Q: How can you tell how old windows are?

• <div><p>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&rsquo;re unable to find either of these, then your window was manufactured locally (oftentimes called a &ldquo;shop window&rdquo;). </p><p>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&rsquo;t tell you when the window was installed on your home, but can get you close.</p></div>

Q: How often do I need to replace my windows?

• <div><p>Most properly installed and maintained <a href="https://www.angi.com/articles/how-long-windows-last.htm">windows last between 15 and 20 years</a>. Fiberglass windows last much longer than your average window. Since they don&rsquo;t warp from temperature changes, rust, or rot, you might be able to hold onto fiberglass windows for up to 40 years. On the other hand, poorly maintained wood windows may only last for a few years. </p></div>

Q: How does a bow window differ from a bay window?

• <div><p>The differences between a bay window versus a bow window involve the number of individual windows and the angle at which both windows extend from the home. A bow window has four to six individual windows that form a curve outside the exterior wall. A bay window usually has two small windows on the edges that angle outward from the exterior wall and a large window in the middle that&rsquo;s parallel to the home&rsquo;s exterior wall.</p></div>

Q: Do storm windows come with warranties?

• <div><p>Yes, most manufacturers offer warranties for materials and performance. Confirm terms before purchasing.</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>

Windows questions, answered by experts

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.

Most properly installed and maintained windows last between 15 and 20 years. Fiberglass windows last much longer than your average window. Since they don’t warp from temperature changes, rust, or rot, you might be able to hold onto fiberglass windows for up to 40 years. On the other hand, poorly maintained wood windows may only last for a few years.
