Insuliner Primary Thermal Barrier Window

The Insuliner window is actually two windows, one serving as the primary window and one serving as the storm window, both mounted in a common wood frame. The windows are separated by over an inch of wood, one of natures best insulators, to guard against the conductivity of cold air from the outside through the metal frames to the inside. It virtually eliminates frosting, condensation, and heat loss in the winter, and improves air conditioning in the summer!

Features & Benefits

• Nailing Fin
  Heavy duty extruded aluminum nailing fin is part of the window. Helps ensure square installation and adds strength to the frame.
• Screen Frame
  Are made of heavy rolled form extrusions for added rigidity.
• Automatic Locking Sash
  When closed - all sashes are automatically locked to frame and interlocked at center mullion ensuring a positive weather tight seal.
• Metal Rollers in Nylon Housing
  Aluminum rollers are placed into nylon housings and inserted into window glass frames. There's no grating, grinding, or sticking. The INSULINER is a true rolling window.
• Two Piece Sill and Center Mullion
  Sloped two piece sill adds strength and provides for superior water drainage. Two piece center mullion reduces bowing and adds vertical support between head and sill.
• Thermal Break
  Ture wood separation provides one of natures best thermal breaks between exterior and interior window. Heavy wool pile weather stripping around perimeter of windows and at interlock prevent both air leakage and infiltration.
