Energy-Efficient Design for Southern Climates

The South’s heat and humidity put extra strain on your windows—and your energy bill. Our energy-efficient replacement windows are dual pane, filled with insulating argon gas, and sealed to prevent air leaks. With ENERGY STAR® certified options, our windows help maintain comfortable temperatures inside while reducing the workload on your A/C. 

Built to Withstand Hurricanes and Humidity

Windows are one of your home’s most vulnerable points during a storm. LAS windows are engineered to meet the needs of Gulf Coast homes, with: 

  • Impact-rated glass options 
  • Reinforced vinyl frames that resist rot and corrosion 
  • Fusion-welded corners for superior water and air sealing 

We don’t use aluminum or fiberglass frames that can corrode or separate over time. Instead, we use vinyl windows with welded corners for long-lasting performance and superior protection.

Our window frames are made of high-quality vinyl that stands up the best in our hot and humid climate

We don’t use aluminum or wood frames because they simply don’t hold up in our climate. LAS replacement windows use fusion-welded vinyl frames that offer long-term performance, lower energy bills, and easy upkeep.
