"Install crew was perfect. No dust, no mess. Complete cleanup, and a perfect airtight install. For years we have had winter management strategies. Closing off room on the north side... and running space heater in those rooms during use. After installation of the ProEdge windows these rooms are as warm as the rest of the house. AMAZING! Recent warm days prove the advantage of triple glazed low-E windows, too. Nice and cool inside. I searched for years for new windows that met MY specifications . As a career engineer I am happy to recommend ProEdge to anyone. Their attention to detail is superb."

Windows questions, answered by experts

There are many standard window sizes. The most common windows, single or double-hung models, typically range from 2-feet by 3-feet up to 4-feet by 6-feet. Of course, sliding windows will be wider than they are tall, though the standard sizing follows the same measurements.

No, windows cannot be made 100% soundproof. Even the most advanced setups still allow some sound to pass through because windows are designed to let in light and are not completely sealed from the outside. While you cannot achieve complete silence, significant noise reduction is possible, with some noise-reduction windows blocking up to 95% of outside noise.

The goal is to minimize air gaps, add mass, and reduce vibration. To block out as much noise as possible, consider hiring a professional to install new double-pane, triple-pane, or laminated windows. You can further enhance soundproofing with airtight seals, glass inserts, shutters, or sound-dampening curtains. With the right upgrades, you can block out traffic, neighbors, and other city noise to a much quieter level.

Most modern egress windows installed in basements open outward into a window well, although some older homes have in-swing windows. Egress windows, like casement windows used in other parts of the home, such as bedrooms and bathrooms, may open inward, and these windows are often larger than outward-opening windows.

A double-hung window features two operable sashes, meaning it has an upper window part and a lower part that can both open to let in fresh air. A picture window has one fixed glass panel that doesn’t open. Double-hung windows cost about $200 to $2,500, while picture windows cost about $200 to $1,900.

Yes. Thermal pane windows can be customized to fit a variety of different window sizes and dimensions. A contractor or manufacturer can usually offer custom sizing options based on your specific window requirements. You should consult with professionals who can assess your needs and provide the appropriate custom window solutions for your home.
