Q: Are wood windows energy-efficient?

• <div><p>Wood windows fall in the middle of the <a href="https://www.angi.com/articles/window-material-types.htm">window frame materials</a> when it comes to energy efficiency. They&rsquo;re more insulating than aluminum and vinyl, but they aren&rsquo;t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer. </p></div>

Q: What is the difference between an awning window and a hopper window?

• <div><p>Awning windows are just like hopper windows except that they open the opposite way. Instead of opening inward, awning windows open outward with a hinge at the top. This creates a mini-awning within your window frame, which is where the name comes from. Hopper windows, on the other hand, open inward with a hinge at the bottom.</p></div>

Q: Is it expensive to add windows to a house?

• <div><p>Adding windows to a house is expensive. Budget roughly <b>$5,800 </b>to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed <b>$20,000</b>, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.</p></div>

Q: What energy efficiency benefits do modern windows offer?

• <div><p>Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.</p></div>

Q: Do egress windows open in or out?

• <div><p>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. </p></div>

"The windows were manufactured earlier than we expected and we were promptly contacted about installation. Although we were told the installation was scheduled for two days, the four man crew that arrived was able to finish in a single day! Each window was installed with the same consistency in quality and efficiency. Furthermore, the crew did an excellent job protecting our floors and furnishings in every room. When it comes to evaluating the installation crew, we couldn't be happier. Regarding price, we probably paid more than we should, but that's on us. We advise getting several other quotes first and then get Castle's quote. This will definitely help in your negotiating. The windows have definitely helped to eliminate draftiness in our home and helped to maintain a consistent temperature."
