The Role of Window Spacers

The energy efficiency of replacement windows in Milwaukee is reliant on the parts that add to their insulating properties, such as spacers. They are metallic components that hold lites of glass apart at the right distance. Today, the use of metal spacers and sealants are considered the standard solution for insulating glass units. These spacers are typically made of aluminum and include a desiccant that can absorb residual moisture.

Window Spacers

Renewal by Andersen® of Milwaukee elaborates more on the role of window spacers.

Their Primary Function

Aside from keeping glass lites separated, window spacers accommodate stress caused by thermal expansion and pressure differences. They also serve as a moisture barrier to prevent water leakage and condensation. Lastly, they prevent the loss of special low-conductance gas.

Systems

There are two generic systems used in insulating glass units: a single-seal spacer and a double-seal system.

  • Single-Seal – An organic sealant, such as butyl, is applied behind the spacer and holds the unit together to prevent moisture intrusion. They are, however, not adequate to contain special low-conductance gases.
  • Double-Seal – A primary sealant seals the spacer to the glass to prevent gas loss and moisture, while a secondary sealant, usually in the form of silicone, provides structural strength. When stammered low-E coatings are used with double-seal systems, it becomes essential to remove the coating from the edge first for a better seal.

Our Replacement Windows

At Renewal by Andersen of Milwaukee, we offer replacement windows that feature warm edge spacers. For instance, our specialty windows in Milwaukee, WI, feature low-conductivity spacers made of stainless steel. It has a strong resistance against heat unlike other materials. This stabilizes the glass while providing insulation throughout the whole window.

Apart from this insulating component, our windows also come with High-Performance™ Low-E4® glass that can lessen heat that builds up in your home. They also feature our Fibrex® frame composite that offers superior insulation for a cozier home. Couple this with our airtight and seamless installation and you have the assurance of a highly energy-efficient window.

You can be sure that the components of every casement window in Milwaukee from Renewal by Andersen will lead to a livable home. Call us today at (877) 977-3639 to learn more about our windows.
