Double Weatherstripping: Twin fin-seal weatherstripping provides a single fin seal on the sash sealing the exterior and a single fin seal in the frame sealing the interior.
Hardware: The 6000 operates on two sets of smooth rolling tandem nylon rollers. The sash pull rail is an integral part of the sash frame. The sash locks into an aluminum stiffened meeting rail.
Weep System: We utilize a staggered sill weep system with flush weep covers. This design provides excellent water drainage and air infiltration performance.
Frame: 2 1/2" frame depth and a slimline beveled frame design provide strength, beauty, and easy installation. Our frame and sash are fully fusion welded extruded UPVC.
Interlock: The 6000 has a full interlock with fin seal weatherstripping at the meeting rail providing a positive seal.
Aluminum Reinforced Sash: Gerkin reinforces the interlock rail of the sash and frame with extruded aluminum in order to reduce deflection and produce better overall window ratings.
Extruded Screen Frame: Gerkin offers more strength in its screen frame in order to give more reliability in screen durability. The screen is removable without removing the sash.
Outside Glazed Sash: The exterior glazing on the sash gives a smooth inside appearance. The fixed portion of the slider is interior glazed for easier glass replacement.
