"John replaced the glass sash on my Anderson casement windows. He did the complete job in one day, at a cost of 15% of the Anderson replacement window quote. I highly recommend Window MD.. They were perfect!"

"I used Star Windows and Doors LLC to replace the windows in our home. It was a pleasure to work with them - they were very responsive, and from start to finish the entire process smooth. The windows themselves look beautiful, and the installers did a great job with all the little details! I would recommend Star Windows and Doors LLC."

Windows questions, answered by experts

When it comes to your pocket, opting for energy-efficient windows can lead to an average of 12% in energy bill savings. That totals to yearly energy savings between $100 and $600. However, the exact amount you’ll save hinges on factors like your local climate and the number of windows in your home.

If your double-glazed windows are letting in a lot of noise, it might be because of improper installation. You may need to apply an acoustic caulk around the window to close any gaps or hire a window installation expert to fix the windows. Double-glazed windows are typically more effective at reducing noise when they have thicker glass panels or have a gas filling, like argon or krypton, between the two glass panels.

Glass block windows offer several unique benefits over traditional windows, and they create a much more unique look. These specialty windows offer added privacy while allowing natural light into the space, which is why they’re a popular choice for bathroom features. They also provide increased security as glass blocks do not open unlike traditional windows. Plus, they provide increased energy efficiency, lowering energy costs and preventing drafts.

Soundproof windows can’t completely block all noises, but they will significantly reduce sound from the road, sky, or your neighborhood’s weekend activities. Choose a soundproof window with an STC rating of at least 45 to block bass tones or loud conversations. Laminated glass windows can reduce noise by 75%. You can also add noise-reducing curtains to further muffle loud noises.

Most manufacturers have their name imprinted somewhere on the window, such as the spacer bar, hardware, or frame. Other manufacturers will include an identification number printed on the glass itself. If you’re unable to find either of these, then your window was manufactured locally (oftentimes called a “shop window”). 

With a manufacturer name (or even better, the identification number) you can attempt to research the information to find out when the product was made. Keep in mind this won’t tell you when the window was installed on your home, but can get you close.
