When buying replacement windows in Philadelphia PA or the surrounding areas, it helps to understand the importance and function of each part of the window. You won’t have a difficult time finding the right product when you know how each part affects the overall performance of the window. One of the things you need to know about is the spacer.
What’s a window spacer? Read on to learn how window spacers keep the glass stable and how they make your windows more energy-efficient.
What’s a Spacer and What Does It Do?
The spacer is the piece that separates the glass panes of a dual-pane window. It supports windows from the stress caused by pressure differences inside and outside and thermal expansion. Furthermore, it acts as a moisture barrier that blocks water and vapor from getting through the glass and into your home. It also helps prevent condensation from forming on your window’s edge by creating an insulating barrier.
Window spacers do more than just keep the glass apart, though. They also accommodate stress included by thermal expansion and pressure differences, which is common in areas that experience four distinct seasons. The spacer also doubles as a moisture barrier that prevents the passage of water or water vapor that would otherwise fog up the unit. Additionally, it provides a gas-tight seal that prevents the loss of any special low-conductance gas in the air space.
Finally, window spacers are also responsible for creating an insulating barrier that reduces the formation of interior condensation. This is one of the more important roles of the spacer, as it prevents one of the most common problems in both old and new windows. By doing so, the spacer helps extend the service life of the window.
When it comes to window replacement in Philadelphia, you have to make sure that the spacer is made from high-quality, durable material. If not, it may move and break the seals, which can lead to many problems including premature window failure.
Standard Insulating Glass Units
The standard for insulating glass units (IGUs) is to use metal spacers – like aluminum – and sealants. Manufacturers can choose between two systems for their windows. In the double-seal system, the primary sealant secures the spacer to the glass to avoid transfer of moisture and loss of gas. The secondary sealant adds structural strength to the windows. In a single-seal system, the sealant is applied behind the spacer to block moisture from getting through and secure the unit.
Some manufacturers use plastic for spacers. The problem with plastic is that it has the tendency to emit gas when exposed to the sun’s heat. This can result in a chemical fog in the space between the panes that can compromise visibility.
Renewal by Andersen® replacement windows do not use aluminum spacers, as aluminum lets heat escape during the winter and allows it to enter your home during the summer. For optimal energy efficiency, Renewal by Andersen windows come with low-conductivity spacers made of stainless steel. Our stainless-steel spacers are stronger than aluminum spacers and resist heat far more effectively.
