Energy efficiency is first and foremost when choosing a replacement window. Thermal King Windows have an exclusive Triple Insulated EGIII KR IS 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 Windows 250% better and even 93 Percent more efficient than most other windows in the Nation!
Thermal King windows are built with maximum strength and security. Our frames and sashes are fusion-welded and guaranteed to never warp, sag, or bow. The fiberglass-reinforced sash rails also provide unsurpassed strength and durability. All windows over 26 inches have two flush-mounted sash cam locks for added safety. Our interior glazing bead deters glass removal from outside the home, which provides maximum security and a waterproof seal that protects the insulated glass. By adding ventilation limit locks, you have the peace of mind to know your windows are secure even when partially open.
