Casement window opens to the outdoors

Casement System 1400 is appropriate for any building application—residential, commercial or institutional.

  • The window swings outward to 90 degrees with very little effort
  • Exterior glass can be easily reached for cleaning
  • The sash features a contoured shape that makes for elegant narrow sight lines

Engineered to be Energy Efficient

The sash is designed to seal against the frame with three continuous seals to keep out wind and weather.  And double-wall construction increases strength, permits thorough water drainage and decreases heat loss through the sash.


Multiple locking points around the sash make the window secure for tamper resistance and withstanding strong wind pressures.

Triple weather seals guard against air and water infiltration.
  • Ease of operation: a single handle unlocks the multiple locking points.  The strong Maxim-Series operator allows the window to open 90° effortlessly. The hinge design allows you to conveniently reach the exterior of the glass for washing when the window is open.
  • Screw bosses securely hold fasteners in place, so that operators and other hardware can't work themselves loose over time.
  • Security: multiple locking points surrounding the sash mean that the window is secure for tamper resistance and withstanding strong wind pressures.
  • Fusion welded for strength: sash and frame corners are miter-cut and welded, eliminating caulking and joints that may loosen and leak.
  • Triple seal design: the sash is designed to seal against the frame with three continuous seals and a dual cavity, pressure-equalized configuration.
  • Multi chambered walls: double-wall construction increases strength, permits thorough water drainage and increases energy efficiency.
  • Architectural rating: able to withstand heavy use, this window achieves a grade 70 rating (a rating often associated with resisting winds in excess of 130 mph) even when made in the large 3' x 5' "architectural" size. The rating signifies that the windows passed a battery of 2,500 cycles of opening, closing and locking, "misuse" torsion and loading, and subsequent retesting to prove continued air and water infiltration resistance.
  • Interior glazing: this glazing style presents a seamless sash to the outside elements and the effects of potential tampering.
  • Well-proportioned sight lines:
  • Glass options: among the options are high-performance and decorative glass.
  • Longevity of vinyl: literally carefree, our windows resist corrosion from pollutants, never need painting and can be cleaned with soap and water.
