Replacement Aluminum Windows

For a modern homeowner, aluminum window replacements are a great option. They’re durable, long-lasting, easy to maintain, and they have a slim profile. Thermal breaks are strategically put into different sections of the frame for a higher level of insulation, since aluminum is an effective heat conductor. These molded sections are usually screwed or welded together. You will usually spend more on aluminum windows in comparison to vinyl replacement windows and fiberglass windows. However, they are sometimes still cheaper than the architecturally appealing wooden window styles.

  • Due to aluminum frame windows’ slim design, aluminum windows are a sleek, attractive option for homeowners seeking a modern look. Although it requires more maintenance later on, aluminum frames can also be painted if you ever wanted to spruce them up in the future.

Thing to Consider Before Replacing

  • One thing to consider when replacing home windows with aluminum frame windows is that you are going to take a hit in terms of energy efficiency even with their thermal breaks. Aluminum frames conduct heat much faster than other options and therefore heat is let into your home at a much faster rate causing your home central air conditioning system to work even harder.
  • Aluminum frames are the second most expensive window frame type behind wooden frame replacement windows. While aluminum is very durable and holds up to weathering better than most other frame types, it can dent easily if mishandled. Dented aluminum windows are difficult to repair and often have to be replaced completely or filled and painted to mask the dent which in turn costs more for maintenance.

Aluminum Window Repair vs Replacement

If your home’s aluminum windows are already double paned, you might consider repairing them versus replacing them depending on the extent of the damage you can see. If the window is intact for the most part, you will want to assess the current condition of your aluminum window’s frame, glass, and other parts of your window as a whole before deciding on repair or replacement. This is where a reliable contractor will often come in handy to help you make the decision as to what’s the best option.

As a general rule of thumb, if your aluminum window repair is for a single pane window then it’s often best to simply replace the entire window with a higher quality energy-efficient double pane replacement window. In fact, when replacing windows in states like Texas, manufacturers will only install more energy efficient aluminum windows due to the fact that they transfer heat so easily making it hard to control your home’s temperature in very hot climates. Many homeowners will opt to upgrade to a higher quality window frame material such as vinyl or choose a fiberglass window replacement in order to keep their home cooler and to avoid having windows that allow for air leakage overtime.

Are aluminum windows better than other windows?

While aluminum windows are more expensive than vinyl or fiberglass replacement windows, they hold up to weathering more effectively and are aesthetically pleasing in modern homes. They’re also less expensive and more durable than replacement wooden windows — and with the addition of thermal breaks, they’re much more energy efficient than the aluminum frames on the market 20 years ago. However, their energy efficiency issues (they allow heat in very easily) are the main reason homeowners will opt to replace their windows with a different frame material. All other window frame type offer more energy efficiency to help save on long-term heating and cooling bills.

Thermal Breaks in Aluminum Windows

When shopping for aluminum windows, it’s important to ask about the frame’s thermal breaks and to look at a cross section of the frame to compare the number of breaks between frames. A frame with more breaks will generally be more efficient overall.

Thermal breaks are spaces between sections of an aluminum window frame. Aluminum frames are mostly hollow on the inside, and the chambers that make up the frame are disconnected from one another. Each open section where the two sides don’t connect is a thermal break, and within these breaks, insulators and resins are inserted. This makes the frame more durable and cuts down on the pathways for heat to travel through the aluminum.
