the windows that are right for you can be somewhat difficult.

Celebrated for their simple and elegant design, vertical sliding windows have been a common choice for centuries, from the Georgian era to the present day. They’re the most common choice in a wide variety of homes and because of their timeless beauty that goes well with different architectural styles. Vertical sliding windows consist of two sashes in a single frame. There are two types of vertical sliding windows, the single-hung and the double-hung window. The single-hung window, often referred to as a sash window, has the top sash fixed, while the bottom sash can be opened. On a double-hung window, both top and bottom sashes can slide up or down.

Many people prefer vertical sliding windows over other types since they’re easy to operate. They can be used in many different scenarios to make your San Diego home more comfortable and enhance its appeal at the same time. If you’re looking to give your home a classic look with a modern twist, vertical sliding windows are a great choice. They work well in almost any room and can be paired with other window types for interesting and exciting combinations.


Vertical sliding windows offer a few significant benefits over other types of windows. Since they open and close without protruding, they don’t require any extra space for operation. This makes vertical sliding windows shine in areas with limited available space and make them a perfect choice for walkways, porches or patios. They’re also a great option for areas that need to be ventilated quickly, like kitchens, bathrooms or laundry rooms.

Since their operation requires minimum effort, vertical sliding windows are also a great choice in places where ventilation is required but the window itself is somewhat hard to reach. As vertical sliding windows don’t protrude beyond the frame, it’s extremely easy to add insect or security screens to them. Finally, vertical sliding windows are extremely easy to maintain. The sashes are usually easily removable, which allows you to effortlessly clean both sides of the glass inside your home. Milgard’s double-hung tilt windows feature sashes that tilt inward to enable easy cleaning of the exterior glass.

Aside from selecting the type, frame material, size and placement of your vertical sliding windows, you should always keep an eye on certain features to ensure your windows will serve you for decades to come. Consider the following factors:

♦  Operation

Vertical sliding windows contain two sashes in a single frame, one or both of which can slide up and down. Pay attention to how easy and smooth the operation is, as vertical sliding windows can often be placed in locations that are somewhat hard to reach. A good vertical sliding window is reliable, with sashes that don’t move unless you want them to.

♦  Security

Check the lock system if present. Depending on the size and placement of your vertical sliding windows, there’s usually nothing to be worried about when it comes to the safety of your home. However, since no two installations are the same, security should not be ignored. It’s important to note that Milgard’s products meet or exceed California’s forced entry codes.

♦  Ease of Maintenance

Windows with a wooden frame need to be painted or stained after a certain period. Exposure to moisture and varying temperatures can also warp the material. On the other hand, vinyl, fiberglass, and aluminum frames require little to no maintenance. Still, it’s important to choose the color of your windows carefully, as repainting these materials can be a bit harder than working with wood.

♦  Energy Efficiency

Make sure the windows you choose are well insulated and built with energy efficiency in mind. Going “green” is becoming more and more important, so most windows currently on the market include some energy-efficient options. Vertical sliding windows can provide better energy efficiency than some other types of windows as their construction is fairly simple so there aren’t many moving parts that stand in the way of a good seal. That means the heat transfer between the inside and the outside of your home is reduced to a minimum. Energy-efficient windows can be a great investment and even pay for themselves over time by reducing the cost of heating and cooling.

Frame materials

The frame material you pick for your windows plays an essential role in deciding which vertical sliding window is the ideal option for your San Diego home. Every frame material has its strengths and weaknesses that set it apart from the rest, so we’ll briefly cover the most important features of each.

Benefits of Vinyl Vertical Sliding Windows

♦ Affordable

♦ Energy efficient

♦ Weather resistant

Offering fantastic protection, vinyl is a great option for vertical sliding windows. Homeowners in Southern California choose vinyl window frames for their durability and stability. Vinyl is formed together with heat-welded joints, making the windows resistant to weather changes. These windows are also energy-efficient, meeting or exceeding ENERGY STAR® requirements. It’s also important to note that vinyl is relatively inexpensive and requires a minimal amount of maintenance. US Window & Door sells and installs vertical sliding windows from Milgard’s Tuscany, Trinsic, and Style Line Series. These windows are architecturally elegant and sound, with three internal and eleven external color options to choose from. If you’re looking for top-of-the-line vertical sliding windows in San Diego, Milgard’s vinyl windows sold and professionally installed by US Window & Door are the solution for you.

Benefits of Fiberglass Vertical Sliding Windows

♦ Incredibly durable

♦ Stunning design

Fiberglass window frames are a relatively new option when it comes to window frames. People usually go with fiberglass frames because of their endurance and longevity, knowing the windows are going to stand the test of time and be reliable for decades. US Window & Door also installs fiberglass vertical sliding windows from Milgard’s Ultra Series. Both lines of products offer various combinations of styles, colors, grids, and glass types to complement any San Diego home or office design. Each fiberglass vertical sliding window comes with SunCoat® Low-E insulated glass, which regulates the temperature inside your home while keeping out damaging sun rays. If you’re considering fiberglass sliding windows, Milgard’s Ultra Series provides unmatched durability and comfort.

Benefits of Aluminum Vertical Sliding Windows

♦ Great budget option

♦ High durability

♦ Ideal for large windows and doors

Aluminum frames provide a modern look while still complementing the home’s traditional architecture. It’s a solid material for its weight because the process in which the aluminum frames are extruded reinforces the metal. Aluminum is three times stronger than vinyl and more than forty times stronger than wood. US Window & Door proudly sells and installs high-quality vertical sliding windows from Milgard’s Aluminum Series. In addition to the standard model, Milgard offers thermally reinforced aluminum windows with increased energy efficiency. These windows include a thermal barrier between the exterior and interior glass panels which reduces the heat transfer to a minimum.
