What we do

Residential Replacement Window Experts.

Double Hung Windows

Double Hung Windows have two stacked, moveable sashes. This allows the window to move from top to bottom, or bottom to top, and provides a superior amount of airflow and easy cleaning and maintenance. 

  • Crafted with elegant detail
  • Built for strength and security
  • Engineered energy efficiency
  • Maintenance free design
  • Will never rot or warp
  • Performance guaranteed

Thermal King windows are built for strength, efficiency and durability, our windows are good for you, good for your home, and good for the environment.

Our patented windows not only save energy dollars, they save you time. Because the strong fiberglass reinforced frame is clad in durable vinyl, there is virtually no maintenance so you’ll never have to scrape and repaint your window frame ever again! And the convenient tilt-in feature on the double-hung model makes Thermal King windows easy to clean.

Sliding Windows

Sliding windows are great for rooms that have views that you don’t want obstructed. Sometimes referred to as “gliding windows” or “picture windows” these windows provide excellent airflow and easy operation. 

  • Designed for views
  • Built with ease of use
  • Light and energy friendly
  • Engineered for security
  • Narrow sight lines
  • Performance guaranteed

Built right for added strength. Thermal King windows are entirely fusion welded, an advanced manufacturing technique. Unlike windows that use staples, screws or caulk to hold the frame corners together, Thermal King fusion welds vinyl sections together to create a solid one-piece unit that won’t come loose or weaken over the years.

Casement Windows

Casement windows are attached to their frame by one or more hinges at the side. Unlike hung or sliding windows, casement windows typically operate outward with a mechanical crank and can be great for controlling air flow. 

  • Color match for beauty
  • Hinges provide security
  • Full opening for cleaning
  • Great for kitchens
  • High energy efficiency
  • Performance guaranteed
