Extruded anodized aluminum sill is corrosion resistant ;

Integrated rolling rail, ready for screen installation ;

Double drainage system (internal and external). Maximizes water evacuation ;

Two valves (internal and external) create an air pocket, reducing the pressure between inside and outside. Optimizes air and water tightness ;

Step-shaped sill profile. Prevents water infiltration ;

The hybrid frame is mechanically assembled from aluminum and PVC merged by a rolling process. Depth: 6 1/4 in. (159 mm) ;

Double weatherstripping on the frame and triple on the sill. Superior performance with extreme resistance to wear and tear ;

Mechanically assembled hybrid sashes made from aluminum and PVC merged by a rolling process ;

Integrated invisible seal along circumference of the sashes. Eliminates air and water infiltration. (Not shown) ;

Corner assembled by crimping process (aluminum) and screwing (PVC) at a 45 degrees angle ;

Invisible galvanized steel reinforced meeting stiles for maximum rigidity. (Not shown.) ;

7/8 in. clear insulated tempered glass with "thermal edge" energy-saving spacer. Excellent energy efficiency and soundproofing ;

Glazing bead system for glass retention. Facilitate replacing glass if necessary ;

Tandem ball bearing rollers. Smooth and silent operation ;
