Thermal King Patio door systems are designed for energy efficiency, security and ease of operation. Thermal King Patio doors have an exclusive Triple Glass Insulated EGIII KR Glass System.  It has multiple layers of Low-E glass with two insulated chambers filled with Krypton Gas.  Combined with our patented foam Super Spacer makes Thermal King’s Patio Doors 250% better and even 93 Percent more efficient than most other Patio doors in the Nation.

Easy to operate.  A tandem roller system spreads the door’s weight over two rollers at once, eliminating flat spots and making our patio doors super easy to slide no matter how many times they are opened and closed.  A heavy-duty fiberglass sill provides superior strength, resists frost and condensation and enables easier door operation.  A textured polyurethane surface provides anti-skid protection for sure footing every step of the way.  All Thermal King patio doors are backed with a lifetime transferable warranty.

Have Questions?

We are always available by phone or online to answer any questions you might have. 

Safe and Secure, our unique three-point locking system provides greater protection against forced entry.  The locking system engages at critical points along the jamb when the door is closed and pulls the panel up tight to the jamb for a feeling of complete security and peace of mind. Thermal King sliding patio doors are designed to provide a beautiful, seamless transition from your home to the outdoors.  They glide open smoothly – perfect for entertaining during the summer months – and close tight to protect your home from the elements throughout the year.  With a variety of panel configurations, size and style options, you can create a door that coordinates with the inside and outside of your home.
