ENERGY STAR Vinyl Windows in Mequon

If you’re investing in replacement windows for your Mequon home, energy efficiency is one of the most important factors to consider. High energy efficiency will not only keep your home interior more comfortable, but it’ll also help your windows pay for themselves! After months and even years of reduced energy costs, your windows will show their true lifetime value.

All of Mad City’s windows are energy-efficient windows, earning ENERGY STAR’s “Most Efficient” rating. These windows are built with:

  • Sky Mirror Technology: This energy-efficient glass package includes multiple panes, low-e glazing, and gas-filled chambers. It improves heating and cooling efficiency while blocking 99.5% of harmful UV rays.
  • Four-Point Welding: Each corner of your window’s frame and sash will be machine-welded to create one continuous piece of vinyl—making it ultra-tough and durable.
  • Leak Stoppers: Spacers, weatherstripping, and thermal breaks are intelligently placed to prevent the seepage of air, water, and moisture.
