Windows questions, answered by experts

Bay windows are not easy to install because they are heavy and require specific tools and woodworking experience. You’ll also need to install a roof cab, flashing, and shingles. Ensuring the window is level and sealed can be tricky but it is important because it prevents air leakage and water from entering your home. Most often, an experienced window pro should install bay windows.

Yes, window manufacturers and installers can mull together three windows—or even more—for a more impressive appearance that lets maximum natural light into your home. However, you may have constraints regarding the total size of the wall opening. Your installer can help you determine what size wall opening is safe based on the structural load. In most cases, you can install additional supports to span the opening, like a steel I-beam, but this drastically increases the installation cost.

Depending on the window style and your home's layout, you can install replacement windows from either the inside or the outside. Many installations are done from the inside because it allows for better access and weather protection, but some exterior installs are easier for certain types of siding or trim. The key is choosing the approach that gives you the best access to the frame while keeping the existing structure intact.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.

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.
