Frequently Asked Questions

Frequently Asked Questions About Slider Windows

What are slider windows called?

Slider windows are also known as sliding or gliding windows. They are a modern window style that opens horizontally to provide wide views, lots of natural light, and plenty of fresh air.

How do slider windows operate?

These windows operate on a track with tandem brass rollers, allowing the sash to glide smoothly for easy opening and closing. The effortless sliding action makes them suitable for spaces where reaching might be difficult.

What are the disadvantages of a sliding window?

Older models sometimes had issues with sticking tracks or faulty hardware. However, today’s high-quality vinyl sliders are engineered for an effortless glide and require very little effort in maintaining them.

Are slider windows a good choice for my home?

Yes, they are a fantastic choice. Their space-saving design provides easy access to the outdoors and their clean lines fit almost any home style.

What is the average cost of a slider window?

The cost varies based on size, the chosen frame material, and the glass package. Upgrading to energy-efficient glass is a great investment as it reduces heat transfer and lowers your energy bills.

Can I customize slider windows for my home?

Absolutely. You can create a unique look that matches your home’s style. We offer options for decorative grids, different colors, and various hardware finishes.

Do sliding windows work well near patios or exterior walkways?

They are perfect for those spots. Unlike an awning window that swings out, a slider won’t block a walkway. They are also great for a covered patio or a sunroom, and each window includes a screen to let air in while keeping bugs out. They look great in a home gallery, too.
