Windows questions, answered by experts

Mulled windows are no less efficient than individual windows, provided the wall opening is the same size. Larger wall openings filled with glass will always reduce overall energy efficiency, as glass transmits heat more readily than a solid wall. If the windows that are mulled together have the same square footage as individual windows, you might actually see a small decrease in your electric bills, as mulled windows let in more natural light that can reduce interior lighting costs.

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Cons

Costly to install

It’s time to replace your windows if most or many are in poor shape. In that case, new fiberglass windows will increase the energy efficiency of your home and add to its overall visual appeal, inside and out. Replacing your windows also can allow you to find a style that better suits the character of your home.

Constant fixes can be expensive over time, and by replacing your windows, you can be at ease knowing you now have windows that function properly and make your home more energy-efficient.

Replacing basement windows can be worth the cost if replacement is necessary. If your windows are leaking and leading to water damage in your basement, it’s absolutely worth replacing them. Similarly, if your basement windows are no longer insulating your basement or pose a security risk, you need to replace them.

In some cases, you may be able to save money by repairing a window instead of replacing it. A contractor can help you decide the right course of action.

It’s easy to tell if you have low-E windows. Light a match or grab a pen light and hold it up to your windows. You should see multiple reflections in the window—four for double-pane windows. If one of the reflections is a slightly different color than the other three, you have low-E windows. If you don’t have low-E windows, all the reflections will be the same color.
