"As the property manager of a large residential condo building, I had the pleasure of working with Clarus Windows for our full exterior and interior window cleaning. From start to finish, the experience was seamless. The crew was incredibly organized, professional, and pleasant to work with. Communication was top-notch, I especially appreciated the daily updates that kept our team and residents informed throughout the process. Aaron and the team at Clarus are an absolute delight to partner with, and I wouldn?t hesitate to work with them again. Highly recommend!"

"We chose Window Concepts because they brought product samples to our home to assist us in picking out a new entry door and sidelights. I wasn't pleased with the scheduling process for installation though. They called 45 minutes after our original installation appointment time and said they wouldn't be able to make it that day. I had to wait another week and though they were a few hours late, they did show up. Despite the wait the installers did a great job and we are happy with the finished product."

Windows FAQs, answered by experts

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

The rough opening refers to the framed space in the wall where the window will be placed. That means the full size of the space will be filled with both glass and frame once the new window is installed. For a standard window, a rough opening adds 1/2 inch to 3/4 inch to both the length and width.

The material around a window is simply called the window frame, but the individual pieces also have different names. The top portion of the frame is called the head, the side pieces are called jambs, and the bottom portion is called the sill. If you have multiple windows next to each other, you’ll also have a mullion, which is the frame piece that separates the individual windows. Windows stacked on top of each other are separated by a horizontal frame piece, which is called a transom.

The gas between window panes, typically argon or krypton, acts as a barrier to heat transfer. This means it helps keep your home warmer in the winter and cooler in the summer by preventing heat from passing through the glass. This gas layer also reduces condensation by stabilizing the temperature across the window and helps minimize noise. Essentially, it’s all about improving energy efficiency and comfort while lowering those utility bills.

Soundproof windows can be energy efficient, depending on the window type and manufacturer. Overall, triple-pane windows are more energy efficient than double-pane windows. However, according to the U.S. Department of Energy, a window’s energy-efficiency level is determined by multiple factors, including the frame material, if there’s any low-emissivity (low-E) glass, and the addition of spacers.
