Alexandria Windows with Warm Edge Spacer Technology 

You might have the most efficient heating and cooling system on the market, but those energy savings could be going out window, literally. Windows are responsible for up to 30 percent of heat gain and loss. That means old, inefficient windows are compromising your comfort and your wallet. 

Windows with warm edge spacer technology solve that problem. Here’s how: 

Understanding Warm Edge Spacer Technology 

Windows are supposed to keep the weather outside where it belongs, but many are made with aluminum and metal frames. That’s a problem because aluminum offers very little thermal resistance, allowing cold or hot air to seep in and out. This is particularly a problem along the edges of the frame were spacers are placed between panes of glass. Spacers made of aluminum allow the heat your furnace worked hard to make to slip out the window.  

Warm edge spacers are an effective alternative to aluminum, minimizing energy losses. 

In addition to saving energy, warm edge spacers have the following benefits: 

  • Prevent cracks: Windows expand and contract with temperature changes. Because metal spacers are inflexible, windows can develop cracks. Warm edge spacers are made of softer material, helping absorb stress, preserving glass integrity.
  • Block water vapor: Warm edge spacers seal against condensation, reducing moisture damage and mold growth along the window’s edge.
  • Stop gas leakage: Manufacturers fill the space between glass panes with argon gas to improve efficiency. However, the gas can leak through aluminum spacers as the glass expands and contracts. Warm edge spacers are a more effective seal.
